Abstract
The assessment of the comparative effect of biosal (phytopesticide), deltamethrin, and lambda-cyhalothrin (pyrethroids) were made against two fodder pests, Hermolaus modestus and Hermolaus ocimumi by filter paper impregnation method. The activity of total protein contents, GPT (glutamic-pyruvic transaminase) and GOT (glutamic oxaloacetate transaminase) were affected in Hermolaus modestus and Hermolaus ocimumi against biosal, deltamethrin, and lambda cyhalothrin. The activity of total protein contents in H. modestus was 31.053%, 4.607%, and 24.575%, against biosal, deltamethrin, and lambda-cyhalothrin, respectively. The activity of total protein contents was observed as 24.202%, 15.25%, and 56.036% against deltamethrin, lambda-cyhalothrin, and biosal, respectively in H. ocimumi. The activity of GOT was observed as 98.675% for biosal 33.95% for deltamethrin and 83.619% for lambda-cyhalothrin in H. modestus. The GOT activity was estimated in H. ocimumi as 78.831%, 47.645%, and 71.287% against biosal, deltamethrin, and lambda-cyhalothrin, respectively. The efficacy of GPT enzyme against biosal, deltamethrin, and lambda-cyhalothrin was calculated as 89.26%, 73.07%, and 47.58%, respectively in H. modestus. The H. ocimumi showed GPT activity as 77.58% for biosal, 68.84% for deltamethrin, and 52.67% for lambda-cyhalothrin, respectively.

1. Introduction
Livestock animals are normally fed on green food, hay, and fodder crops. In Pakistan, two types of fodder crops named temporary and permanent crops are being used. The continuous use of land for the cultivation of fodder crops or appetizing forage crops is stated as a permanent type. Temporary fodder crops are grown and harvested like any other major crop. For enormous cultivation, it was necessary to protect our main and fodder crops from their pests. The materials or chemicals belong to pesticides were selected and applied for the huge quantity and good quality of crops. The traditional insecticides may interrupt our environment and health. It is required to use alternate suitable strategies for pest control. Different plant extractions have been isolated from different herbal medicinal products including flavonoids, phenols, alkaloids, and terpenoids. These remedial products play a vital role to prevent vulnerable organisms (Adjaye-Gbewonyo et al., 2010ADJAYE-GBEWONYO, D., QUAYE, E.C. and WUBAH, D.A., 2010.

) Biosal is one of the most famous commercial products, extracted from neem plant and its member of the family Meliaceae. The neem (Azadirachta indica) is an indigenous plant in India (Hashmat et al., 2012HASHMAT, I., AZAD, H. and AHMED, A., 2012. Neem (Azadirachta indica A. Juss): a nature’s drugstore: an overview. International Research Journal of Biological Sciences, vol. 1, no. 6, pp. 76-79.). Biosal is an effective phyto-pesticide and used to control the different agricultural pests (Maithani et al., 2011MAITHANI, A., PARCHA, V., PANT, G., DHULIA, I. and KUMAR, D., 2011. Azadirachta indica (neem) leaf: a review. Journal of Pharmacy Research, vol. 4, pp. 1824-1827.). The previous study shows the residual and natural impact of neem oil against cotton mealybug (Phenacoccus solenopsis) by utilizing leaf and surface treatment method. The various concentrations of neem oil affected the fertility, mortality, and life span of cotton mealybug (Mamoon-ur-Rashid et al., 2012MAMOON-UR-RASHID, M., KHATTAK, M.K. and ABDULLAH, K., 2012. Residual toxicity and biological effects of neem (Azadirachta indica) oil against cotton mealybug, Phenacoccus solenopsis Tinsley (Sternorrhyncha: pseudococcidae). Pakistan Journal of Zoology, vol. 44, no. 3, pp. 837-843.). The cowpea seeds extract, protected flower, and B125 has been applied against Callosobruchus maculatus. The high mortality rate of Callosobruchus maculatus showed with V. rosea and the low mortality rate was found with C. papaya (Louise et. al., 2018LOUISE, K.M., HABIBA, K., SIDONIE, F.T. and TCHUENGUEM FOHOUO, F.N., 2018. Management of Callosobruchus maculatus F.

Journal of Entomology and Zoology Studies, vol. 6, no. 2, pp. 1017-1027.). Researchers worked on cowpea pest Callosobruchus maculatus (F.) and found the mortality rate after 24, 48, and 72 h of Castor and Hazelnut oil exposure (Haghtalab et. al., 2009HAGHTALAB, N., SHAYESTEH, N. and ARAMIDEH, S., 2009. Insecticidal efficacy of castor and hazelnut oils in stored cowpea against Callosobruchus maculatus (F.) (Coleoptera: bruchidae).

