functional response of trichogramma embryophagum( hym.: trichogrammatidae) on two laboratory hosts

ردیابی و شناسایی باکتریWolbachia در زنبور( Trichogramma brassicae (Hym.: Trichogrammatidae

باکتری‏های‏ (α-proteobacteria) Wolbachia هم‌زیست‏های درون سلولی هستند که در بافت‏های تناسلی تعدادی از بندپایان یافت می‏شوند. القاء بکرماده‏زایی در زنبورهای تریکوگراما اغلب توسط این باکتری که از طریق سیتوپلاسم تخم منتقل می‏شود، صورت می‏گیرد. در این تحقیق، آلودگی به باکتری Wolbachia در 5/49، 6/3 و 5/2 درصد از افراد جمعیت‏های طبیعی زنبور Trichogramma brassicae Bezdenko که به‌ترتیب از بابلسر، چمستا...

گزارش زنبور ( Trichogramma ingricum (Hym.: Trichogrammatidae از ایران

functional response of trichogramma brassicae bez. (hym.;trichogrammatidae) to different egg densities of anagasta kuehniella zell. and plodia interpunctella hub.

functional response of trichogramma brassicae bez. to different densities of eggs of two host species anagasta kuehniella zell. and plodia interpunctella hub. was studied under laboratory conditions (24±1°c, 65±10% rh and 16: 8 l:d photoperiodism). one day old eggs of either host were offered to individual females of t.brassicae in densities 2, 4, 8, 16, 32, 64 and 128 respectively in 21, 15, 1...

horizontal transmission of wolbachia in trichogramma wasps (hym., trichogrammatidae)

wolbachia is an intracellular endosymbiont, which can induce thelytokous parthenogenesis in trichogramma egg parasitoids with the infected females producing daughters without any mating. with regard to the usual transfer of wolbachia which is vertical from the mother to her offspring through the cytoplasm of eggs, this manipulation of host’s reproduction can enhance its transmission to future g...

report of trichogramma ingricum (hym.: trichogrammatidae) from iran

trichogramma ingricum sorokina, 1984, an egg parasitoid, only known from russia (st. petersburg), here is newly recorded from northern iranian provinces including west and east azarbaijan and mazandaran. the localities and hosts are as follows: tabriz, on eggs of cydia pomonella (l.); urmia (chubtarash, najafabad-e gharebagh, tasmalu, ghulenji), on eggs of c. pomonella and lobesia botrana den &...

effect of temperature on functional response of carob moth egg parasitoid, trichogramma brassicae bezdenko. (hym.: trichogrammatidae), collected from pomegranate orchards of yazd

ectomyelois ceratoniae zeller (lepidoptera.: pyralidae), is the key pest of pomegranate in iran. trichogramma wasps could be used as effective agents of biological control that can also be used effectively in ipm programs. the effect of host density on parasitism of trichogramma brassicae was studied by exposing densities of 4, 8, 10, 20, 40, 60, 80 and 120 eggs of factitious host (sitotroga ce...
