The Integration Between Trichogramma Evanescens West. (Hymenoptera: Trichogrammatidae) and Selected Bioinsecticides for Controlling the Potato Tuber Moth Phthorimaea Operculella (Zell.) (Lepidoptera: Gelechiidae) of Stored Potatoes

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

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...

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...

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...
