  Field studies were carried out to evaluate the effects of different insecticides as foliar application for the control of aphids population on canola (Brassica napus L.) crop. The insecticides Endosulfan (Thiodan 35EC), Fenpropathrin (Sanitol 20EC) and Dimethoate (Systoate 40EC) were sprayed with knapsack sprayer at the normal recommended doses and a check plot was also maintained for comparison. The efficacy of these insecticides was assessed by counting the aphids mortality and their influences on grain yield on treated plots. Studies revealed that all the tested insecticides were superior and most promising for aphids management and provided better crop yield as compared to untreated plot (140 aphids per plant and 1707 g yield per 8m2). Endosulfan was proved highly toxic to control aphids population (4.66 aphids plant-1) and maximum yield was obtained (2322.0 g/8m2) followed by Fenpropathrin and Dimethoate (6.83, 13.17 aphids plant-1 and 2107.0, 1948.0 g/8m2 grain yield, respectively).

  Field experiment was conducted to test a synthetic insecticide and insecticidal properties of four selected plant origin materials at the experimental farm, NIA, Tandojam. Insecticidal effects of these products were assessed against Helicoverpa species on chickpea crop and compared with control. After treatment, counts for larval mortality and percentage pods infestation were made at 24 and 72 h intervals. Our experimental results showed that over all pods infestation percentage and seed yield in treated plots were significantly higher than the untreated plots. However, as it is evident from the data the synthetic product gave the best results than all the sets of natural products for the parameters studies.

  Eight chickpea genotypes were evaluated against the infestation of Helicoverpa species under the field conditions at NIA, Tandojam. Helicoverpa species were the most serious insect pests causing severe damage to this crop. In order to identify resistance against the infestation of this pest, seeds of the test genotypes were obtained from Plant Genetics Division of this Institute. Results depicted that all the genotypes showed varied response to the traits under observation. The data on larval population, percentage damage and yield components was highly variable, showing the percentage larval attack severity 1.00 to 50.00, pods damage 8.50 to 90.90% and 23.33 to 1920.00 gm grain yield of the sampling unit. Data revealed that genotype C-727 was relatively resistant against pod borer infestation as compared to other genotypes.
