摘要

Insect pests being documented for many agricultural and horticultural crops are of global concern for controlling and minimizing damage potential. To record bio-invasion of pests and recognize their potential biological control agents, accurate pest identification often challenges taxonomic expertise due to morphological variations or phenotypic plasticity. Whiteflies (Hemiptera: Aleyrodidae) are one among the sucking pests that show phenotypic plasticity depending on the host plant cuticle on whichthey develop, which resulted in several species synonymies in past. The variable morphology of the immobile fourth nymphal instar or 'pupal case', the stage which is used for identification, causes difficult circumstances for whitefly identification. Among the 1559 described species under 161 genera in the world, the whiteflies Aleurolobus marlatti (Quaintance), Bemisia tobaci (Gennadius) and Trialeurodes vapomriorum (Westwood) are polyphagous and show host-associated variations. Host-correlated variations in puparial morphology may have evolved for concealment from natural enemies, thus providing survival success to species. Host specificity is not obvious in aleyrodids, but so far recorded variations are from polyphagous species. The spiraling
