“…In our study, we found few insects which are important pests (stink bugs, leafrollers, grasshoppers, etc.) of blueberry in different countries like in USA, Canada, Australia, Argentina and China (Adamczyk et al, 2012;Drummond and Groden, 2000;Macdonald, 1997;McGregor et al, 1998;Rocca and Greco, 2011). According to different studies, stink bugs feed on the fruit of a wide range of plants including blueberries (Adamczyk et al, 2012;Coneva, 2010).…”

“…According to different studies, stink bugs feed on the fruit of a wide range of plants including blueberries (Adamczyk et al, 2012;Coneva, 2010). Leafrollers (Tortricidae) are a greater problem as a contaminant of harvested blueberries than as direct damagers of leaves, buds, shoots and fruit (Macdonald, 1997;McGregor et al, 1998). In the blueberry plantations larvae (Grapholita packardi) feed inside the shoots or fruit (Chapman and Lienk, 1971).…”

“…In order to determine the efficiency of the endemic egg parasitoid Trichogramma, we compared it with the commercial strain of T. turkestanica SQG that has been obtained from Natural Enemies Mass Production Center, Faculty of Agriculture, Cairo University, Egypt. Artificial egg mass of E. kuehniella was prepared by gluing 100 to 200 eggs to a small piece of cardboard and introduced to one female and one male wasp in a Petri dish (5 cm in diameter) that contained a streak of dilute honey as a food source (McGregor et al, 1998). The cardboards were daily changed until the death of parasitoid females.…”

Parasitoids of Trichogramma (Hymenoptera: Trichogrammatidae) parasitize the eggs of many species of Lepidoptera and have been used for the biological control of numerous pest species. We collected this parasitoid from Taif governorate, KSA in summer of 2009. It is difficult to differentiate between Trichogramma species because of their small size and lack of differences in morphological characters. Therefore, different molecular markers were employed to characterize this species, including direct amplification of the internal transcribed spacer 2 (ITS2) of ribosomal DNA and by restriction fragment length polymorphism followed by sequencing. The results show that ITS2 region is 491 bp and indicated that this is a new stain of Trichogramma. We named this strain TaifKSA. From the tested restriction enzymes, only EcoRI and PstI cut the PCR product of ITS2 region. We compared the biological characteristics of the strain under investigation with other commercial strain (SQG) of the same species and no significant differences between them have been shown.

“…This study has important implications for Trichogramma inundation programs. Also, for selecting Trichogramma species and strains (Hassan, 1989;McGregor et al, 1998;Tabone et al, 1999), attention should be paid to matching the behavioral and reproductive characteristics of Trichogramma species to the ovipositional strategies (single eggs versus egg masses) of target pests.…”

The oviposition behavior of T. evanescens in each patch type (1mm 2 ) with 12 single spaced or clustered eggs of Anagasta kuehniella Zeller was observed continuously, recorded and calculated the patterns of patch use, time budgets, and the sequence of sex allocation for up to 1 hr. or until the female left the patch. The only significant behavioral event is the total walking in cluster patch because the female takes significantly more time walking out of patch. The parasitoid spends much time resting on eggs of cluster patch than in single patch. No significant differences occurred between single and cluster patches in their influence on the residence time spent in a patch. The handling time in a patch showed significant differences between single and cluster patch. There is no giving up time in single patch but it happened in cluster patch. Clustered patches led to a reduction in percent drumming and grooming time, but an increase in percent resting and total walking time. There were no significant differences between single and cluster patches in the number of eggs encountered. The progeny sex ratio from the parasitized eggs showed very little variation and was insignificant between patch types. The percent male progeny was 16.1 and 21.2 % in single and cluster patches, respectively. There were no significant differences for oviposition time for both male or female eggs in single and cluster patches. The female tended to produce male eggs at the second oviposition event in single patch which represented 16.67 % of the total male eggs deposited, while it deposited male eggs (8.7 %) at the first oviposition event. This study has important implications for Trichogramma inundation programs and selecting Trichogramma species and strains, it should be taken into consideration to match the behavioral and reproductive characteristics of Trichogramma species to the ovipositional strategies (single eggs versus egg masses) of target pests.
