In a cage experiment, parasitism by Anagrus of leafhopper eggs on grapes was greater when adults had access to flowering buckwheat than to buckwheat without flowers.

Other claims from this paper (9)
- Intervention effect Cover crop had no effect on adult Anagrus abundance in 1996.
- Intervention effect In 1997 adult Anagrus were more abundant within edge vines with buckwheat than in vines with clover or sod.
- Observation Adult Anagrus were more abundant at the vineyard edge, especially early in the season.
- Intervention effect In 1996 parasitism of sentinel leafhopper eggs was higher on vines with buckwheat than on vines with clover or sod.
- Intervention effect A similar but non-significant trend of higher parasitism on buckwheat vines was observed in 1997.
- Intervention effect Neither the abundance nor the distribution of leafhoppers was influenced by cover crops.
- Intervention effect In 1997 there was a trend toward greater numbers of leafhopper nymphs on edge vines with buckwheat.
- Intervention effect In a laboratory study, longevity of female Anagrus was increased when provided with honey or sugar water compared to water only or nothing.
- Intervention effect The authors suggest that parasitism of grape leafhoppers by Anagrus may be enhanced by providing floral resources within vineyards in New York.
