Larvae may also feed between kernels rows. The mean numbers of larvae/25ear affected by different growth stages of maize ear and maize crosses.<br /> The average numbers of the predator <em>B. picus </em>was 74.63 individual/100plants in the first season 2004. On the other hand the average numbers of the predator in the second season 2005 was 99.00 indivedual/100 plants.<br /> The highest mean numbers of<em> P. simplex</em> larvae in different maize crosses were during the Physiological maturing stage and the lowest mean numbers during the Dough stage in the two successive seasons 2005 and 2006.<br /> The highest mean numbers of <em>P. simplex</em> larvae were recorded in variety Bioner 3062 (4.03 larvae/ear) which uncovering with husks. On the other hand the variety SC10 was the lowest mean numbers of larvae (1.37 larvae/ear) which Cub husks tightly covering ear tip. The percentage of oil which obtained from Bioner 3062 recorded the highest percentage (6.81%) and attractive the highest mean numbers of larvae (4.03 larvae/25ears). On the other hand variety SC10 recorded the lowest percentage of oil (4.07%) and attractive the lowest mean numbers of larvae (1.37 larvae/25ear). https://jppp.journals.ekb.eg/article_221219_31a68a19e5798fbc033599767b87f7fd.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-3677321220071201HYMENOPTEROUS PARASITOIDS ATTACKING THE SUGAR CANE STEM BORER LARVAE, IN MAIZE FIALD AT KAFR El-SHEIKH REGION.105931059922122410.21608/jppp.2007.221224ENS.

Sakha Agriculture Research stationJournal Article20071125A survey of the hymenopterus parasitoids, associated with, the larvae of sugar cane corn borer,<em> Sesamia cretica</em> Led., in Sakha Agriculatural Research Station Farm at Kafr El-Sheikh Governorate during the two successive seasons 2004 and 2005. Four parasitoids species belonging to the Order and Family (Hymenoptera: Braconidae), were recorded. These parasitoids namely: <em>Meterous sp < /em>,<em> Apanteles sp, Cotesia sp < /em> and<em> Gleptoapantelas africanus </em>Haliday., as internal lavrval parasitoids of <em>S. cretica</em>.
The highest percentages of parasitism by<em> Meterous sp < /em>,was recorded on the first week of July (23.6%) during 2004 season, while in the second season 2005 was recorded in the third week of July (24.8%) with an average percentage of parasitism 11.54 and 14.37% during the two successive seasons, respectively.
The highest percentages of parasitism by<em> Apanteles sp,</em> was recorded on the second week of August (33.3%) in the first season and the first week of July (28.8%) in the second season. On the other hand the average percentage of parasitism was 13.79 and 19.16% during the two seasons 2004 and 2005, res<em>p < /em>ectively.
The highest percentages of parasitism by <em>Cotesia sp. </em>was recorded in the first week of August which reached 30.0 and 31.1% in season 2004 and 2005, res<em>p < /em>ectively. While the average percentage of parasitism were 19.13 and 13.9% in the two seasons, respectively.
Regarding to the parasitoid, <em>G. africanus </em>which considers as first record in Egypt as larvae parasitoid on <em>S. cretica,</em> The highest percentages of parasitism were recorded in the second and third week on July (17.7 and 18.0%) during 2004 and 2005 seasons, respectively. On the other hand, the average percentages of parasitism were 4.31 and 4.69% respectively. https://jppp.journals.ekb.eg/article_221224_1294c4ef9fbab1abb9f8f02a2bfe43ce.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-3677321220071201EFFICIENCY OF ENTOMOPATHOGENIC NEMATODES, HTERORHABDITIDAE AND STEINERNEMATIDAE ON THE SNAIL Theba pisana( Muller) IN RAPHAH, NORTH SINAI, EGYPT106011060522123010.21608/jppp.2007.221230ENEman El- Mahdi,Biological Control Research Department, Plant Protection Research Institute (PPRI) ARC, Egypt.F.

The infected snails were observed for 8 days. At the highest inoculums level, <em>H. indicus ,H.bacteriophora riobravis</em> (Hb),<em>H</em>.<em>bacteriophora</em> (HP88)gave mortality percentages up to 100% after 4 days of infection, while the species <em>S . riobravae</em> (Sr)gave 65% mortality at the same inoculum levels and after the same time. No development of the nematodes occurred inside the cadavers of snails. In addition, all cadavers were decomposed completely. In the semi field test, two species ,<em>H. indicus </em>and <em>S. glaseri </em>were sprayed on colonies of snails <em>Theba pisana</em> on the tree branches at three inoculum levels (1000,2000,3000 IJs/ml)with direct spraying. No mortalities were obtained at the two lower concentrations of both species. At the highest level (3000IJs/ml), <em>H. indicus</em>(Hi) gave 57.89% mortality after 3days of application only in the small individuals which ranged between 2-7mm. in length, while <em>S. glaseri</em>(Sg) gave 77.27% after the same time, and same inoculum level. https://jppp.journals.ekb.eg/article_221230_083876e23f1a8975fbd3ab952e11e1a2.pdf
