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

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

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...

Adult carbohydrate feeding affects reproduction of Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae).

Reproduction of most insects depend on nutrients accumulated during the larval stage, but many lepidopteran species will also depend on nutrients obtained at the adult stage. Feeding at the adult stage allows the intake of carbohydrate and amino acid rich solutions, which may have an effect on the species reproduction and population growth. The objectives of the current study were to characteri...

Tomato fruit size, maturity and alpha-tomatine content influence the performance of larvae of potato tuber moth Phthorimaea operculella (Lepidoptera: Gelechiidae).

Various physical and chemical properties of host plants influence insect larval performance and subsequent adult fitness. Tomato plants are relatively new hosts to the potato tuber moth, Phthorimaea operculella (Zeller), with the fruit being its preferred feeding site. However, it is unclear how the biochemical and physical properties of tomato fruits relate to potato tuber moth performance. Si...
