Abstract
Development of insecticides resistance mainly hinge with managements techniques for the control of Jassid, Amrasca biguttutla biguttutla. Five insecticides were applied against field collected and laboratory rared jassid populations during the years of 2017 to 2019 to profile their resistance level against field population of jassid through leaf dip method. Very low resistance level was found in jassid against confidor whereas high level of resistance was observed by pyriproxyfen against other test insecticides. Gradual resistance was observed against diafenthiuron. It is concluded that for the management of Jassid repetition of same insecticide should be avoided. The use of confidor may be reduced to overcome resistance against Jassid.
Highlights
Cotton (Gossypium hirsutum L.) is the most yield crop of Pakistan subsequent rice and crop of wheat and it inhabits the key portion in Pakistan linked to further crops
Selected insecticides for experiment were obtained from commercial market and corrected mortality rate were calculated from field recommended doses using Formula 1 given below
A laboratory study was conducted to check the efficacy of different concentration of insecticide (SoftStart 20SL, Confidor 200SL, Trophy 500EC, Hy-Flow 10.8EC and Pirate 360SC) against jassid (Amrasaca biguttula biguttula) in cotton crop
Summary
Cotton (Gossypium hirsutum L.) is the most yield crop of Pakistan subsequent rice and crop of wheat and it inhabits the key portion in Pakistan linked to further crops. Cotton yield produces state principal export incomes and in accumulation to the seed and lint of fiber used for the purpose of meal and fatty ingredient for 80.0% of national production oily seeds (ur Rahman et al, 2018). The cotton crop of different areas is an efficiently vital fibrous crop of Pakistan (Rehman et al, 2016). Cotton is one of the major fiber crop grown in more than 80 countries of temperate and tropical regions. Chavan et al (2010) reported 28.13 per cent avoidable yield loss due to major sucking pests in cotton. Among these whitefly and jassid is the deadliest pest and reduces the crop yield to a great extent (Alyokhin et al, 2020)
