Adipokinetic hormone causes formation of low density lipophorin in the hemolymph of Triatoma infestans

Metabolic Post-feeding Changes in Fat Body and Hemolymph of Dipetalogaster maximus (Hemiptera:Reduviidae)

“…This is an important aspect since the low weight, low weight/ length ratio of the insect (Schofield 1980, Lehane & Schofield 1980, Schofield et al 1992), a poor nutritional status (starvation) (Sjogren & Ryckman 1966) and the need of a previous fasting period (Gringorten & Friend 1979, Ward et al 1982) have been pointed out in different species of reduviid bugs as factors stimulating flight. More recently, we demonstrated in vitro that three species of triatomine bugs have the biochemical constituents for generating partial transformation of high density lipophorin (HDLp) into low density ones (LDLp), employing fat bodies with more than 20 days of starvation (Canavoso & Rubiolo 1994, 1995. This suggests the importance of the metabolic reserve levels available in the fat body dur-ing flight.…”
