VETERINARY ENTOMOLOGY Postlarval Fitness of Transgenic Strains of Cochliomyia hominivorax (Diptera: Calliphoridae)

چکیده
Eight transgenic strains of Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) were compared with the wild-type parental laboratory strain (P95) in colony. Measurements of average weight of pupae, percentage of adults emerging from pupae, ratio of males to total emerged adults, and mating competitiveness were analyzed. The parental strain colony was subcultured and exposed to handling procedures equivalent to transgenic strains for valid comparison of overall colony Þtness. None of the transgenic colonies exhibited signiÞcantly lower Þtness characteristics than the control parental colony. One transgenic colony had a higher ratio of adults emerging from pupae, and Þve colonies had higher average pupal weight; because Þtness cost would only be indicated by lower values, the statistical variationswerenot signiÞcant.Males of one transgenic strainwere shown tomate withequal frequencycomparedwithmalesof theparental strain.Hence, thepresenceof the transgene used to produce the strains tested did not incur a Þtness cost to the colonies of laboratory-reared C. hominivorax.

Genetically modified, mass reared insects present novel possibilities for the future of insect control. One concern about manipulation of insects is a possible loss of strain quality due to the introduction of a foreign gene of any sort into the insect genome. Eight transgenic strains of screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), were compared with the wild-type par...

Sterile insect technique (SIT) programs are designed to eradicate pest species by releasing mass-reared, sterile insects into an infested area. The first major implementation of SIT was the New World Screwworm Eradication Program, which successfully eliminated the New World screwworm (NWS), Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), from the Continental US, Mexico and much of ...

Development and utilization of transgenic New World screwworm, Cochliomyia hominivorax.
The New World screwworm (NWS), Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), was the first insect to be effectively controlled using the sterile insect technique (SIT). Recent efforts to improve SIT control of this species have centred on the development of genetically transformed strains using the piggyBac transposon vector system. Eight transgenic strains were produced incorpor...
