Nesidiocoris tenuis (Reuter, 1895) (Hemiptera: Miridae) is the most widely used biological control agent of tomato pests, particularly leafminer. Five treatments, spinetoram, chlorantraniliprole + abamectin, thiamethoxam, emamectin benzoate and dimethoate were tested on N. under greenhouse conditions in summer autumn 2018 Malatya Province, Turkey. After insecticide application, counted days 1, ...

The impact of commonly used organophosphate (chlorpyrifos, methamidophos), carbamate (carbaryl), and pyrethroid (cypermethrin) insecticides on insect natural enemies was compared with that of a nucleopolyhedrovirus (Baculoviridae) of Spodoptera frugiperda (J. E. Smith) (Lepidoptera Noctuidae) in maize grown in southern Mexico. Analyses of the SELECTV and Koppert Side Effects (IOBC) databases on...

Spinosad† (Dow Agrosciences) is a neurotoxic insecticide produced by fermentation of an actinomycete. Spinosad is classified as an environmentally and toxicologically reduced risk material and has been embraced by IPM practitioners as a biorational pesticide. We examined the available information on the impact of spinosad on natural enemies and classified mortality responses to spinosad using t...

Experiments were carried out on the toxicity of selected insecticides and fungicides to the predatory mites species: Amblyseius swirskii, A. andersoni, and Phytoseiulus persimilis. Among the tested active substances: abamectin, hexytiazox, and spinosad were safe to the predators. The mortality level of the tested predator was comparable to the control treatment, seven days after application. Th...

Aim of study: Assessment toxicity and sublethal effects registered insecticides currently used in strawberry cultivation Brazil on Trichogramma pretiosum Riley adults.Area The study was conducted under laboratory conditions Paraná (Brazil).Material methods: Previously non-parasitized Duponchelia fovealis Zeller (Lepidoptera: Cambridae) eggs were dipped into insecticide dilutions or control solu...

The toxicity of three insecticides to Lysiphlebus fabarum (Marshall) (Hymenoptera: Braconidae: Aphidiinae), a parasitoid of Aphis fabae Scopoli (Hemiptera: Aphididae), was investigated using IOBC/wprs protocols. Abamectin 1.8 EC, imidacloprid 350 SC, and pymetrozine 25 WP were tested under laboratory conditions at recommended field rates. Immature stages of the parasitoid were exposed to materi...

Temperate fruit crops are an important economic activity for growers in southern Brazil. However, several pest species are associated to apple (Malus domestica Borkh.) crops in Brazil. Pesticides are largely used to control them and one way to change this is to combine selective pesticides and predator insects. The goal of this research was to evaluate the effects of the abamectin, carbaryl, fe...

Abstract In many cases, pesticides’ side effects on natural enemies have closely related to their exposure route. We assessed long-term lethal and sublethal of thiamethoxam (TMX) the predatory bug, Orius albidipennis (Reuter), fed Aphis gossypii Glover (Hemiptera: Aphididae), through three routes. First-instar nymphs were treated with maximum field recommended concentration (MFRC), ½ MFRC, ¼ MF...
