“…The edge effects in grape cane gallmaker density observed at sites 1, 2, and 4 are consistent with results obtained for other native insect herbivores using Vitis, such as the grape berry moth, Endopiza viteana (Clemens) (Lepidoptera: Tortricidae) (Sanders and DeLong 1921, Hartzell 1929, Hoffman and Dennehy 1989. Edge effects may arise when grape cane gallmaker use wild Vitis, which ßourish along woodland margins, as native hosts.…”

The grape cane gallmaker, Ampeloglypter sesostris (Leconte), is a native weevil that infests new shoots of wild and cultivated grapes (Vitis spp.). Females oviposit on the tender portions of new shoots, producing a reddish gall that can expand the shoot to twice its normal diameter. These galls can be quite numerous in eastern vineyards, and their effects are unknown. We studied the spatial distribution of grape cane gallmaker and its impact on berry size, sugar content, and nutrient and mineral uptake. We observed spatial trends in grape cane gallmaker distribution in vineyards adjacent to woodland margins, with the trend emanating from the woodline. In vineyards without woodland margins, there was little spatial dependency in grape cane gallmaker distribution in individual years. However, grape cane gallmaker density on a single vine was spatially cross-correlated between 2 yr. The presence of galls did not significantly affect berry quality, or the uptake of nutrients and minerals, and we conclude that grape cane gallmaker does not negatively impact berry quality or mature vine vigor.

“…pheromone and insecticide plots, 30 August and 28 September) (Tables 5 and 6). The occurrence of higher levels of infestation along vineyard borders is well known for E. viteana in insecticide-treated vineyards (Sanders and DeLong 1921;Garlick 1934;Biever and Hostetter 1989;Hoffman and Dennehy 1989) and the phenomenon has been observed in west European vineyards treated with pheromone to control E. ambiguella (Englert 1985;Vogt and Schropp 1985;Charmillot et al 1987). Sanders and DeLong (1921) attributed the "border effect" to a higher level of E. viteana overwintering survival along vineyard borders and Hoffman and Dennehy (1989) attributed the border effect to the dispersal of moths from wild hosts, i.e.…”

POTENTIAL OF MATING DISRUPTION USING SEX PHEROMONE FOR CONTROLLING THE GRAPE BERRY MOTH, ENDOPIZA VITEANA (CLEMENS) (LEPIDOPTERA: TORTRICIDAE), IN NIAGARA PENINSULA, ONTARIO VINEYARDS

The efficacy of mating disruption for controlling the grape berry moth, Endopiza viteana (Clemens) (Lepidoptera: Tortricidae), was evaluated from 1987 to 1989 in the Niagara peninsula, Ont. Mating disruption was tested in commercial vineyards with high-, moderate-, and low-density grape berry moth populations using the Biocontrol Ltd. tape-type and wire-type pheromone dispensers. Pheromone-baited trap catches were reduced by 92% or more in plots treated with pheromone. Treatment with pheromone significantly reduced damage (percentage infested clusters) compared with an untreated control in each of two tests, and provided control as good as or better than an insecticide control programme in two of four tests. Damage increased from 1.3- to 12.8-fold between successive generations in plots treated with pheromone, and was greater on the borders of some plots treated with pheromone or insecticide. It is concluded that mating disruption may have potential as a control method for use in the integrated management of E. viteana.

“…Although parasitoid massproduction costs are lower in China (100 000/0.06 USD) than the United States of America (100 000/2.43 USD) (Greenberg et al 1998), the cost of parasitoid establishment in the United States of America and Canada could be greatly reduced by confining releases to border rows and vineyard edges, particularly those adjacent to wooded areas where wild Vitis spp. serves as host refuges and where grape berry moth abundance is generally the greatest (Sanders and DeLong 1921;Hoffman and Dennehy 1989). In this paper, we report on the effects of releases of T. minutum on grape berry moth damage to grapes over 4 years in the Lake Erie grape-growing region.…”

Release of native Trichogramma minutum to control grape berry moth

et al. 2003

We studied the effects of inundative releases of the egg parasitoid Trichogramma minutum Riley (Hymenoptera: Trichogrammatidae) on economic injury by grape berry moth, Endopiza viteana (Clemens) (Lepidoptera: Tortricidae). Trichogramma minutum originally collected from natural host populations near North East, Pennsylvania, was mass produced in tobacco hornworm hosts and Mediterranean flour moth. We released T. minutum in border rows, where grape berry moth infestation is typically high, of experiment field station and commercial vineyards from 1996 to 1999. We recorded significant reductions in economic injury in plots where parasitoids were released. In vineyards with low to moderate grape berry moth abundance, four releases during the growing season were adequate in reducing damage at harvest to below 3%. In high-risk vineyards, T. minutum releases reduced damage to levels below 15%. The use of buckwheat as a cover crop to provide nectar in combination with parasitoid releases showed potential benefits in parasitoid activity. A biocarrier and Biosprayer™ were used in mechanized parasitoid-release operations, and no adverse effect on parasitoid emergence was recorded from parasitized eggs using this approach.
