“…Fagopyrum esculentum has good agronomic performance as it germinates easily, has a short sowing-Xowering time, its seed is inexpensive and readily available. These agronomic characteristics combined with the beneWcial eVects F. esculentum has for parasitoids makes it a good candidate understorey plant for use in integrated pest management programs (Bowie et al, 1995) and our results suggest it may be the most beneWcial plant for use with Gonatocerus spp. parasitoids.…”

The eVect of dietary supplements on the longevity of male and female Gonatocerus ashmeadi, G. triguttatus and G. fasciatus (Hymenoptera: Mymaridae), was determined in the laboratory. Treatments included: water only, 3:1 honey-water solution, Xoral and extraXoral nectars from Wve diVerent plants (excised stems from Fagopyrum esculentum, Lobularia maritima, Phacelia tanacetifolia, Anethum graveolens and Vicia faba), honeydew from Coccus hesperidum and Homalodisca vitripennis (formally H. coagulata), a commercially available food supplement (Eliminade) and citrus foliage. Additionally, the sugar composition of each food resource was determined using HPLC and whole Xower extracts. Honey-water and F. esculentum nectar signiWcantly increased longevity of male and female G. ashmeadi, G. triguttatus, and G. fasciatus up to 1860%, 1323% and 1459%, respectively, when compared with water. For both sexes and all three parasitoid species, survival on citrus foliage, H. vitripennis excrement, and P. tanacetifolia Xowers was equivalent to that on water only. The longevity of G. ashmeadi and G. triguttatus was up to 539% higher on Eliminade compared with water only, however there was no signiWcant eVect of Eliminade on survival of G. fasciatus. Coccus hesperidum honeydew increased survival times up to 665% for all mymarid species compared with citrus foliage alone. HPLC analysis indicated that food resources most beneWcial to Gonatocerus parasitoids possessed a high proportion of glucose (up to 44%) and fructose (up to 53%), suggesting that sucrose may not be as important for parasitoid survival. Citrus and P. tanacetifolia Xowers contained favorable proportions of glucose and fructose, but the inability of Gonatocerus spp. to beneWt from this may be related to Xower morphology which could prevent access to nectar.

“…The diversitydriven reduction of herbivore damage has typically been attributed either to an increase in predator and parasite abundance (the "enemies" hypothesis), or to the fact that the crop host is less concentrated in a diverse setting, reducing the likelihood that an herbivore will be able to locate and colonize the non-contiguous crop (the "resource concentration" hypothesis) (Root 1973). Buckwheat, Fagopyrum esculentum Moench (Polygonaceae), a common cover crop, has been reported as an excellent source of nectar and habitat for natural enemies, with the added benefit of a short sowing-to-flower time (Bowie et al 1995). Beneficial hymenopteran species, in particular, benefit from the increased nectar resources available in buckwheat (Ponti et al 2007;Taki et al 2009).…”

“…F. esculentum is an annual that germinates easily, has a short sowing-Xowering time. Seed of F. esculentum is also inexpensive and readily available (Bowie et al, 1995). F. esculentum may be more beneWcial for G. ashmeadi since nectar enhances survival of both sexes of G. ashmeadi (Irvin et al, 2006a).…”
