Impact of Plant Extracts of Embelia ribes and two Commercial Pesticides on Mortality and Predator Activity of a Generalist Predator, Oxyopes lineatipes

Original language description

Even as new substances show promise as biopesticides for controlling pests due to their natural properties and high effectiveness in inhibiting pests, their side effects on nontarget organisms must nevertheless be evaluated before they can be included into integrated pest management systems. In this study, a crude extract from dried leaves of Embelia ribes was evaluated together with two commercial pesticides: azadirachtin and amitraz. We examined both lethal and sublethal effects on the predatory potential of the lynx spider Oxyopes lineatipes. We found that the spider&apos;s mortality increased with rising concentration of both commercial products, azadirachtin and amitraz, but not with rising concentration of the extracts from E. ribes. The greatest mortality occurred when amitraz was used. Azadirachtin significantly reduced the rate at which O. lineatipes captured prey while there was no significant difference in capture rates among spiders exposed to a control treatment and the E. ribes treatment. Considering its absence of unfavorable impacts on O. lineatipes in terms of mortality and predatory activity, the plant extract shows promise as a new biopesticide material. In contrast, azadirachtin, which has been considered as safe for nontarget organisms, exhibited slight lethal effect and strong sublethal effect by reducing spiders&apos; predation rate.
