The waste artificial larval rearing media of New World screwworms, Cochliomyia hominivorax (Coquerel) were evaluated to determine their effectiveness as oviposition attractants. Various concentrations of waste larval media resulting from rearing screwworm larvae in gel and cellulose fiber-based artificial diets tested over a 4-wk period attracted varying number of gravid screwworm flies to ovip...

I present the first behavioural study of natural populations of a Madagascan poison frog. Focal watches of marked individuals were conducted for 925 h, in five populations, across two seasons. Like the New World dendrobatids, these diurnal anurans eat ants and are aposematically coloured. Data are presented that provide additional instances of convergence with the dendrobatids, including (1) ex...

Anopheles gambiae complex mosquitoes comprise different morphologically identical species and the most medically important malaria vectors in Africa. Understanding An. mosquitoes’ mating behaviour is a clue for prevention control of malaria. The factors affecting behavior are age, body size, food finding, type food, host availability environmental temperature. passes through unique strategies. ...

Oviposition is induced upon mating in most insects. Ovulation is a primary step in oviposition, representing an important target to control insect pests and vectors, but limited information is available on the underlying mechanism. Here we report that the beta adrenergic-like octopamine receptor Octβ2R serves as a key signaling molecule for ovulation and recruits protein kinase A and Ca(2+)/cal...

An intravenous injection of arginine vasotocin (AVT) at 16 h before the expected oviposition of the initial egg of an egg-laying sequence caused bearing down for oviposition. Oviposition was increased up to 100% by increasing the dose of AVT up to 1 microg, but it decreased when the dose was 10 and 20 microg. Bearing down was observed even when the oviposition was not induced by the injection o...
