Efficacy of Some Botanicals against Potato tuber moth, <i>Phthorimaea operculella</i> (Zeller, 1873)

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...

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...

Occurrence of Parthenogenesis in Potato Tuber Moth

Parthenogenesis, a natural form of asexual reproduction produced from unfertilized eggs, occurs in many insects in Hemiptera and Hymenoptera, but very rarely in Lepidoptera. The current study aimed to test the larval density dependent occurrence of parthenogenesis in potato tuber moth, Phthorimaea operculella (Zeller; Lepidoptera: Gelechiidae) under laboratory conditions. More than 10% of femal...

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

Evaluation of potato tuber moth (Lepidoptera: Gelechiidae) resistance in tubers of Bt-cry5 transgenic potato lines.

The potato tuber moth, Phthorimaea operculella (Zeller), in tropical and subtropical countries, is the most destructive pest of potato, Solanum tuberosum L. The larvae attack foliage and tubers in the field and in storage. The purpose of this study was to evaluate the efficacy of a Bt-cry5 transgene to control the potato tuber moth in tuber tissues. Tuber bioassays using stored (11-12 mo old) a...
