Presentation about Sunn Pest and its biology.

IPM of Sunn pest in Arabic.

Effect of density of Sunn pest's egg parasitoids on parasitism rate and grain quality were studied at three levels of infestation of Sunn pest in cages in field. No significant differences of parasitism rate were found when parasitoids density was 1, 2 and 3 parsitoids/m2 at Sunn pest density 2 and 4 insects/m2. Grain quality of all infested treats...

Sunn Pest Eurygaster integriceps Put. (Hemiptera: Scutelleridae) has been recognized as a serious pest of wheat and barley in the Near and Middle East as well as much of the former USSR. In Syria this insect is one of the most important insects of cereals and causes severe damage every year. An average of 155.4 thousand ha are sprayed with insectic...

Summary Wheat is the most important staple food in Syria. Sunn pest Eurygaster integriceps Put. is the most damaging pest of this crop in many countries in West and Central Asia, including Syria.

Four isolates of entomopathogenic fungus Beauveria bassiana (Bals.) Vuil. were tested at concentration 1 X 105 conidia/ml for efficacy on late instar larvae of Pine Processionary Thaumetopoea pityocampa Schiff. under laboratory conditions in entomology laboratory in Scientific Agricultural Research Center in Aleppo. The first dead larvae by the fun...

Four laboratory trials were conducted using seven species of entomopathogenic nematodes (EPN). These included Heterorhabditis indica, H. bacteriophora, H. zealandica, Steinernema riobravae, S. carpocapsae, S. glaseri, and S. feltiae. Adult overwintering Eurygaster integriceps were challenged with three concentrations of infective juveniles (IJ). In...

There has been very little progress towards the use of host plant resistance against Sunn Pest worldwide. Besides the narrow genetic base in cultivated wheat for resistance to this pest, there are great difficulties in screening in hot spots in the field because of aerial insecticide sprays. Also, there was no reliable screening technique under art...

Evaluation of susceptibility of some barley local varieties and experimental lines to infestation with barley stem gall midge Mayetiola hordei Keiffer. Arab, A., S. Khoja, M. Abdel Hay, K. Hukan, Y. Azar, B. Koro and R. Kudsiyeh. 2015. Evaluation of susceptibility of some barley local varieties and experimental lines to infestation with barley ste...

This study was conducted at three agricultural research stations in Aleppo province: Yahmol station (56 km north of Aleppo, rainfall 420 mm), Tel-Hadya station (38 km southwest of Aleppo, rainfall 335 mm), Hmaimah station (55 km east of Aleppo, rainfall180 mm), to evaluate the susceptibility of some barley local varieties and promising experimental...

The virulence of Beauveria bassiana to overwintering Sunn pest adults was determined in the laboratory using micro-application techniques. Five microliter of 2 × 103, 2 × 104, 2 × 105, 2 × 106, 1 × 107, 2 × 107, 1 × 108 conidia/ml-1 were used in November, January and March. Applications were made to the mesosternum of adults. Mortality was recorded...

Surveys of Sunn Pest eggs and egg parasitoids were made in three northern provinces of Syria, Idleb, Aleppo and Al Hassakeh in the 2003 field season. Egg laying occurred from 7 April until 30 May, with parasitized eggs present within the first week of egg observance and continuing throughout the season. Parasitoids were recovered from all provinces...

Percent parasi...

The biology of two species of Sunn pest (Eurygaster integriceps Put.) egg parasitoids Trissolcus grandis Thomson, Trissolcus simoni Mayr (Scelionidae, Hymenoptera), was investigated under laboratory conditions (22+2 ºC, RH 60-70%, l6:8 L: D photoperiod) in 2001. Female longevity was 14.0 and 15.6 days, the mean number of parasitized eggs/ female wa...

Sunn Pest ( Eurygaster integriceps Puton.) is the most important insect pest of wheat in Syria. Hymenopteran egg parasitoids are among the natural enemies that contribute to the reduction of Sunn Pest populations. Our surveys from 1997-1999 revealed six egg parasitoid species: Scelionidae; Trissolcus grandis (Thomson), T. simoni (Mayr), T. vassilie...
