“…These data suggest that the product had a deleterious effect on the survival of IJs. Koppenhöfer and Fuzy (2008) observed a negative effect of products belonging to the group of anthranilic diamides, a group to which cyantraniliprole belongs, on the viability of EPNs. The authors found that chlorantraniliprole was compatible with the nematode H. bacteriophora when exposed to a tank mix and observed that the combination of the nematode with the product led to high mortality of choroidal larvae, indicating an additive or synergism effect between them.…”

Attack by the coffee berry borer Hypothenemus hampei causes significant damage to coffee crops because it affects the quality of the coffee fruit during different developmental stages, which results in production losses. Control of the borer is difficult owing to its cryptic behavior and the fact that it spends its entire life cycle inside the coffee berries. This makes it difficult for natural enemies to reach it, as well as for it to come into contact with chemical insecticides. The objective of the present study was to select and evaluate the virulence of entomopathogenic nematodes (EPNs) on the coffee berry borer H. hampei and their compatibility with the insecticide cyantraniliprole under laboratory conditions. Initially, the pathogenicity and virulence of 16 isolates of Steinernema and Heterorhabditis towards coffee berry borer larvae and adults were evaluated. The most virulent isolates to both larvae and adults were determined by topical inoculation tests in coffee fruits (berries) infested by the insect, using a concentration of 100 infective juveniles (IJs)/fruit. The same isolates were also evaluated for viability and infectivity when combined with cyantraniliprole. The isolates S. feltiae (IBCB-n 47) and Heterorhabditis amazonensis (GL) displayed the highest virulence towards adults (54% ResumoA broca-do-café Hypothenemus hampei causa significativos prejuízos a esta cultura, pois seu ataque afeta a qualidade dos frutos de café em seus diferentes estádios de desenvolvimento e consequentemente leva a perdas na produção. O controle é dificultado devido ao seu comportamento críptico, uma vez que passa todo o ciclo dentro dos frutos de café, dificultando a ação de inimigos naturais, bem como o contato com inseticidas químicos. O objetivo deste estudo foi avaliar a virulência de nematoides entomopatogênicos (NEPs) sobre a broca-do-café H. hampei e a sua compatibilidade com o inseticida ciantraniliprole em condições de laboratório. Inicialmente, foram avaliadas a patogenicidade e virulência de 16 isolados de Steinernema e Heterorhabditis para larvas e adultos de H. hampei. Os isolados mais virulentos para larvas e adultos foram utilizados no teste de inoculação tópica em frutos de café infestados pelo inseto, utilizando uma concentração de 100 juvenis infectantes (JIs)

A rapid, highly sensitive, and selective method was developed for the determination of the insecticide chlorantraniliprole (CAP) in corn and soil using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Samples were extracted with acetonitrile, and aliquots were cleaned with solid-phase extraction cartridges. Two precursor-product ion transitions for CAP were measured and evaluated to provide maximum confidence in the results. Average recovery for soil, corn grain, and corn straw at different levels (5 or 10, 40, and 100 lg kg -1 ) ranged from 74.9 to 97.5%, with intra-day relative standard deviation (RSD) values of 1.9-11.3% and inter-day RSD values of 4.7-10.4%. Coefficients of determination (R 2 ) of 0.9988 or higher were achieved for CAP in soil, corn grain, and corn straw matrix calibration curves, from 5 to 1,000 lg L -1 . The CAP limits of quantitation in soil, corn grain, and straw were determined to be 5, 10, and 10 lg kg -1 , respectively, which were much lower than the maximum residue levels established by the Environmental Protection Agency of United States. UPLC-MS/MS was used to determine the CAP residues in real corn and soil for studies on their dissipation. The trial results showed that the half-lives of CAP changed from 12.6 to 23.1 days in soils and ranged from 4.9 to 5.4 days in corn straws in the districts of Henan and Shandong, and the average levels of CAP residues in corn grains were all \0.01 mg kg -1 with a harvest withholding period of 180 days.

“…Although compatibility of numerous insecticides with EPNs has been studied in the laboratory (Koppenhöfer and Fuzy 2008;Negrisoli et al 2010), the control efficiency of combined application of EPNs with Field evaluation of entomopathogenic nematodes certain chemical insecticides in the field needs to be further studied. Laboratory assays indicated that azadirachtin causes no direct harm to EPNs (unpublished results).…”

The striped flea beetle, Phyllotreta striolata (F.) (Coleoptera: Chrysomelidae) is a key pest of crucifer vegetables in Southern China. The use of entomopathogenic nematodes (EPNs) within an integrated pest management approach may offer an effective and environmentally safe strategy to suppress outbreaks of this pest. In the present study, the efficacy of Steinernema carpocapsae All and Heterorhabditis indica LN2 for the control of P. striolata in the field was evaluated, as well as the combined application of EPNs and azadirachtin against the pest. Both nematode species were capable of reducing populations of the soil-dwelling stages of P. striolata, thus leading to a reduction of the adult populations and the associated shot-hole damage on the leaves. Nematode treatments also increased cabbage yields as compared to the control and azadirachtin treatments alone. Azadirachtin alone was not effective to prevent damage by P. striolata, but it could enhance the control effect of S. carpocapsae shortly after application. Osmotically treated infective juveniles (IJs) of S. carpocapsae All performed as well as untreated IJs.