).
Pyrethroids are synthetic pesticides and may cause hazards to agricultural plants. Different pyrethroid groups play an important role in pest management. Deltamethrin is a non-cumulative synthetic pesticide and acts as a fast-neurotoxic agent and easily available in Pakistan (Arif et al., 2012ARIF, S., NAQVI, S.N.H., RAJPUT, T., YOUNUS, M.F. and ARIF, I., 2012. Effect of acorus calamus, biosal® and deltamethrin on fecundity of Callosobruchus analis. FUUAST Journal of Biology, vol. 2, no. 1, pp. 131-133.). Lambda-cyhalothrin is the synthetic pyrethroid, insect inhibitor and having insecticidal active ingredient, investigated the inhibition effect of biosal, deltamethrin, and lambda-cyhalothrin in Hermolaus modestus (Hussain and Zahid, 2016HUSSAIN, S.I. and ZAHID, M., 2016. Comparative effect of Biosal® and pyrethroids (deltamethrin and lambda cyhalothrin) on enzymatic activity and total protein contents in Hermolaus modestus. FUUAST Journal of Biology, vol. 6, no. 2, pp. 241-246.). The leaf plunge bioassay method reported in detail describes that pyrethroid (cypermethrin) was harmful to the environment and may cause problems (Foster et al., 2002FOSTER, S.P., DENHOLM, I. and THOMPSON, R., 2002.

were found high susceptibility of soybean aphid against chlorpyrifos, lambda-cyhalothrin, esfenvalerate, and dimethoate but aphids showed less vulnerability after 48 h to neonicotinoid imidacloprid. The level of human enzymes GPT, GOT and ALP was increased when exposed to deltamethrin, cypermethrin, polytrin-C, diazinon, monocrotophos, DDT, and DDE pesticides (Azmi et al., 2006AZMI, M.A., NAQVI, S.N.H., AZMI, M.A. and ASLAM, M., 2006.

). Ambreen and Javed (2015)AMBREEN, F. and JAVED, M., 2015. Assessment of acute toxicity of pesticides mixtures for Cyprinus carpio and Ctenopharyngodon idella. Pakistan Journal of Zoology, vol. 47, no. 1, pp. 133-139. used a mixture of pesticides including chlorpyrifos, endosulfan, and bifenthrin against Cyprinus carpio and Ctenopharyngodon idella. This mixture was found very dangerous to fishes and habitats.
This work aims to compare the effect of natural and synthetic pesticides on the two different fodder pests, which may be harmful to main crops. Fodder crops are important for livestock animals, moreover, recent increases in industrialization and urbanization create stress on agriculture and the environment, so there is a need to prevent the unnecessary loss and degradation of crops and the environment by the proper use of suitable pesticide. Therefore, this effort will provide an approach to understand the phyto and synthetic pesticides to control fodder and main crop pests.
2. Materials and Methods
2.1. Collection and rearing of pests
Both species Hermolaus modestus and Hermolaus ocimumi were collected on Ocimum basilicum L and Medicago sativa (L) from the different areas of Karachi, Pakistan. The adults of both collected pests were kept separately in 9cm washed Petri dishes in the laboratory for experiment.
2.2. Preparation of pesticides concentration
Five different concentrations of three pesticides were prepared for the treatment of adult Hermolaus modestus and Hermolaus ocimumi. Charles’s formula was used for the preparation of different concentrations (Equation 1).
The different concentrations of biosal, deltamethrin, and lambda-cyhalothrin were prepared separately in distilled water after some preliminary experiments, the already prepared concentrations of biosal 4, 5, 6, 7, and 8 percent used for the treatment of Hermolaus modestus and 3.5%, 4.0%, 4.5%, 5.0%, 5.5%, and 6.0% applied on the Hermolaus ocimumi One percent stock solution of deltamethrin were used to prepare for various concentrations of deltamethrin. After a few trial tests chosen doses of deltamethrin as 0.0002%, 0.0004%, 0.0009%, 0.0018%, and 0.0037% for the treatment of H. modestus and 0.015625%, 0.03125%, 0.0625%, 0.125%, 0.25% and 0.5% concentrations of deltamethrin were prepared for the treatment of H. ocimumi. Five different concentrations of lambda cyhalothrin were prepared from 1% stock solution for the treatment of both species. The prepared concentrations of lambda-cyhalothrin were 0.125%, 0.25%, 0.375%, 0.5% and 0.625% for the treatment of H. modestus and prepared concentrations were 0.1625%, 0.175%, 0.1875%, 0.2%, 0.2125% and 0.225% for the treatment of H. ocimumi.
2.3. Process of treatment
The experiment was conducted in eighteen sets of 9 cm washed Petri dishes by filter paper impregnation method for the treatment of Hermolaus modestus and Hermolaus ocimumi. One set of three Petri dishes were marked as untreated (controlled) and five sets for each pesticide's concentration were labeled as dilutions. Each set of Petri dishes were lined with the same size filter paper and prepared concentrations of biosal, deltamethrin, and lambda-cyhalothrin were pipetted out in Petri dishes separately. The same-sized of twenty adults of H. modestus and H. ocimumi were transferred in each petri dish separately for the experiment. The mortalities were observed in treated and untreated Petri dishes after twenty-four hours of tested compounds, biosal, deltamethrin, and lambda-cyhalothrin.
2.4. Preparation of homogenous compound by dry weight extraction method
Homogenous was prepared by the dry weight extraction method. In this method untreated (control) and pesticides treated insects of both species were dried up in a desiccator until the weight was constant. Sartorius model CP 224S was used to measure the weight (0.5 gm.) of both species. The desiccated and measured specimens of both species were crushed in 4 ml distilled cooled water separately and then homogenized in ULTRA – TURRAX – T25 (JANKE $ KUNKEL- Homogenizer). Heraeus model (Multifuge- 3 S-R) used for centrifugation at 3000 rpm for 25 minutes at a temperature of 4 °C. This supernatant was kept in different test tubes and labeled with pesticides and species names.
2.5. Estimation of total protein contents
The total protein contents were estimated by Modular P analyzer: ACN, 402 (Roche/Hitachi Cobas® analyzer). The Roche Diagnostic protein assay is based on the method described by Iwata and Nishikaze (1979)IWATA, J. and NISHIKAZE, O., 1979. New micro-turbidimetric method for determination of protein in cerebrospinal fluid and urine. Clinical Chemistry, vol. 25, no. 7, pp. 1317-1319. http://dx.doi.org/10.1093/clinchem/25.7.1317.

