Abstract
The efficacy examination of ethanolic and methanolic extracts from three varieties of teak (Tectona grandis L.f.) leaves, i.e., Sak-Syamindra (SS), Sak-Mahesak (SM), and Sak-Thong (ST) against larvae of diamondback moth (Plutella xylostella L., DBM) and nymph of cassava mealybug (Phenacoccus manihoti Matile-Ferrero, CMB) were investigated by using leaf dipping method. Various concentrations of extracts were applied and compared with the control (Tween-20 in water) and chemical insecticide groups. The insecticidal properties of teak extracts were studied in terms of oral toxicity test to both insects, anti-feedant activity, and inhibition of insect development assay employed to DBM and repellent test to CMB. The results presented that teak leave extract treatments gave a rather high effect in killing the larva of DBM with the median lethal concentration (LC50) at 24 and 48 hr as 7.2–8.8 and 4.9–6.4%, respectively. The methanolic extracts obtained from SM and SS at 6% concentration could inhibit the development of DBM from larva to adult, lower than 10%. Both ethanolic and methanolic extracts from ST showed the highly effective result in anti-feedant rate, at 4% concentration presented completely anti-feedant activity. For the test to CMB, the results revealed that all extracts from SM were highly effective in killing the nymph of CMB with the LC50 at 24 and 48 hr as 3.9–4.2 and 2.3–2.4%, respectively. All extracts presented a rather low effect in repellency to the nymph. The performance of insecticides against both insects showed no significant difference compared with SM extracts (p < 0.05). The results of this study implied SM extract might be another alternative way for the development of botanical insecticides.
