Efficacy of herbal extracts and synthetic compounds against strawberry thrips, Frankliniella occidentalis (Pergande) under greenhouse conditions

Gholamreza Golmohammadi and Ali Mohammadipour

The western flower thrips, Frankliniella occidentalis (Pergande), is a serious pest of greenhouse crops that has short generation and high fecundity. This experiment was conducted based on a completely randomized design with seven treatments and four replications in the greenhouses of Varamin (Tehran province) and Karaj (Alborz province). The treatments were as follows: flonicamid, dichlorvos, azadirachtin, pyrethrum and control (water spray). In Tehran, the efficacy persents, 3 days after treatment, were 82.35±3.45 (flonicamid at 300 ppm), 87.03±2.67 (dichlorvos at 1000 ppm), 69.35±3.85 (flonicamid at 250 ppm), 68.53±4.46% (flonicamid at 200 ppm), 56.95±5.27 (azadirachtin at 2500 ppm) and 55.94±4.62 (pyrethrum at 4000 ppm). Seven days after treatment, the highest and lowest efficacies were 85.75±2.17 (flonicamid 300) and 66.37±3.22 (azadirachtin). In Karaj, three days after treatment, the efficacies were 80.46±3.65 (flonicamid 300), 70.46±3.45 (flonicamid 250), 75.38±4.27 (flonicamid 200), 82.14±2.25 (dichlorvos), 61.39±3.52 (azadirachtin) and 47.42±2.14 (pyrethrum). In general, the herbal extracts and the new insecticide, flonicamid, had acceptable control against Strawberry thrips in the greenhouse.
