Characterization of a newly established potato tuber moth (Phthorimaea operculella Zeller) cell line.
BACKGROUND & OBJECTIVE Potato tuber moth (PTM), Phthorimaea operculella Zeller is a widely distributed, devastating pest of potatoes attacking the foliage and infest the tubers in both field and store causing serious economic damage. As application of PTM granulovirus (PTM-GV) has shown significant reduction in damage, attempts were made to develop a new cell line from this insect to grow PTM-G...
متن کاملPopulation biology of the potato tuber moth, Phthorimaea operculella (Lepidoptera: Gelechiidae), in two potato cropping systems in Israel.
The life cycle, within-field distribution, crop damage and impact of natural enemies of the potato tuber moth, Phthorimaea operculella (Zeller) were investigated in two potato cropping systems. The two systems differed in soil type (sandy vs. loess) which in turn affected the choice of cultivars, irrigation programme, insecticide application method (ground vs. aerial), and planting and harvest ...
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 ...
متن کاملlethal and sublethal effects of abamectin and deltamethrin on potato tuber moth, phthorimaea operculella (lepidoptera: gelechiidae)
the potato tuber moth (ptm), phthorimaea operculella (zeller) is one of the important pests of potato in tropical regions. in this research, the toxicity of two insecticides, abamectin and deltamethrin on p. operculella was studied at 26 ± 1 c°, 65 ± 5% rh and photoperiod of 16:8 h (l: d). the concentrations were determined by preliminary dose setting experiments. distilled water was used as co...
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...
