摘要
The external lipids produced by adult whiteflies consisted of ''wax'' particles adhering to body hairs and of surface lipids, largely wax esters. The wax particles of each species were composed of a mixture of long chain aldehydes and long chain alcohols of the same carbon numbers, the major chain lengths being C30, C32, or C34. C34 was the dominant chain length in Aleurothrixus floccocus, Dialeurodes citri, Dialeurodes citrifolii, and Parabemisia myricae, C30 in Aleuroplatus coronata, and C32 in Aleurotithius timberlakei. The major wax esters in the cuticular surface lipids were C40 and C42 in A. timberlakei, C42 in A, coronta, C42 and C44 in A. floccosus, D. citri, and D. citrifolii, C44 in P. myricae and Aleyrodes singularis, and C46 in Aleurodicus dugesii. Other chain lengths occurred in lower proportions. Hydrocarbons, largely n-alkanes, were minor components of the surface lipids. (C) 1997 Elsevier Science Inc.
