“…The different generation ßights of grape berry moth should be predictable based on temperature and degree-day accumulations. Based on growth chamber experiments Tobin et al (2001) estimated a lower developmental threshold of 8.9ЊC and Ϸ410 DD to go from egg to adult female. grape berry moth females typically do not begin laying eggs for 3Ð 4 d after eclosion in the lab at a constant 23ЊC.…”

For some Lepidopteran pests, such as the grape berry moth Paralobesia viteana (Clemens), poor correlation between males captured in traps baited with sex pheromone and oviposition activities of female moths has called into question the value of pheromone-based monitoring for these species. As an alternative, we compared the capture of female and male grape berry moth in panel traps baited with synthetic host volatiles with captures of males in pheromone-baited wing traps over two growing seasons in two blocks of grapes in a commercial vineyard in central New York. Lures formulated in hexane to release either 7-component or 13-component host volatile blends captured signiÞcantly more male and female grape berry moth on panel traps compared with the numbers captured on panel traps with hexane-only lures. For both sexes over both years, the same or more moths were captured in panel traps along the forest edge compared with the vineyard edge early in the season but this pattern was reversed by mid-season. Male moths captured in pheromone-baited wing traps also displayed this temporal shift in location. There was a signiÞcant positive correlation between captured males and females on panel traps although not between females captured on panel traps and males captured in pheromone-baited traps for both years suggesting pheromone traps do not accurately reßect either female or male activity. Male moths captured in pheromone traps indicated a large peak early in each season corresponding to Þrst ßight followed by lower and variable numbers that did not clearly indicate second and third ßights. Panel trap data, combining males and females, indicated three distinct ßights, with some overlap between the second and third ßights. Peak numbers of moths captured on panel traps matched well with predictions of a temperature-based phenology model, especially in 2008. Although effective, panel traps baited with synthetic host lures were time consuming to deploy and maintain and captured relatively few moths making them impractical, in the current design, for commercial purposes.

The effect of temperature on the development of the predators Nephus includens (Kirsch) and N. bisignatus (Boheman) (Coleoptera: Coccinellidae), was studied. The development time of immature stages and the pre-oviposition period of adult females for the two predators was recorded at eight constant temperatures (10, 15, 20, 25, 30, 32.5, 35 and 37.5°C). The beetles were reared on eggs, nymphs and female adults of Planococcus citri (Risso) (Homoptera: Pseudococcidae) that had developed on squash (Cucurbita pepo) and on sour orange leaves (Citrus aurantium). Using the linear mode! for the biological cycle of N. includens on squash and on sour orange leaves, the developmental zeros (lower temperature thresholds) were estimated to be 10.9 and 11.0°C respectively and the thermal constants, 490.5 and 472.8 day-degrees respectively. Using the Lactin model the lower thresholds were estimated to be 11.1 and II.2°C respectively and the upper thresholds 36.1 and 36.0 U C respectively. For the biological cycle of N. bisignatus, using the linear model, the lower thresholds were estimated to be 9.4°C on squash and 9.3°C on sour orange leaves and the thermal constants were 614.3 and 647.9 day-degrees respectively. Using the Lactin model the lower thresholds were estimated to be 9.9 and 10.0"C respectively and the upper thresholds, 34.7 and 35.0"C respectively. The survival rate of N. includens instars at 10, 15, 20, 25, 30, 32.5, 35 and 37.5°C on squash and on sour orange leaves was respectively 0, 34.9, 63.2, 70.6, 63.3, 54.5, 19.8, 0, and 0, 32.2, 61.0, 68.0, 68.3, 56.6. 17.6, 0%. The survival rate of N. bisignatus instars at 10, 15, 20, 25, 30, 32.5 and 35°C on squash and on sour orange leaves was respectively, 0, 39.9, 61.1, 60.7, 47.2, 26.4, 0 and 0, 35.7, 65.7, 68.0, 44.2, 29.1, 0%. The results show that N. includens has a shorter biological cycle than N, bisignatus, whereas the latter species has lower temperature thresholds.
