Electromechanical microinjection of pink bollworm Pectinophora gossypiella embryos increases survival.
We report and compare methods and apparatus for injection of pink bollworm, Pectinophora gossypiella (Saunders), embryos. Injection with an electromechanical device resulted in 59% survival of embryos. Previous techniques relying on a mechanical manipulator resulted in 8% survival. Pink bollworm (PBW) embryo injection technology is based in part on methods developed for injection and genetic tr...
متن کاملInactivated mariner-like elements (MLE) in pink bollworm, Pectinophora gossypiella.
We isolated multiple copies of mariner-like element (MLE) from the pink bollworm (PBW), Pectinophora gossypiella, a key lepidopteran cotton pest. Although all the MLE sequences contain multiple mutations accumulated in their transposase coding region, the consensus sequence revealed a putative ancestral transposase encoding 339 amino acid residues with a D,D(34)D motif, and 36 bp inverted termi...
متن کاملCircadian systems, VI. Photoperiodic time measurement in Pectinophora gossypiella.
Diapause (100% incidence) occurs in the moth Pectinophora gossypiella when it is exposed to 24-hour light/dark cycles involving 12 hours of red light (600 nm); only 2% occurs when the photoperiod is extended to 14 hours, again with 600-nm light. This wavelength fails to synchronize all the known circadian oscillations of the moth. These observations appear, therefore, to constitute positive evi...
متن کاملControl of resistant pink bollworm (Pectinophora gossypiella) by transgenic cotton that produces Bacillus thuringiensis toxin Cry2Ab.
Crops genetically engineered to produce Bacillus thuringiensis toxins for insect control can reduce use of conventional insecticides, but insect resistance could limit the success of this technology. The first generation of transgenic cotton with B. thuringiensis produces a single toxin, Cry1Ac, that is highly effective against susceptible larvae of pink bollworm (Pectinophora gossypiella), a m...
متن کاملNew species of Gelechiidae (Lepidoptera) from Ukraine.
Chrysoesthia halimionella, sp. n., Megacraspedus uzunsyrtus, sp. n., Aristotelia confusella, sp. n., and Dirhinosia interposita, sp. n., are described from Ukraine. Adults and genitalia of the new species are illustrated and compared with related species.
