This paper describes a new adaptation of a cognitive vision system in biology field. Our goal is to monitor Trichogramma activities from image sequence. More precisely we aim at recognizing several scenarios of the parasitoid behavior when it parasites the eggs of the Mediterranean flour moth Ephestia kuehniella Zeller (crops-harmful butterfly). The main advantage of our current work is the use...

Trichogramma parasitoids are the most widely used biocontrol agents and play a crucial role in biological control of agricultural forest pests. Many studies have shown that feeding on carbohydrate rich diet can effectively improve their egg laying capacity longevity. However, few reported impact carbohydrate-rich parameters different species parasitoids. In this study, we compared differences b...

Trichogramma are facultative gregarious egg parasitoids that attack a wide range of lepidopterous eggs. Because hosts in which parasitoids develop vary in terms of available food, the progeny produced by parasitoid females vary in size and fitness. While one might expect that the developmental rate and emergence rhythm should be similar for all individuals reared under the same environmental co...

the family of pteromalidae (hym: chalcidoidea) is one of the largest families of parasitic wasp. members of this family wasp comprise of important natural enemies of many harmful insects in major insect orders such as coleoptera, diptera, lepidoptera, hymenoptera and homoptera; therefore they have an important role in biological control of agricultural pests. the chalcid wasps belonging to this...

Trichogramma species (Hymenoptera: Trichogrammatidae) are haplo-diploid egg parasitoids that are frequently used as biological control agents against lepidopteran pests. These wasps display two reproductive modes, including arrhenotoky (bisexuality) and thelytoky (unisexuality). Thelytokous forms are often associated with the presence of endosymbiotic Wolbachia bacteria. The use of thelytokous ...
