Mealybugs Ferrisia virgata (Hemiptera: Pseudococcidae) are the one of the noxious sucking insect pest infesting horticulture crops including tomatoes. Efficacy of botanical extracts of bird chili Capsicum frutescens L., garlic, Allium sativum L., black pepper Piper nigrum L., and neem, Azadirachta indica was investigated on F. virgata at the Entomology Laboratory, Suranaree University of Technology, under an ambient temperature of 27 ± 2 ◦C, and relative humidity 60 – 70%. The plant extracts at concentrations 0.2, 0.5 and 1.0 % were applied for tomato and over the mealybugs.Experiment was arranged in a completely randomized design in four replicates. All plant extracts at the highest concentration of 1.0% showed the highest percentage mortality (100%) at 48 hours after an exposure. All concentrations at 24 hours after an exposure, Az. indica extract had significantly reduced (P<0.05) mealybugs population followed by P. nigrum, C. frutescens and Al. sativum. The results reveal that extracts from the three botanical plants (Az. indica, P. Nigrum, C.frutescens) are effective in controlling F. virgata and could serve as an alternative to synthetic insecticides.
