Population 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 کاملCharacterization 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 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...

abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
