Effect of fasting on the composition of the fat body lipid of dipetalogaster maximus, triatoma infestans and Panstrongylus megistus (Hemiptera: Reduviidae)
Modifications in content and lipid composition induced by fasting were examined in fat bodies from adults of Triatominae, Dipetalogaster maximus, Triatoma infestans and Panstrongylus megistus. With fasting, total lipid stores dropped approximately 50% for T. infestaris and more than 70% for P. megis...
