Oviposition behaviour of Gryon gallardoi (Hym.; Scelionidae) on eggs of Spartocera dentiventris (Hem.; Coreidae).
The oviposition behaviour of Gryon gallardoi (Hymenoptera; Scelionidae) on Spartocera dentiventris (Hemiptera; Coreidae) host eggs was investigated in the laboratory. Masses of 12 non-parasitized freshly laid (less than 24 h old) eggs were exposed to 2-5 days old mated females with previous oviposition experience (n = 10). Behaviour was observed for 2 h under the stereomicroscope. The eggs were...

واکنش تابعی شکارگر، به‌عنوان اساس و پایه‌ی دینامیسم شکار- شکارگر در نظر گرفته می‌شود. واکنش تابعی کفشدوزک Serangium montazerii Fürsch در تراکم‌های مختلف (50، 100، 150، 200 و 250) تخم سفیدبالک مرکبات، Dialeurodes citri (Ashmead)، در یک آزمایش open-patch مطالعه شد. این آزمایش در یک اتاقک رشد (دمای °C1 ± 25، رطوبت %5 ± 65 و دوره‌ی نوری 8 :16 ساعت تاریکی: روشنایی) با برگ‌های انتهایی سرشاخه‌ی پرتق...
متن کاملInternal reproductive organs of Cosmoclopius nigroannulatus (Hemiptera: Reduviidae).
The internal reproductive organs of Cosmoclopius nigroannulatus males and females are described, illustrated and measured. No significant difference was registered among immature and reproductive structures of males and their aspect was also similar. However, in females noteworthy differences both in size and aspect were found.

the functional response of a predator is the base of prey-predator dynamics. functional response of serangium montazerii fã¼rsch at different egg densities (50, 100, 150, 200 and 250) of dialeurodes citri (ashmead) was studied in an open-patch experiment, in a growth chamber (25 â± 1â°c, 65 â± 5% rh and a photoperiod of 16: 8 l: d h) on âthompsonâ navel orange (citrus sinensis cv. thompson)...
متن کاملPopulation dynamics of Cosmoclopius nigroannulatus Stal (Hemiptera, Reduviidae) in tobacco culture.
The role of predators influencing populations of insects considered as pests is extremely important for agroecosystems. The population ecology of Cosmoclopius nigroannulatus, a predatory reduvid associated with the tobacco culture was investigated aiming to study the population dynamics of adults, along the culture cycle. In an experimental plot of approximately 300 m2, in Porto Alegre (30 degr...
