Mermis nigrescens: Physiological relationship with its host, the adult desert locust Schistocerca gregaria

摘要: Abstract Adult desert locusts were experimentally infected per os with 30, 50, or 60 Mermis nigrescens eggs, and changes in the host physiology recorded. Larval nematodes recovered from hemocoel counted at appropriate times after infection. The food consumption blood volume of unaffected by parasitism, but nematode significantly impaired ability male to excrete injected dye, amaranth, their hemolymph. total carbohydrate hemolymph female was severely depleted during active growth period possible utilization these carbohydrates are discussed. amino acid protein levels development, although concomittant both metabolites occurred all throughout experimental period. However, this nature reflected normal pattern synthesis oocyte development oviposition control locusts, suppressed caused resorption host. did not affect level acids flight muscles a significant decrease fat body proteins recorded hosts 16 21 days effect on metabolism is discussed relation nutritional requirements involvement endocrine system.
