Artificial diets for rearing the Colorado potato beetle, Leptinotarsa decemlineata
Colorado potato beetles have been reared successfully through 12 generations on artificial diets containing either 2.5% potato leaf powder or 2.5% lettuce leaf powder/0.75% potato leaf powder. For all but one of the treatment groups, the mean duration of each of the four larval stages was between 0.8 and 1.5 days longer than the durations exhibited by control beetles that had been fed on potato...
متن کاملAn entomopathogenic bacterium, Pseudomonas putida, from Leptinotarsa decemlineata
Th e Colorado Potato Beetle (CPB), Leptinotarsa decemlineata (Say) (Col.: Chrysomelidae), is a pre-eminent pest on solanaceous crops worldwide, and much research has focused on the diff erent components of its variable population dynamics. L. decemlineata has developed resistance to insecticides used for its control. Consequently, alternative methods are needed urgently for the control of this ...
متن کاملModeling Colonization of Overwintered Immigrant Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)
Colonization of potato (Solanum tuberosum [L.]) Þelds by Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), has often been recognized as a process that initially results in an edge-biased spatial pattern. We modeled this spatial process by measuring distance of immigration for individual overwintered adults.Distancewasmeasured to the nearest Þeld edge or to the...
متن کاملHormonal Control of Reversible Degeneration of Flight Muscle in the Colorado Potato Beetle, Leptinotarsa Decemlineata Say (coleoptera)
In the hibernating (diapausing) Colorado potato beetle, Leptinotarsa decemlineata Say, the flight muscles show pronounced degeneration. The muscle fibrils are greatly reduced in diameter and the sarcosomes are virtually absent. Similar signs of degeneration could be produced by extirpation of the postcerebral complex of endocrine glands, the corpora cardiaca and corpora allata. Reimplantation o...
متن کاملMorphology and ultrastructure of chemosensory sensilla of labio-maxillary complex in the Colorado potato beetle, Leptinotarsa decemlineata (Col.: Chrysomelidae), larvae
سوسک برگ‌خوار سیب‌زمینی، Leptinotarsa decemlineata (Say)، یکی از مهمترین آفات سیب‌زمینی و دیگر محصولات خانواده‌ی Solanaceae می‌باشد. نوع، تعداد و پراکندگی گیرنده‌های حسی روی پالپ‌های آرواره‌ای و لبی لارو سوسک برگ‌خوار سیب‌زمینی توسط میکروسکوپ الکترونی مطالعه شد. در مجموع تعداد 32 گیرنده‌ی حسی شامل سه نوع بازیکونیکا (basiconica)، تریکوئید (trichoid) و دیجیتیفرم (digitiform) روی پالپ‌های آرواره‌ی...
