OLIVEIRA, Carlos Romero Ferreira de; MATOS, Cláudia Helena Cysneiros  and  HATANO, Eduardo. Occurrence of Pyemotes sp. on Tuta absoluta (Meyrick). Braz. arch. biol. technol. [online]. 2007, vol.50, n.6, pp. 929-932. ISSN 1516-8913.  http://dx.doi.org/10.1590/S1516-89132007000700003.

The aim of this work was to study the population reduction of the tomato leafminer moth, Tuta absoluta (Meyrick), by Pyemotes sp. in the laboratory. The mite became greenish when fed on caterpillars, pupae, and adults of T. absoluta. The caterpillars and adults of T. absoluta were quickly paralyzed by the mite venom. A single T. absoluta could host many Pyemotes sp, physogastric females, which were allowed to grow on the moth. Pyemotes sp. can be a new alternative for the biological control of T. absoluta. However, this possibility must be better understood before it could be recommended, because Pyemotes sp. could also cause dermatitis in the humans.
