Twenty-two cowpea genotypes, comprising eighteen elite lines from the CSIR-Savanna Agricultural Research Institute, and three improved cultivars from the International Institute of Tropical Agriculture were evaluated for their susceptibility to infestation and damage by the storage beetle, Callosobruchus maculatus F. The assessment of their relative susceptibilities was based on oviposition, me...
به منظور دستیابی به ترکیبات کم خطر برای مهار آفات انباری اثر سمیت تنفسی، تخم کشی، لاروکشی، بازدارندگی تخمریزی، دورکنندگی و سینرژیستی پنج ترکیـب ترپنــوئیدی شامـل کارواکرول، میرتــول، منتــول، کامفــن و آلـفا- پینن روی سه گونه آفت callosobruchus maculatus (f.)، tribolium confusum و t. castaneum مورد بررسی قرار گرفت. این آزمایشات در قالب طرح کاملاً تصادفی در دمای 2±27 درجه سلسیوس، رطوبت نسبی 5±65 ...
This study compared the behavioral avoidance responses of 4 mosquito malaria vectors, Anopheles minimus, Anopheles dirus, Anopheles maculatus form B, and Anopheles swadiwongporni, to deltamethrin, the primary insecticide used for indoor residual spraying for malaria vector control in Thailand. Six test populations. representing 4 laboratory colonies and 2 wild-caught populations, were observed ...
Larval dispersal is the key process by which populations of most marine fishes and invertebrates are connected and replenished. Advances in larval tagging and genetics have enhanced our capacity to track larval dispersal, assess scales of population connectivity, and quantify larval exchange among no-take marine reserves and fished areas. Recent studies have found that reserves can be a signifi...
The objective of this study was to assess insecticide resistance in anopheline mosquito populations in agroecosystems with high and low insecticide use in a malaria endemic area in Chiang Mai province in northern Thailand. Anopheline mosquitoes were collected in May and June 2004 from two locations with different agricultural insecticide intensity (HIGH and LOW), but similar in vector control s...
چکیده آگامای سر وزغی دم سیاه (Phrynocephalus maculatus maculatus) از مارمولکهای کمیاب روز فعال خانواده آگامیده است که در نواحی بیابانی و دشتهای ماسهای مرکز و جنوب شرقی ایران انتشار یافته است. این تحقیق به منظور بررسی دیمورفیسم جنسی در این گونه از فروردین تا مرداد 1392 انجام شد. در مجموع، 30 نمونه بالغ شامل 15 نر و 15 ماده از چهار ایستگاه حسن آباد، صالح آباد، علیان و یزدان آباد در مناطق جنو...
It has been demonstrated that variant vicilins are the main resistance factor of cowpea seeds (Vigna unguiculata) against attack by the cowpea beetle Callosobruchus maculatus. There is evidence that the toxic properties of these storage proteins may be related to their interaction with glycoproteins and other microvillar membrane constituents along the digestive tract of the larvae. New finding...
The first findings of Limacus flavus in the Lviv region, Western Ukraine, are described. One specimen was shown with an atypical body colouration, without yellow mucus covering it, a monochromatic back and almost complete absence reticulate pattern on mantle, assigned to genus only after dissection. An analysis our own literature data, as well observations from two citizen science databases, sh...
