Potentiality of Buprofezin, an insect growth regulator on the mortality of Spodoptera litura (Fabricius)

Mst Rokeya Khatun, Gopal Das and Kazi Shahanara Ahmed

Buprofezin (Award 40 SC) was evaluated at the concentrations of 200, 400 and 600 ppm on the mortality of Spodoptera litura (Fab.) larvae under laboratory conditions in Bangladesh from July 2015 to June 2016. The 2nd instar larvae were treated with selected concentrations through three different application methods viz. direct or topical, indirect or leaf-dip and combined. The larval mortality was recorded at 1, 3, 5 & 7 days after treatment (DAT) application. The mortality was clearly dose, method and time dependent. The highest larval mortality about 66.67% from combined method, 63.88% from leaf-dip and 56.70% from topical application method was recorded at 7 DAT through 600 ppm which was followed by 400 and 200 ppm respectively. Mortality increased with increasing time & at 7 DAT it was maximum which was followed by 5, 3 & 1 DAT. So from this study, it can be concluded that Buprofezin had significant effect for controlling Spodoptera litura (Fab.) larvae.
