Effect of leucokinin ii as neuropeptide hormone on some biological aspects of two lepidopteran larvae [electronic resource].

Includes reference.

The insect kinin neuropeptides are a large family that shares the cornmon C-tenninal pentapeptide (phe -Xaa'-Xaa'- Trp- Gly-NH2 (Xaa1= His, Asp, Phe. Ser. or Tyr; Xaa2= SeT, pro, Ala) and has been isolated from such diverse sources as the cockroach Leucophaea maderae, (Holman et aL., 1987), cricket Aceta domesticus, locust Locusta migratoria (Holman et al., 1990) and the mosquitos Culex salinarius, (Hayes et al., 1994). Aedes aegypti, (Veenstra, 1994) as well as the com earwom Helicoverpa zea (Blackburn et al., 1995). Insect kinins regulate water and mineral balance as well as digestive process. Nevertheless, insect neuropeptides themselves hold a promise as insect control agents (Nachman and Holman, 1991).
