First record of galls in hog plum (Spondias mombim L.) panicles caused by Clinodiplosis (Diptera: Cecidomyiidae) and evaluation of genotypes in Piauí State

Hog plum (Spondias mombim L.) is an Anacardiaceae of considerable social and economical importance in Brazilian northeast. Various authors mentioned insects that affect leaves, branches and the fruits, but information related to flower pestsis limited. Cecidomyiidae is a very well diversified family of Nematocera (Diptera). Cecidomyinae has varied habits and a great variety of phytophagaus species. This study had as objective the identification of a galling Cecidomyiinae species, characterization of the attack symptoms and assess the level of infestation of this species in panicles of different hog plum genotypes. The experiment was developed in a hog plum orchard from the Departamento de Fitotecnia from Universidade Federal do Piauí. Eight genotypes were evaluated: JL 15, LA 1, Fazenda Soares I, Fazenda Soares II, Fazenda Soares III, Major, Vagner and Jardim. The insect was identified as Clinodiplosis sp. Considering the high specificity of galling Cecidomyiinae (Clinodiplosini) with respect to host plants, the Clinodiplosis species associated with Spondias mombim is probably new. The genotypes Major, LA 1, Soares I and Jardim showed lower infestation. The genotypes JL 15, Vagner, Soares III and Soares II showed the highest infestation. These results show that the level of infestation by Clinodiplosis sp varies with the hog plum genotype assessed.
