“…Recently, an increasing number of new insecticides have been developed and applied in IPM programs for the control of whitefly, and they are expected to be safe for biocontrol agents of these pests. 20,[45][46][47] However, E. formosa often exhibits greater susceptibility to insecticides than its hosts. 44,48 In our study, significant differences were found among the toxicities of eight insecticides at their recommended field concentrations to E. formosa adults under laboratory conditions.…”

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

“…Flonicamid is a novel systemic insecticide that belongs to pyridinecarboxamide group and acts as irreversible inhibitor of aphid feeding (Roditakis et al, 2014). This compound was discovered by Ishihara Sangyo Kaisha, Ltd., Japan and launched in many parts of the world such as USA, Brazil, France and Korea Since 2005 (Morita et al, 2007).…”

Pyridinecarboxamide and neonicotinoids insecticides are used in small quantity and economically effective for control sucking pests in cotton fields. Therefore, the current study was conducted to evaluate the efficiency of flonicamid, imidacloprid and dinotefuran and its compared with abamectin, carbosulfan, malathion and cholorpyrifos against cotton aphids, Aphis gossypii Glover and whitefly, Bemisia tabaci (Genn.) and its associated predators, Chrysoperle carnea (larvae and adults) and spiders in cotton fields at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate, Egypt during 2017 and 2018 cotton seasons. Seven insecticides were applied at their field recommended rates. The obtained results proved that imidacloprid, flonicamid and dinotefuran were recorded the highest mean reduction of aphids (92.95, 86.36 and 76.16%) at 2017 and (90.95, 82.48 and 78.44%) at 2018 season. Carbosulfan and chlorpyrifos caused moderate effective against Aphis gossypii, while the least effective compound was malathion. Concerning the whitefly, imidacloprid, flonicamid and dinotefuran statistically exhibited reduction in populations of adults' stage ranged from 67.54-78.46% in 2017 and 2018 seasons and 71.04-87.26% reduction in immature stages in both seasons, while carbosulfan was the least effective compound against Bemisia tabaci (adult and immature stages). It is important to note that flonicamid, imidacloprid and dinotefuran were less harmful effect on populations of tested predators than the tested organophosphates and cabosulfan. Accordingly, flonicamid, imidacloprid and dinotefuran are useful choice for use in IPM programs to control these pests in cotton fields.

“…Flonicamid, a pyridine carboxamide, is a novel insecticide that is in the selective Hemiptera‐feeding blocker group (mode of action group 9C; classification by IRAC, http://irac-online.org). The insecticidal mechanism appears to be starvation caused by irreversible inhibition of feeding activity . Flonicamid inhibits the feeding activity of insects immediately after treatment and is an effective insecticide against sap‐sucking insects such as whiteflies, aphids, leafhoppers (jassids), thrips, scales and mealybugs .…”

Activity of flonicamid on the sweet potato whitely Bemisia tabaci (Homoptera: Aleyrodidae) and its natural enemies

Abstract: Flonicamid is an effective tool for the management of B. tabaci populations from Crete, and initial studies indicate that it could be combined with B. tabaci natural enemies.
