Abstract

The present study was carried out to analyze bioactive compounds and their antifeedant activity in the cashew nut (Anacardiaceae) shell extract against Bemisia tabaci. Hexane was used as a solvent in the extraction. The result showed that shell extract of total phenolics, flavonoids and tan-nins were 63.11 mg gallic acid equivalents g-1; 1.79mg querce-tin equivalents g−1; and 16.04 mg gallic acid equivalents g−1, re-spectively. Gas chromatography mass spectrometry (GC-MS) analyses showed that anacardic acid has the highest concentra-tion (76.93 %) in the extract. The viscous extract of cashew nut at concentration of 0.75% was able to inhibit the landing and provided an active role as anti-oviposition on B. tabaci. There were significantly fewer landings than after use of insecticide with imidacloprid active compound at concentration of 0.50 %, after 72 h of application. Mortalities of B. tabaci caused by extracts with concentration of 1.50 % and 3.00% were not sig-nificantly different after 24 and 48 h of application. At concen-tration of 3.00 % there was no phytotoxic effect. The highest mortality of B. tabaci was obtained at concentration of 6.00 %. However, concentration of 6 % of extract caused phytotoxic symptoms on soybean leaves.Key words: cashew nut
