The selectivity of entomopathogenic fungi to non-target organisms needs to be considered in Integrated Pest Management (IPM), because even though they are biological control agents, if used incorrectly, they can negatively alter the functioning of agroecosystems. Therefore, studies that assess the selectivity of these fungi to beneficial organisms are extremely important. The objective of this work was to evalu...
Augmentative biological control (ABC) of insect pests is an environmentally sustainable alternative to synthetic insecticides. By performing BC, more than one control agent can be used for the same insect pest that is in different stages of its life cycle or for pests that simultaneously occur in the area. However, this relationship requires biosecurity for the control agents employed. The aim of this study was...
Chrysodeixis includens Walker, 1858 (Lepidoptera: Noctuidae), commonly known as soybean looper, is one of the main pests that reduces soybean yield due to its defoliation capacity. Population outbreaks of this pest can occur in the vegetative stage of the crop, together with the occurrence of weeds or in the reproductive stage, at the same time as that of diseases. This often requires the use of pesticides agai...
Foi estudada a capacidade de parasitismo de Trichogramma acacioi em ovos de Anagasta kuehniella e Sitotroga cerealella em diferentes temperaturas (15, 20, 25, 30 e 35 ± 1°C). O parasitismo de T. acacioi variou com a temperatura e hospedeiro. O maior parasitismo (³80%) foi observado durante os primeiros dias após a emergência, em ambos hospedeiros e em todas as temperaturas estudadas. O parasitismo acumulado var...

The present study evaluated the effect of different rates of chlorantraniliprole, chlorantraniliprole + lambda-cyhalothrin, spinosad, and chlorfenapyr on their selectivity for the pupae and adults of Trichogramma pretiosum. The negative effect of majority of the insecticides tested on most of the parasitoids was directly proportional to the rate of the insecticide applied. Chlorantraniliprole at a rate of 10 g ...
Soybean plants host a diverse complex of pest insects, which can occur simultaneously during crop development. Thus, the use of egg parasitoids for the management of Euschistus heros (Fabricius) (Hemiptera: Pentatomidae) depends on the selectivity of the pesticides to the stink bug. Thus, the selectivity of the active ingredients chlorantraniliprole and chlorantraniliprole + lambda-cyhalothrin to the parasitoid...
