TOXICITY OF Argemone mexicana (L.) EXTRACTS AND IMIDACLOPRID ON Chrysoperla carnea (Stephens)

In sorghum (Sorghum bicolor L. Moench) cultivation, the main pest is sugarcane aphid (Melanaphis sacchari Zehntner (Hemiptera: Aphididae)). The insecticide imidacloprid frequently used to control this insect, and in some cases, it complemented with release of lacewings species Chrysoperla carnea Stephens (Neuroptera: Chrysopidae). has been shown be harmful non-target insects, such as natural enemies aphid, so necessary find other less products. objective study was evaluate toxicity aqueous oily extracts chicalote (Argemone mexicana L.) on C. contrast that imidacloprid, hypothesis A. applied developmental stages generate mortality predator than imidacloprid. had a concentration 30 g L-1. For recommended dose for (0.35 L-1) used. Mortality treatments effect were evaluated by exposure methods: T1) topical larvae, T2) egg immersion, T3) treated Sitotroga cerealella eggs, T4) liquid ingestion adults. Mortality, hatching emergence variables analyzed one-way ANOVA, followed Tukey’s comparison means (p ≤ 0.05). Treatments classified according levels proposed International Organization Biological Control. class 1 carnea, except eggs extract (class 4).
