Mating behavior of the predator Podisus nigrispinus (Heteroptera: Pentatomidae) under exposure to neem: Comportamiento de apareamiento del depredador Podisus nigrispinus (Heteroptera: Pentatomidae) expuesto al neem

The preservation of natural enemies is one of the basic foundations for integrated pest management. Botanical insecticides have shown low impact on beneficial arthropods in relation to survival. Insecticides studies usually focus on the direct physiological effects of insecticides, whereas relativel...

Azadirachtin affected the duration of first mating (Wilcoxon test, χ2 = 13.38, df = 3, p = 0.004), which resulted in a higher effective average time of mating (EATM50) for treatment whose only female was treated with azadirachtin.
