HIGHLIGHTS

• who: baicu from the Laboratory bioassay was tested against Varroa mites of honeybeesThe experiment was tried on five Varroa mites (Varroa destructors). Fumigation technique was used in all approach. Collection of data was carried out at different time interval after application of different concentrations of plant extracts during bioassay testing of the mites. The population of pests were noted and recorded after each plant extract applications. Biopesticidal activity of , plant extracts was performed using adult fumigation test according to (Drummond et_al, ). Serial dilutions of plants extracts oils (25%, % and, %) were prepared in distilled water. Antipest effects of . . .
