Constitutive expression of a synthetic cry1Ab gene confers resistance to potato tuber moth (Phthorimaea operculella Zeller) larva

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...

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 ...

Evaluation of genetically modified potatoes against the potato tuber moth, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) under laboratory and non-refrigerated store conditions in South Africa

the efficacy of some medicinal plant extracts and essential oils against potato tuber moth, phthorimaea operculella (zeller) (lepidoptera: gelechiidae)

the potato tuber moth (ptm), phthorimaea operculella zeller (lepidoptera: gelechiidae), is an important pest of potato and other solanaceous plants. it is cosmopolite and oligophage that exists in most countries where potatoes are grown. because of chemical treatment adverse effects, there is a necessity to find safe alternatives to synthetic insecticides. so, medicinal plants are promising sin...

Push-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 ...
