Effects of the insecticide flupyradifurone on Anticarsia gemmatalis caterpillar and its predator Podisus nigrispinus.

The caterpillar Anticarsia gemmatalis (Lepidoptera: Noctuidae) is a prevalent pest in soybean plantations, managed using both natural and synthetic chemical products. However, the emergence of resistance in some populations emphasizes the need to explore alternative insecticides. Flupyradifurone, a neurotoxic insecticide, has not been previously used for controlling A.

Increased capture efficiency of Scolytinae with modified semi-funnel trap model.

Scolytinae species that, in high populations, can damage reducing wood production in forest crops. These beetles are monitored with traps baited with ethanol and increasing their efficiency can improve the integrated management of these insects. The objective was to evaluate the increase in the capture efficiency of Scolytinae with a semi-funnel trap model, in two experiments, one including wooden elements and other increasing the flight interception area and to correlate the numbers of these beetles collected with climatic factors.

Non-proteinaceous salivary compounds of a predatory bug cause histopathological and cytotoxic effects in prey.

N,N-dimethylaniline and 1,2,5-trithiepane, present in the salivary glands of Podisus nigrispinus Dallas (Heteroptera: Pentatomidae), are toxic compounds which kill prey. The insecticidal activity and midgut cytotoxicity in Spodoptera frugiperda (J. E.
