Abstract :

Termites are one of the most important insect pests in many countries of the world such as Iran. The use of Insect growth regulators (IGRs) together with entomopathogenic fungi is one of the strategies of IPM against these pests. In this study, The effect pyriproxyfen  with M. anisopliae was assayed on worker termite of Amitermes vilis. In order to determine the LC50 of insecticides, bioassay tests were carried out on  worker termites. The LC50 of M. anisopliae was 8.5× 103 spores/ml and LC50 for pyriproxyfen was 9.56  mg/L. Three concentrations of entomopathogenic fungus including 5× 101, 5× 102 and 103 spores/ml were mixed with LC15 (0.5 ppm) of pyriproxyfen. The bioassay of the three mixtures on worker termites showed that M. anisopliae and pyriproxyfen had  an additive interaction and the mixture of fungi concentrations with pyriproxyfen can be used for termite control.