.
In this method, protein reacts with benzethonium chloride. This action carries out in the basic medium for producing the turbidity that is more stable and uniformly dispersed than that observed with the sulfosalicylic acid (SSA) or trichloroacetic acid (TCA) techniques. This assessment shows an under-recovery of Y-globulin compared to albumin of about 30%, and without the involvement of magnesium ions (Mg2+) due to the addition of ethylene diamine tetra acetic acid (EDTA).
2.5.1. Test principle
The alkaline solution was used for pre-incubation of sample and EDTA (Ethylene diamine tetra acetic acid) compound which reconstructed the protein and then removes interference from (Mg2+) magnesium ions. After the addition of benzethonium chloride, turbidity is produced and then read at 505 nm. Reagent (R1) used as Sodium hydroxide: (530 mmol L-1); EDTA – Na: (74 mmol. L-1) and reagent (R2) Benzethonium chloride: (32 mmol L-1). The analyzed concentration of each sample is automatically calculated by the analyzer.
2.6. Estimation of glutamate oxaloacetate transaminase (GOT)
Roche/Hitachi 912 analyzer: ACN 143 was used for GOT estimation. The chemical reagents were used, R1: TRIS buffer: (100 mmol. L-1), PH 7.8; L-aspartate: (300 mmol. L-1); NADH (yeast): (0.23 mmol. L-1); MDH ≥ 0.53 U mL-1 8.83 µKat /L; LDH ≥ 0.75 U. mL-1 (12.5 µKat/L); preservative. R2: α – Ketoglutarate: (75 mmol. L-1); preservative.
2.6.1. Test principle
This experiment was performed in a specified standardized method. Reagents R1 and R2 were added to the sample then chemical reactions started. Glutamate oxaloacetate transaminase (GOT) catalyzed the interconversion of α – Keto acid and amino acid by transfer of amino groups.
This equilibrium reaction catalyzed by AST
NADH oxidized to NAD+.
2.7. Estimation of glutamate pyruvate transaminase (GPT)
The evaluation of Glutamate pyruvate transaminase (GPT) was accomplished by CAN – 098: 912 analyzers (Roche/Hitachi). The standardization method for GPT determination is proposed by the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) (Schumann et al., 2002SCHUMANN, G., BONORA, R., CERIOTTI, F., FÉRARD, G., FERRERO, C.A., FRANCK, P.F., GELLA, F.J., HOELZEL, W., JØRGENSEN, P.J., KANNO, T., KESSNER, A., KLAUKE, R., KRISTIANSEN, N., LESSINGER, J.M., LINSINGER, T.P., MISAKI, H., PANTEGHINI, M., PAUWELS, J., SCHIELE, F., SCHIMMEL, H.G., WEIDEMANN, G. and SIEKMANN, L.., 2002.

