Bu çalışmada Leptinotarsa decemlineata (Say.) (Coleoptera: Chrysomelidae)’nın beslenme miktarına sıcaklığın etkisi araştırılmıştır. Sıcaklığın zararlının miktarı üzerine etkisi, Logan-10 modeli kullanılarak açıklanmıştır. amaçla, patates bitkisinden alınan yapraklı dal parçası, 24 saatlik beslenmesinden önce ve sonra tartılarak eksilen ağırlık belirlenmiştir. Aynı koşullarda parçasının saat içe...

Rotated and non-rotated commercial potato fields were sampled intensively to follow Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), colonization and subsequent oviposition patterns in the spring of 1990 and 1991. Maximum densities of colonizing adults ranged from 0 to 14,891/ha and maximum egg mass densities ranged from 0 to 48,451/ha. Crop rotation generall...

The Colorado potato beetle (Leptinotarsa decemlineata (Say)) is a significant pest of potato plants that has been controlled for more than two decades by neonicotinoid imidacloprid. L. decemlineata can develop resistance to this agent even though the molecular mechanisms underlying this resistance are not well characterized. MicroRNAs (miRNAs) are short ribonucleic acids that have been linked t...

Heterochromatin characteristics have been studied in Leptinotarsa decemlineata belonging to the leaf beetles (Chrysomelidae) and compared to the thoroughly analysed heterochromatin of the mealworm beetle Tenebrio molitor, representing darkling beetles (Tenebrionidae). C-banding reveals heterochromatin in pericentromeric regions of all chromosomes of both species; however heterochromatic blocks ...
