The egg parasitoid, Trichogramma brassicae Bezdenko (Hymenoptera: Trichogrammatidae) is the most important and widely distributed species of Trichogramma in Iran. It attacks eggs of several lepidopterous pests, and is a major biological control agent. Rearing parasitoids is necessary for experimental work, and, potentially, for mass release in the field. Selecting a suitable host is critical fo...
A nested polymerase chain reaction protocol yielded positive detection of the maternally inherited cytoplasmic proteobacterium Wolbachia in total genomic DNA from coffee berry borers collected in Benin, Brazil, Colombia, Ecuador, El Salvador, Honduras, India, Kenya, Mexico, Nicaragua, and Uganda. Wolbachia was not detected in specimens from Cameroon, the Dominican Republic, Indonesia, Jamaica, ...
This paper describes a new adaptation of a cognitive vision system in biology field. Our goal is to monitor Trichogramma activities from image sequence. More precisely we aim at recognizing several scenarios of the parasitoid behavior when it parasites the eggs of the Mediterranean flour moth Ephestia kuehniella Zeller (crops-harmful butterfly). The main advantage of our current work is the use...
ارامترهای مختلف زیستی زنبور پارازیتوئید habrobracon hebetor say (hym.: braconidae)، از جمله طول مراحل مختلف سنی، جدول زندگی، پارامترهای تولیدمثلی، پارامترهای رشد جمعیت و نیاز های گرمایی در شرایط آزمایشگاهی روی لاروهای سن 5 پروانه بید آرد ephestia kuehniella zell. در دمای 28 درجه سانتی گراد با رطوبت نسبی 5±60 درصد و دوره نوری 16 ساعت روشنایی و 8 ساعت تاریکی برای سه منطقه چگنی (دو نوع زنبور قهوه ...
The endosymbiotic bacterium Wolbachia pipientis manipulates host reproduction by rendering infected males reproductively incompatible with uninfected females (cytoplasmic incompatibility; CI). CI is believed to occur as a result of Wolbachia-induced modifications to sperm during maturation, which prevent infected sperm from initiating successful zygote development when fertilizing uninfected fe...
chrysoperla carnea is a voracious predator. it is currently mass-reared and released for biological control programs. this study was aimed at finding out the effect of different diets on biological characteristics of adult predator, and to introduce a better and cheaper artificial diet for its mass-rearing. in order to obtain a pure and physiologically homogenous population, the predator was re...
bacillus thuringiensis strains were isolated from various soil samples collected from different regions of kahramanmaraş in turkey and were characterized by their colony morphology, pcr method with cryiab/ac, cryid, cry2 and cyt2 primers, and sds-page of crystal proteins with 130-140 and 60-70 kda molecular weights. plasmid profiles of selected isolates were also analyzed. among the cry genes s...
the green lacewing, chrysoperla carnea (stephens) is one of the important predators of many pests including helicoverpa armigera (hübner) and tetranychus urticae koch. in insectaries, the larvae of this predator are mainly reared on anagasta kuehniella egg. in this research, biological and life table parameters of c. carnea in feeding on a. kuehniella egg as a laboratory prey and two natural pr...
بید آرد،Ephestia kuehniella Zeller ، به عنوان یکی از رایجترین میزبانهای مورد استفاده در پرورش انبوه زنبور پارازیتویید (Habrobracon hebetor (Say) Hym.: Braconidae) و (Trichogramma brassicae Bezdenko (Hym.: Trichogrammatidae) مورد توجه قرار دارد. در این تحقیق، هشت رژیم غذایی متفاوت و با ترکیباتی جدید در شرایط آزمایشگاهی (دمای 1±25 درجه سلسیوس و رطوبت نسبی 5±60 درصد، دوره نوری 14:10 ساعت (روشنای...
