Evaluation of Bt-cry1Ia1 (cryV) Transgenic Potatoes on Two Species of Potato Tuber Moth, Phthorimaea operculella and Symmetrischema tangolias (Lepidoptera: Gelechiidae) in Peru
The effect of Bt-cry1Ia1 (cryV now designated cry1Ia1 under revised nomenclature) of potato transgenic plants on the two species of potato tuber moth, Phthorimaea operculella (Zeller) and Symmetrischema tangolias (Gyen), was tested in Peru. Detached leaf bioassays were done using 10 neonate larvae per replication on each transgenic line of bred potato varieties Atlantic and Spunta. Mortality in...
متن کاملOccurrence of Parthenogenesis in Potato Tuber Moth
Parthenogenesis, a natural form of asexual reproduction produced from unfertilized eggs, occurs in many insects in Hemiptera and Hymenoptera, but very rarely in Lepidoptera. The current study aimed to test the larval density dependent occurrence of parthenogenesis in potato tuber moth, Phthorimaea operculella (Zeller; Lepidoptera: Gelechiidae) under laboratory conditions. More than 10% of femal...
متن کاملResistance of potato germplasm to the potato tuberworm (Lepidoptera: Gelechiidae).
The evaluation of potato germplasm for resistance to potato tuberworm, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae), is a valuable component of integrated pest management; however, few attempts have been made to identify natural genetic tuber resistance to tuberworm on potato germplasm. The objective of this study was to screen potato germplasm with potential tuberworm resistance...
متن کاملTomato fruit size, maturity and alpha-tomatine content influence the performance of larvae of potato tuber moth Phthorimaea operculella (Lepidoptera: Gelechiidae).
Various physical and chemical properties of host plants influence insect larval performance and subsequent adult fitness. Tomato plants are relatively new hosts to the potato tuber moth, Phthorimaea operculella (Zeller), with the fruit being its preferred feeding site. However, it is unclear how the biochemical and physical properties of tomato fruits relate to potato tuber moth performance. Si...
متن کاملPush-Pull Effects of Three Plant Secondary Metabolites on Oviposition of the Potato Tuber Moth, Phthorimaea operculella
The push-pull effects of three plant secondary metabolites, azadirachtin, eucalyptol, and heptanal, on the oviposition choices of potato tubers by the potato tuber moth, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) were tested in the laboratory. Azadirachtin at concentrations from 1.5 to 12 mg/L had a significant repellent effect on oviposition. Eucalyptol at concentrations from ...
