susceptibility of western flower thrips frankliniella occidentalis (thysanoptera: thripidae) to some synthetic and botanical insecticides under laboratory conditions
this study was conducted to investigate commercial formulations of insecticides against western flower thrips, frankliniella occidentalis (pergande).the insects were collected from commercial greenhouses of cucumber in varamin, iran. the tested insecticides were diazinon (ec 60%), cypermethrin (ec 40%), fipronil (ec 2.5%), imidacloprid (sc 35%) and a botanical insecticide oxymatrine (kingbo, as...
متن کاملThe efficacy of spinosad against the western flower thrips, Frankliniella occidentalis, and its impact on associated biological control agents on greenhouse cucumbers in southern Ontario.
Insecticides are the most commonly used tactic to control western flower thrips (WFT), Frankliniella occidentalis Pergande (Thysanoptera: Thripidae), on greenhouse cucumber. However, WFT has developed resistance to several of the insecticides presently in use. In addition, some of these insecticides adversely affect greenhouse biological control agents used to control WFT, resulting in subseque...
متن کاملInfluences of fertilization on population abundance, distribution, and control of Frankliniella occidentalis on chrysanthemum
We examined the effects of fertilization on population abundance and within-plant distribution of western flower thrips, Frankliniella occidentalis Pergande (Thysanoptera: Thripidae), on potted chrysanthemum, Dendranthema grandiflora (Tzvelev). We also investigated the effects of fertilization on the number of insecticide applications needed to control F. occidentalis on potted chrysanthemum. U...
متن کاملEffects of Exposure to High Temperature on Frankliniella Occidentalis (thysanoptera: Thripidae), under Arrhenotoky and Sexual Reproduction Conditions
Temperature plays a critical role in the population dynamics of insects. This study was designed to estimate the effect of exposure of Frankliniella occidentalis (Pergande) in the parental generation to 41 °C for various durations (2, 6, 12, 24, and 36 h) on their reproduction and on the first generation progeny. The data indicated that, under both the arrhenotoky and the sexual reproduction pa...
متن کاملEffect of reduced risk pesticides on greenhouse vegetable arthropod biological control agents.
BACKGROUND Arthropod biological control agents (BCAs) are commonly released for greenhouse vegetable insect pest management. Nevertheless, chemicals remain a necessary control tactic for certain insect pests and diseases and they can have negative impacts on BCAs. The compatibility of some formulated reduced risk insecticides (abamectin, metaflumizone and chlorantraniliprole) and fungicides (my...