4. Discussion
In the current study comparative effect of biosal, deltamethrin and lambda-cyhalothrin were tested against two fodder pests, Hermolaus modestus and Hermolaus ocimumi. Filter paper impregnation method was chosen for the determination of the activity of total protein contents, GOT, and GPT enzymes in both fodder pests in laboratory conditions. The filter paper impregnation method was also used by Zafar et al. (2010)ZAFAR, S.M.N., TARIQ, R.M., ASLAM, M., BREUER, M., NAQVI, S.N.H. and PERVEEN, R., 2010. Study of resistance in Sitophilus oryzae against biosal, cypermethrin and phosphine on the basis of toxicity values. Pakistan Journal of Entomology, vol. 23, no. 1-2, pp. 19-26. for evaluation of resistance in Sitophilus oryzae (Rice weevil) in susceptible strain, Karachi strain, and Lahore stains against biosal, cypermethrin, and phosphine. They found KS and LS were more resistant to Cypermethrin and Phosphine. In this work, the total protein contents were found in declined in adults of H. modestus as 31.053%, 4.607%, and 24.575% against biosal, deltamethrin, and lambda-cyhalothrin respectively. The maximum effect on the activity of total protein contents in H. modestus was reported by Deltamethrin as 4.607% and the minimum effect on the activity of total protein contents was determined as 31.053% by biosal. The decreased value of total protein contents was observed as 56.036%, 24.202%, and 15.25% against biosal, deltamethrin, and lambda-cyhalothrin respectively in H. ocimumi. Lambda cyhalothrin has a maximum effect of 15.25% on the activity of total protein contents and biosal showed a minimum effect of 56.036% on the activity of total protein contents. In both species, synthetic pesticides were found more toxic than biosal. This study showed a decrease value of protein contents due to degradation in metabolic activities of insects. Nikhat et al.

Trakia Journal of Sciences, vol. 9, no. 1, pp. 28-36. assessed the bio-activity of edible essential oil extract against Tribolium castaneum (Herbest).
In the current investigation, the activity of GOT (glutamic oxaloacetate transaminase) was observed in H. modestus as 98.67%, 33.95%, and 83.61% against of biosal, deltamethrin, and ƛ-cyhalothrin respectively. The GOT value was observed in H. ocimumi as 78.831%, 47.645%, and 71.287% when treated with biosal, deltamethrin, and lambda-cyhalothrin respectively. The maximum GOT activity was noted as 98.67% in H. modestus and 78.831% in H. ocimumi for biosal. The minimum value of GOT was recorded as 33.95% in H. modestus and 47.645% in H. ocimumi for deltamethrin.
The activity of GPT (glutamic-pyruvic transaminase) was determined as 89.26% for biosal, 73.07% for deltamethrin, and 47.58% for lambda-cyhalothrin in H. modestus, and GPT activity was observed as 77.58%, 68.84%, and 52.67% in H. ocimumi after the treatment of biosal, deltamethrin and ƛ-cyhalothrin respectively. The high value of GPT activity was observed as 89.26% against biosal and low as 47.58% against lambda-cyhalothrin in H. modestus. Maximum and minimum GPT activities were observed in H. ocimumi as 77.58% for biosal and 52.67% for lambda-cyhalothrin. This result is near to other research work. Tabassum et al.

5. Conclusion
This effort shows that both fodder pests are very vulnerable and can damage crops and animal food. The application of biosal, deltamethrin, and lambda-cyhalothrin against Hermolaus modestus and Hermolaus ocimumi on the activity of total protein contents, GOT and GPT was demonstrated that synthetic pesticides are more acutely toxic to fodder pests than phytopesticide. Although synthetic pesticides are constructed to destroy undesirable living organisms, but continuous use of synthetic pesticides is fabricating enormous unwanted impact on our ecosystem. The above-mentioned results show that lambda-cyhalothrin and deltamethrin (synthetic pesticides) are highly toxic and venomous than biosal (phytopesticide). The impact of pesticide toxicity can be shown as (Deltamethrin> Lambda cyhalothrin> Biosal). So, biosal was recognized as a friendly environment phytopesticide and also very effective to control the vulnerable species. The overall conclusion was suggested that phytopesticides are very effective and destructive for pests but mild toxic for our crops and agricultural fields.
