Microbial pesticides can be significantly improved by adjuvants. At present, microbial pesticide formulations are mainly wettable powders and suspension concentrations, which usually produced with adjuvants such as surfactants, carriers, protective agents, nutritional Surfactants improve the tension between liquid crop surfaces, resulting in stronger permeability wettability of formulations. Carriers inert components loaded or diluted pesticides, control release active at appropriate times. Protective agents able to help microorganisms resist adverse environments. Nutritional used provide nutrients for pesticides. Most still refer those chemical However, some may have harmful effects on non-target organisms ecological Herein, order promote research improvement types were briefly reviewed, progress their applications highlighted, challenges future perspectives towards sustainable green also discussed this review.

Pesticides can be noxious to non-target beneficial arthropods and their negative effects have been recently recognized even at low doses. The predator Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) plays an important role in controlling insect pests solanaceous crops, but its concurrent herbivory often poses relevant concerns for tomato production. Although insecticide side on N. previously studied, little is known the potential implications of neurotoxic chemicals concentrations. We assessed baseline toxicity three insecticides (lambda-cyhalothrin, spinosad chlorpyrifos) by topical contact exposure. behavioral reproduction capacity was then investigated upon exposure estimated low-lethal concentrations (LC

Abstract Zoophytophagous hemipteran predators provide relevant biological control services and their applications are consolidated in greenhouse pest management. The use of plant essential oils (EOs) for sustainable crop protection is being currently promoted. However, further knowledge the potential side effects EOs on predatory mirids (Hemiptera: Miridae) required. Here, we evaluated non-target impact four (anise, fennel, garlic lavender) generalist predator Nesidiocoris tenuis (Reuter) laboratory. baseline toxicity was firstly assessed N. adults following topical contact exposure. Then, reproduction orientation behavior tested exposure to three estimated EO lethal concentrations (LC 1 , LC 10 30 ). Garlic had lowest LCs (e.g., 1.34 mg mL −1 ), thus most toxic compound among EOs. s lavender, anise fennel were 2.75, 4.55 5.17 respectively. fertility females negatively affected by all at highest concentration. Nevertheless, caused no sublethal . Our findings suggest that careful attention should be given when used combination with management programs.

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a major threat to worldwide tomato production, and sustainable management methods are needed. Betabaculovirus phoperculellae (PhopGV) the parasitoid wasp Necremnus tutae Ribes & Bernardo (Hymenoptera: Eulophidae) were identified as promising biocontrol agents of this pest. Since virus most effective against first instar larvae, whereas targets older ones, combining both could result in increased pest control. We conducted replicated semi-field experiment evaluate control efficacy N. PhopGV when used alone combination T. their compatibility over an entire growth period. Combining two achieved highest larval (−24 %) crop damage (−29 reduction cumulated experiment. However, there was no significant additive effect agents. At end trial, which coincided with emergence third generation adults, using resulted strongest adult density (−78 %), followed by virus-parasitoid (−59 %). No negative recorded on population. Our results demonstrate potential reduce population under conditions. While more research needed, our findings provide important insights into innovative agents, thereby contributing agriculture.
