| waxes and lipids associated with the external waxy structures of nymphs and pupae of the giant whitefly, aleurodicus dugesii. | the nymphs and pupae of the giant whitefly, aleurodicus dugesii, produce large quantities of external lipids, both as waxy particles and as waxy filaments. the nymphs and pupae extrude filaments from two dorsal rows of five pores each. filaments can attain lengths of 5-8 cm. the external lipids of nymphs and pupae consist largely of long-chain aldehydes, alcohols, acetate esters and wax esters. hydrocarbons are minor components. soon after hatching, the nymph produced an unidentified waxy fringe ... | 2000 | 10817914 |
