“…Cyantraniliprole was shown to be slightly toxic toward adults of E. Formosa and Bracon nigricans Szépligeti, and harmless to Tamarixia triozae (Burks) when exposed to its residues . Moreover, it did not influence the reproduction of exposed B. nigricans females .…”

“…In particular, no mortality of E. formosa adults was found on pyriproxyfen and nitenpyram residues at 5 days after treatments. Liu et al found that glass‐surface residues of abamectin caused 100% mortality of Tamarixia triozae (Burks) adults in 72 h . Similarly, Fernández et al reported that aged insecticide residues were less toxic to natural enemies than fresh residues .…”

“…The residual effects of insecticides on survival and parasitism of E. formosa were assessed at different time intervals after insecticide treatments following the methods of Liu et al Healthy potted tomato plants were sprayed with the tested insecticides at field‐recommended concentrations (Table ) and kept at 26 ± 1 °C, 60 ± 5% RH and L14: D10 photoperiod. Tomato leaves of 0 (sampled at 1 h), 1, 3, 5 and 7 days after spray were excised at the petiole using a sterilized scissors and immediately wrapped with cotton and inserted into a 60‐mL cup filled with distilled water .…”

BACKGROUND Encarsia formosa Gahan is the most important parasitoid exploited for the control of whitefly pests of vegetable crops. However, the non‐target effects of recently developed insecticides for controlling whiteflies toward this biocontrol agent is little documented. Here we evaluated the susceptibility of E. formosa adults and juveniles to eight commonly used insecticides against whiteflies. RESULTS Residual toxicity tests on glass showed that E. formosa adults were susceptible (over 98% mortality after 6 h treated) to field concentrations of the tested neonicotinoids (imidacloprid, acetamiprid, nitenpyram and thiamethoxam), abamectin, cyantraniliprole, and sulfoxaflor at their field concentrations. Pyriproxyfen was harmless to both adult and pupae of E. formosa. A risk quotient analysis showed that toxicity of pyriproxyfen to E. formosa adults was the lowest, followed by acetamiprid and cyantraniliprole. In the leaf residues test, mortality of E. formosa adults under all insecticides decreased when the residue age increased. Interestingly, E. formosa experiencing contact with the residues of most insecticides, except pyriproxyfen and abamectin, parasitized significantly more hosts 5‐days after treatment, suggesting a hormetic effect on parasitism. CONCLUSION The risk assessment of insecticides indicated that pyriproxyfen and cyantraniliprole were the least toxic to E. formosa. Our results suggest that the inclusion of the insecticides in sustainable integrated pest management programs of whiteflies should be carefully evaluated on a case‐by‐case basis. © 2019 Society of Chemical Industry

To control Bemisia tabaci on tomato, we applied five different combinations of chemical treatments as below: 1) treatment of combinations of cyantraniliprole on the root area and leaf with the existing registered chemicals three times; 2) treatment of combinations of cyantraniliprole on the root area and dinotefuran + emamectin benzoate on the leaf with the existing registered chemicals three times; 3) treatment of combinations of dinotefuran on the root area and cyantraniliprole on the leaf with the existing registered chemicals three times; 4) treatment of combinations of dinotefuran on the root area and dinotefuran + emamectin benzoate on the leaf with the existing registered chemicals three times; 5) untreated control plot (Table 1). Twenty days after treatment (17 t h Aug.), the number of population of B. tabaci was zero on the 1, 2, 3, 4 treatments of combinations, and only 2 individuals were found on the 5 treatment of combination per each 20 plant. On 17 t h Sep., in the last observation, the average number of population of B. tabaci was 10.3, 10.3, 10.6 on the 1, 2, 3 treatments of combinations on the 20 plants per each combination, however, the average number of 23.3 and 37.6 were examined on the 4 and 5 treatments of combinations, respectively. TYLCV was not occurring on the 1 and 2 treatments of combinations, and presented only 3% and 17% on the 3 and 4 treatments of combinations, respectively, which indicates that the treatments (1-4) should be effective on TYLCV control as considering that 33% of TYLCV occurred on the untreated control plot. However, after the third flowering period, there is no difference among the five combinations. The amount of products was 9,148g and 9,698g on the 1 and 2 treatments of combinations, respectively, which was the most among the 5 combinations. The number of fallen fruits and the average weight of fruits showed the similar tendency.
