Eurygaster integriceps is a species of shield bug in the family Scutelleridaecommonly known as the sunn pest or corn bug. Spermatheca simple and obvious from the dorsal view of the female genitalia as pale brown appendages Figures 11a and 11b. Oviposition lasts 30 to 50 days. Females oviposit in clusters of eggs, mostly on the undersides of smooth leaves. eurygastrr

Male abdomen Dorsal view ; b. The post-diapause adult life of females can be divided into three components, the preoviposition, oviposition, and post-oviposition periods.
These groups are also recognized as migrant and resident bugs, respectively Radjabi Eurygaster integriceps Puton; male genitalia: Researchers at the Entomology Research Laboratory at the University of Vermont and agricultural researchers working throughout the infested region have been co-operating since to produce an integrated management plan for the sunn pest.
In other projects Wikimedia Commons. Scutelleridaeis the most important insect pest of integricwps wheat and barley in Iran. A rurygaster study was carried out in order to determine the effect of temperature on life history parameters of the pest. The number of pests varies enormously from year to year and a significant attack may occur about once in every seven years, potentially causing yield losses worth tens of millions of dollars.
The objective of the current work is to describe the morphology of the midgut of E. The 1st and 2 nd abdominal sternites fused and each sternal sclerite on its lateral side hold two structures, the one single spiracle and just below it a paired structure called trichobothria, and the seventh abdominal segment is more rounded than the other, it is convex ventrally, while the eighth abdominal segment is cup-shaped surround the genital capsule, pale brown colored.
Can damage corn and millet also. A pair of dark brown colored, integgiceps structures connected with the basal plate occurs called paramere or claspers, which are well developed and probably help in copulation Figures 10a – 10d.
Despite a long history of the pest in Iran, there are few studies, if any, on the effects of environmental factors on its demography. Retrieved from ” https: The following life table parameters were measured using the procedures of Carey IGRs prevent the emergence of adults and decreases their intergiceps.
Food was replaced two to three times a week and water was provided continuously in a vial. The adult, which is mm long, is grayish-yellow to black. Articles ehrygaster ‘species’ microformats. Head semi-triangular shaped, wider than long, about 1. Maafi and Parker and Neyshabouri measured demography of the pest in separate studies under constant physical conditions. However, despite the obvious effect of temperature on factors affecting population growth rate, no study has yet quantified its effects on mortality, natality, and developmental rate of the pest.
An entire crop may be destroyed in the absence of control measures. Pygophore Dorsal view ; c.

Mean post-diapause pre-oviposition periods of Eurygaster integriceps females held at four different temperatures. Entomopathogenic nematodes and various isolates of entompathogenic fungi also infect and kill the pests.
