The influences of six insect growth-regulators were evaluated on the predator Ceraeochrysacubana(Hagen) larvae and adults. Our results showed that diflubenzuron, lufenuron and pyriproxyfen caused 100% larva mortality, whereas buprofezin, methoxyfenozide and tebufenozide had been very similar to control therapy. In evaluation to the control, buprofezin lengthened the period of larval stage, while methoxyfenozide and tebufenozide decreased the predator larva development period. Buprofezin, methoxyfenozide and tebufenozide did not influence the C.cubanaduration and survival of pupal stage, fecundity and fertility. However, methoxyfenozide and tebufenozide decreased predator female and males longevities. Centered on a reduction coefficient, diflubenzuron, lufenuron and pyriproxyfen were highly harmful to very first instar larvae, while buprofezin, methoxyfenozide and tebufenozide were considered somewhat harmful to the predator. Calculating the existence table variables, our results showed that buprofezin, methoxyfenozide and tebufenozide decreased the D.cubanaR o , l and λ. In assessment to the control, buprofezin extended the Capital t and methoxyfenozide and tebufenozide shortened the predator Capital t. In adults, our results demonstrated that the insecticides do not cause significant mortality, but diflubenzuron, lufenuron and pyriproxyfen reduced the M.cubanafecundity and longevity. Diflubenzuron and lufenuron furthermore decreased the Chemical.cubanamale fertility. Centered on a decrease coefficient, diflubenzuron and lufenuron had been highly harmful to Chemical.cubanagrownups, while pyriproxyfen had been slightly dangerous and buprofezin, methoxyfenozide and tebufenozide were considered safe to the predator. Thus, insect growth-regulators impact the Chemical.cubananatural or populational variables, and they can harm the built-in pest administration applications that target the predator conservation and/or augmentation in agroecosystems.
