Field Entomology (with Pieris brassicae chemical control) Muhammad Wajid Javed, Muhammad Khurram Shahzad and Muhammad Saleem

The study was related to the chemical control of cabbage caterpillar (Pieris brassicae). The experiment was laid out in a complete randomized design (CRD) followed by five treatments with five replications to evaluate the efficacy of different insecticides against Pieris brassicae on cabbage, cauliflower and broccoli. The four synthetic insecticides ( Dimethoate 40% EC @ 400 ml /acre, Acetamiprid 20 SL @ 125 ml/acre, Profenophos 500 EC @ 400 ml/acre and Emamectin benzoate 5% EC) were used as treatment and a water as a control. The maximum percentage mortality was recorded in profenofos 77.5%,followed by emamectin benzoate 72.93%, dimethoate 72.63% and acetamiprid 58.93% respectively. So, these results showed that acetamiprid is less toxic to Pieris brassicae because it caused less mortality after 72 hours while profenophos is highly toxic because it caused 77.5 % mortality in 72 hours. While the remaining insecticides( Dimethoate 40% EC @ 400 ml /acre and Emamectin benzoate 5% EC)are less toxic than Profenofos against Pieris brassicae.
