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...
متن کاملCompetitive Interactions between Parasitoids Provide New Insight into Host Suppression
Understanding the dynamics of potential inter- and intraspecific competition in parasitoid communities is crucial in the screening of efficient parasitoid species and for utilization of the best parasitoid species combinations. In this respect, the host-parasitoid systems, Bemisia tabaci and two parasitoids, Eretmocerus hayati (exotic) and Encarsia sophia (existing) were studied under laborator...
متن کاملEffects of Conunonly Used Insecticides on the Potato Tuherworm and Its Associated Parasites and Predators in Potatoes
J. Econ. Enlomol. 74: 30}-308 (1981) Larvae and adults of Phthorimaea operculella (Zeller) in potato foliage were effectively controlled by commercial applications of azinphosmethyl and a combination of methomyl and methamidophos, but eggs and pupae were not significantly affected. Azinphosmethyl, methomyl, and methamidophos provided adequate control of foliar larval populations, but larval par...
متن کاملSegregation and efficacy of the cry1Ia1 gene for control of potato tuberworm in four populations of cultivated potato.
The potato (Solanum tuberosum L.) cultivar 'SpuntaG2' contains a single copy of the Bacillus thuringiensis (Bt) cry1Ia1 gene and controls potato tuberworm (Phthorimaea operculella Zeller, Lepidoptera: Gelechiidae). Two potato cultivars and two breeding lines were crossed with SpuntaG2 creating four populations used to study cry1Ia1 segregation and efficacy. The cry1Ia1 gene segregated in each o...
متن کاملDetection of Multiple Potato Viruses in the Field Suggests Synergistic Interactions among Potato Viruses in Pakistan
Viral diseases have been a major limiting factor threating sustainable potato (Solanum tuberosum L.) production in Pakistan. Surveys were conducted to serologically quantify the incidence of RNA viruses infecting potato; Potato virus X (PVX), Potato virus Y (PVY), Potato virus S (PVS), Potato virus A (PVA), Potato virus M (PVM) and Potato leaf roll virus (PLRV) in two major potato cultivars (De...
