abstract
Spider mites are very notorious, polyphagous, cosmopolitan and economically important pest of vegetables, fruits and various other agricultural crops. They may cause discoloration, curling, yellowing and also webbing on the leaves, which ultimately reduced the yield. Hence the present study was carried out to determine the effectiveness of the four insecticides against spider mites. Brinjal crop was sown in the Research area of Department of Entomology, University of agriculture Faisalabad by using (RCBD) with four replications. Pretreatment data were taken and post treatment data were also recorded after 1, 3, and 7 days after spraying the insecticides. At the end of the experiment data was analyzed by analysis of variance (ANOVA) and means were compared by using LSD test at 0.05, level by using Statistix 8.1 software. After the application of insecticides results showed that all the treatments had almost similar impact on reducing the population of red spider mites but all insecticides showed a clear significant result as compared to control where maximum population of red spider mites (13.10 mites per leaf) observed. Among the insecticides minimum population of red spider mites was recorded in the plots treated with Chlorfenypyr 10%EC with 0.43 mites per leaf which followed by remaining other three treatments Abamactin+spiromesifen 2.5%EC , Fenoxypyroximate 5%SC and Abamactin 1.8%EC with 0.57 mites per leaf, 0.72 mites per leaf and 1.22 mites per leaf respectively. Also maximum No of fruits per plants (6.45 fruits per plant) were recorded from the plots treated with Chlorfenypyr 10%EC while minimum No of fruits were recorded from control treatment. But the impact of red spider mites on average weight and average size of fruits was Non-significant.
