The status and distribution of ants in the Crater District of Haleakala National Park The status and distribution of ants in the Crater District of Haleakala National Park
The Crater District of Haleakala National Park was surveyed for ants. Three species were found. Argentine ants (Iridomyrmex humilis) occurred only within I km of the park headquarters and the nearby research facility. Hypoponera opaciceps was found in small numbers throughout the Crater District. Cardiocondyla emeryi was present only at the head of Kaupo Gap. Possible impacts of these...

Mesurol as a bird repellent on wine grapes in Oregon and California Mesurol as a bird repellent on wine grapes in Oregon and California
Field tests were conducted in California and Oregon from July to October 1978 to evaluate the effectiveness of Mesurol as a repellent to reduce bird damage to ripening wine grapes. A block of vines composed of two similar, adjacent plots was delineated at each of 20 vineyards. One randomly chosen plot within each block was treated with up to three applications of Mesurol (75% wettable...

Estimating bird damage from damage incidence in wine grape vineyards Estimating bird damage from damage incidence in wine grape vineyards
Bird damage was measured during 1977 and 1978 at 32 wine grape vineyards in the San Joaquin Valley and North Coastal Region of California. Both the percentage bird loss (PBL) and the percentage of bunches damaged (BDI = bird damage incidence) were determined during 55 total-damage assessments, and the resulting data pairs were used to develop a regression of PBL on BDI. The final...
