The daily survival rate was investigated ofTrichogramma platneri Nag. wasps supplied with flowers (both with and without anthers) of avocado cv. Ettinger and cv. Fuerte, anthers of avocado flowers, or flowers ofOxalis cernua, Mercurialis annua andEuphorbia sp. The life span of wasps supplied with anthers or weed flowers was less than 24 hours, whereas it was longer on avocado. However, none of the avocado varieties appeared outstanding in sustaining the wasps. It follows that nectar is the wasp… 
Selective flowers to attract and enhance Telenomus laeviceps (Hymenoptera: Scelionidae): a released biocontrol agent of Mamestra brassicae (Lepidoptera: Noctuidae).
The potential of selected flowers to attract and promote T. laeviceps under laboratory conditions was investigated and it was found that flowers of F. esculentum and C. cyanus were attractive in contrast to V. sativa, and survival was similar on all treatments.
Effects of artificial diets and floral nectar on longevity and progeny production of Trichogramma euproctidis Girault (Hymenoptera: Trichogrammatidae) Bitki nektari ve yapay besinlerin Trichogramma euproctidis Girault (Hymenoptera: Trichogrammatidae)'in ömür uzunluğu ve döl verimi üzerine etkisi
Although floral nectar qualities may be of greater importance to parasitoid longevity when selecting floral resources for conservation biological control, the artificial diets proved to be suitable foods for sustaining the development and reproduction of T. euproctidis.
Inter- and intraspecific variation of nutritional and environmental adaptation of egg-parasitoids of the genus Trichogramma (Hymenoptera, Trichogrammatidae)
The results indicate that Trichogramma adults are feeding upon pollen, and nutritional quality of pollen differs between plant species, and honeybee-pollen may be used to improve massrearing of Trichogramsma species.
Adult feeding and mating effects on the biological potential and parasitism of Trichogramma pretiosum and T. acacioi (Hym.: Trichogrammatidae)
Mated and fed female parasitoids should be released in crop systems to increase the biological control of Trichogramma species.
Genetically Modified Crops and Biological Control with Egg Parasitoids
A fuller understanding of any effects of GM crops on egg parasitoids is particularly significant in the context of analyses pointing to the importance of movement of natural enemy populations among crops and between seasons within a landscape, for pest management and biological control at regional scales.
Effect of honeybee products, as food supplements, on the biological activities of three Trichogramma species (Hymenoptera: Trichogrammatidae)
Providing a suitable diet may help to enhance the biological activities for the rearing parasitoids, and all diets containing honey improved longevity and fecundity.
Effects of transgenic Bt maize pollen on longevity and fecundity of Trichogramma ostriniae in laboratory conditions
No significant differences in longevity, number of parasitised eggs, offspring emerged and the offspring sex ratio were observed between the females feeding on pollen of Bt maize and non-Bt maize, this was shown in experiments with suspension of 10% honey and with water.


Parasitization of Amorbia cuneana (Lepidoptera: Tortricidae) and Sabulodes aegrotata (Lepidoptera: Geometridae) on Avocado in Southern California
Immature stages of Sabulodes aegrotata and Amorbia cuneana Walsingham were collected from avocado foliage during 1978 through 1980 and held for parasite emergence, with seven being parasitic on both pests.
Biological Control of Two Avocado Pests Amorbia cuneana and omnivorous looper on avocado can be controlled by parasite
Two apparently native insects are the most common lepidopterous pests on avocado in southern California: Amorbia cuneana Walsingham and the omnivorous looper, Sabulodes aegrotata (Guenee). Both are
The Effects of Flowers on the Longevity and Fecundity of Two Native Parasites of the European Pine Shoot Moth in Ontario
The effects of feeding on various flowers on the longevity of Exeristes comstockii Cresson and the longevity and fecundity of Hyssopus thymus Girault and the establishment and encouragement of flowering plants in plantations are recommended.
Beneficial effects of weeds in pest management — a review
Examples are given of weeds which serve as food sources for alternative hosts of insect predators and parasites or for the parasites themselves, and the implications for weed and insect control and for crop production are discussed.
