OVICIDAL EFFICIENCY OF SOME BOTANICAL OILS AGAINST HATCHABILITY OF POTATO TUBER MOTH, PHTHORIMAEA OPERCULELLA EGGS AND THEIR SIDE EFFECT ON CHRYSOPERLA CARNEA UNDER LABORATORY CONDITIONS

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...

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

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...

lethal 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...

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 ...
