Comparative Life Tables of the Potato Tuberworm, Phthorimaea operculella, on Leaves and Tubers of Different Potato Cultivars

The potato tuberworm, Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae), is a serious pest of the potato, Solanum tuberosum L. (Solanales: Solanaceae), in both fields and stores in tropical and subtropical regions. In the present study, the susceptibility of different potato cultivars to P. operculella was evaluated by measuring life table parameters. Tests were undertaken with leaves a...

Resistance of potato germplasm to the potato tuberworm (Lepidoptera: Gelechiidae).

The evaluation of potato germplasm for resistance to potato tuberworm, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae), is a valuable component of integrated pest management; however, few attempts have been made to identify natural genetic tuber resistance to tuberworm on potato germplasm. The objective of this study was to screen potato germplasm with potential tuberworm resistance...

host preference and biology of potato tuberworm, phthorimaea operculella (zeller) (lep.:gelechiidae), on leaves of 12 potato germplasm in greenhouse

the potato tuberworm, phthorimaea operculella (zeller), is a major pest of potato in both store and field. in this research, host preference, biology and life table parameters of this pest were studied on leaves of 12 potato germplasm including seven commercial cultivars (agria, ausonia, sprit, satina, savalan, kondor, morene) and five iranian clones (pi396156-5, pi397045-15, pi397097-2, pi3970...

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 ...

BIOLOGICAL CONTROL Insecticidal Activity of the Granulosis Virus in Combinationwith Neem Products and Talc Powder Against the Potato Tuberworm Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)

مقاومت تعدادی از ارقام تجاری و ژنوتیپ های سیب زمینی نسبت به بید سیب زمینی، phthorimaea operculella (zeller) resistance of some potato cultivars and genotypes to the potato tuberworm, phthorimaea operculella (zeller)

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...
