water pan trap - Opis:
- Alatae of seven aphid species viz., Aphis gossypii Glover, Lipaphis erysimi (Kaltenbach), Macrosiphoniella sanborni (Gillette), Myzus persicae (Sulzer), Neomyzus circumflexus (Buckton), Pentalonia nigronervosa (Coquerel) & Rhopalosiphum maidis (Fitch) are sampled during August, 2017 – March, 2018 using yellow, green and red water pan traps placed at Narendrapur and Dumdum, Kolkata. Total no. of species and alate individuals are found to vary between sites and trap colour. Yellow is found to be the most preferred colour (no. of alatae: 1080). Among the seven species trapped, Aphis gossypii alatae dominate over rest of the species. All the seven species are supposed to be invasive ones to crops. From late September alate aphids initiate migration from subtropical regions to plains and continue till March. It is felt that early sowing of the winter crop/flowering plants may avoid pest aphid incidence.
