Severe incidence of an exotic whitefly species Paraleyrodes mineiIaccarino (Homoptera: Aleyrodidae) was noticed in the Pune region of Maharashtra state, India, on the fruit trees guava (Psidium guajavaL.), jamoon (Syzygium cuminiL.), mango (Mangifera indicaL.), chiku (Manilkara zapotaL.), custard apple (Annona squamosaL.), citrus (Citrus spp.), banana (Musa spp.) and coconut (Cocos nucifera L.). Additional host plants of P. mineiare neem (Azadirachta indicaL.), Asoka (Saraca asoca(Roxb.) and temple tree (Plumeria albaL.). The identity of the pest was established based on sequences of the mitochondrial cytochrome oxidase 1 (mtCO-I) region amplified from genomic DNA of single whitefly. The incidence of P. mineiwas 100% on guava, jamoon, and custard apple; wherein under the surface of the infested leaves looks completely white with cottony wax. In the case of, coconut, guava, chiku, and banana, P. mineiwas co-colonising along with the rugose spiralling whitefly (Aleurodicus rugioperculatusMartin). Star gooseberry (Phyllanthus acidusL., new host record) plants were severely infested with less frequently collected whitefly, Bemisia bryniae (Singh). Pomegranate (Punica granatumL.) was infested by whitefly Siphoninus phillyreae(Haliday). The study highlights the need for continuous monitoring of invasive whitefly species population on important fruit crops for timely application of management practices to prevent losses of potential yield. |
