Insecticidal Activity of Neem, Pyrethrum and Quassia Extracts and their Mixtures Against Diamondback Moth Larvae (Plutella xylostella L.)

Original language description

The diamondback moth is known globally by many as the most destructive and economically important insect pest of cruciferous crops. It is also known to have developed resistance to numerous synthetic insecticides including those with newer active ingredients (Shelton et al. 2008); and this has triggered the development of alternative measures, including botanical insecticides (Oyedokun et al. 2011). The aim of this study was to evaluate the toxic effect of Azadirachta indica, Chrysanthemum cinerariaefolium and Quassia amara extracts and their mixtures on the diamondback moth larvae; in an attempt to find a superior mixture with more than one major active ingredient for the control of diamondback moth. The study consisted of two separate experiments; a feeding test, and a tarsal contact test. Mortality was recorded at 24, 48 and 72-h intervals from the start of the study. Varying levels of mortalities was recorded in both tests; mortalities ranged between 2-58% and 8% to 76% for the feeding test and the tarsal contact experiment respectively. In both experiments, the highest mortality was recorded in the first 24h and in formulations with the highest concentration. For the feeding test, Pyrethrins, Azadirachtin + Pyrethrins and Azadirachtin + Pyrethrins + Quassin extract/extract mixtures, produced the best effect; with Pyrethrins recording a 54% total mortality count, Azadirachtin + Pyrethrins combination producing a 48% mortality count and a 58% mortality count from Azadirachtin + Pyrethrins + Quassin extract combination. In the contact experiment, the highest mortality was observed in Pyrethrins, and Pyrethrins + Azadirachtin mixture; recording 76% and 64% mortality count respectively.
