Potato Tuberworm Phthorimaea operculella (Zeller) (Lepidoptera: Gelechioidea) Leaf Infestation Affects Performance of Conspecific Larvae on Harvested Tubers by Inducing Chemical Defenses

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...

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...

Evaluation of a granulovirus (PoGV) and Bacillus thuringiensis subsp. kurstaki for control of the potato tuberworm (Lepidoptera: Gelechiidae) in stored tubers.

Liquid suspensions and dry formulations of a granulovirus (family Baculoviridae, genus Granulovirus, PoGV) derived from infected larvae and the bacterium Bacillus thuringiensis subsp. kurstaki (Berliner) (Btk) were evaluated for control of the potato tuberworm, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae), in stored tubers. Laboratory bioassays at 25 degrees C showed that both Po...

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

biology of potato tuberworm, phthorimaea operculella (lepidoptera: gelechiidae), on the leaves of ten potato cultivars under

the potato tuberworm, phthorimaea operculella (zeller) (lepidoptera: gelechiidae), is one of the most damaging pests of cultivated potato (solanum tuberosum l.) crop, in both field and stores in tropical and subtropical regions. the biological parameters of this pest were evaluated in the growth chamber at 24±1ºc, 65±5% rh and photoperiod of 14:10 h (l:d) on leaves of ten potato cultivars, agri...
