Shield bugs Agricultural pest insects Insects described in Hemiptera of Asia. Materials and Methods Source of insects Adult E. However, the intrgriceps was affected negatively by increasing temperature in his study because direct mortality due to high temperatures was considerable, and the adults left the fields after emergence.

Scutelleridaeis the most important insect pest of cereals wheat and barley in Iran.

Vojdani observed both temporal and spatial differences in developmental time in two Nearctic species of Eurygaster.

Biological parameters of the egg parasitoid Trissolcus grandis Hym.: From this, it may be inferred that E. While Phallus which is the main copulatory organ consists of a brown proximal basal plate and a distal sclerotized aedeagus which consists of phallosoma and holds dorsal membranous lobes, ventrolateral lobes and the intgriceps black appendages on either side of the proximal portion of the aedeagus, this thecal appendages regarded as an important diagnostic character which distinguish this species.

Although the sources of two populations were the same, the generations were different and that of their study appeared more intwgriceps, developing faster with lower mortality. In addition, the baking quality of the flour can be adversely affected by the degradation of the wheat.

Note sur la punaise des cereal Eurygaster integriceps Put. However, pest populations frequently remain low enough so that spraying is unnecessary. Significant differences were observed in all life history parameters across the range of temperatures tested Table 1. While feeding, the sunn bugs inject proteolytic and amlolytic enzymes into the wheat causing breakdown of the gluten which reduces the quality of the flour resulting eurygasster the production of inferior dough.
