Does host determine short‐range flight capacity of trichogrammatids?

摘要: Biological traits, such as body size, fecundity and fertility, of egg parasitoids are strongly influenced by host species, the use a single-host species for consecutive generations has been showed to be detrimental parasitoid biology. Besides biological behaviour is also an important parameter implying their performance in field, but information about effect on still scarce. Thus, this work aimed at determining influence short-range flight capacity three Trichogrammatoidea annulata De Santis, Trichogramma atopovirilia Oatman Platner bruni Nagajara reared Anagasta kuehniella (Zeller), Corcyra cephalonica (Stainton) Sitotroga cerealella (Olivier), first, 10 28 generations. Trichogrammatids emerged inside tubular dark chamber, under controlled conditions, flying response was based proportions adults trapped sticky top chamber ones found bottom, which were checked defective wings. Our data clearly demonstrate that trichogrammatid depends fasctidious species. All had significantly reduced when from S. cerealella. The highest T. annulata registered C. cephalonica, while T. atopovirilia A. kuehniella T. bruni both C. cephalonica A. kuehniella. Parasitoid affected same over generations; however, it not possible define pattern any trichogrammatids. findings great relevance quality control mass-reared because measuring only behavioural traits with chambers can more practical less time-consuming than assessing parameters.
