AbstractLarvae of Abagrotis orbis (Grote) (Lepidoptera: Noctuidae) are climbing cutworms and can damage grapevines, Vitis vinifera L. (Vitaceae), in early spring by consuming expanding buds. A sex attractant would be useful for monitoring this insect in commercial vineyards. (Z)-7-Tetradecenyl acetate and (Z)-11-hexadecenyl acetate were found in extracts of female abdominal tips. In multiple field experiments, male A. orbis were captured in traps baited with a combination of these two chemicals but not in traps baited with either chemical alone. Males were trapped from mid-September to early October in south-central Washington and south-central British Columbia. Other noctuid moths (Mamestra configurata Walker, Xestia c-nigrum (L.), and Feltia jaculifera (Guenée)) were also captured in traps baited with the A. orbis pheromone and may complicate the use of this lure to monitor A. orbis. Abagrotis discoidalis (Grote) was captured in traps baited with (Z)-7-tetradecenyl acetate but not in traps baited with the two chemicals together.

Electrophysiological analysis of olfactory hair sensilla in male P. pisi has revealed four different types of presumed pheromone receptor cells, maximally responsive to (Z)-11-tetradecenyl acetate (Z11-14:Ac), (Z)-9-tetradecenyl acetate (Z9-14:Ac), (Z)-11-hexadecenyl acetate (Z11-14:Ac) and (Z)-7-dodecenyl acetate (Z7-12: Ac), respectively. These four compounds were tested, singly and in various combinations, for efficacy in attracting P. pisi males in the field. High trap catches were obtained with mixtures of Z11-14: Ac/Z9-14: Ac in the ratio 100/100, whereas the 100/30 and 30/100 mixtures of the two compounds were only slightly attractive. No male P. pisi were captured by single chemicals or binary combinations of Z11-14: Ac/Z11-16: Ac, Z11-14:Ac/Z7-12:Ac, Z9-14:Ac/Z11-16:Ac, Z9-14:Ac/Z7-12:Ac, or Z11-16:Ac/Z7-12:Ac. Various compounds, including Z11-16: Ac and Z7-12:Ac, were tried as third chemicals in addi­tion to 100 μg Z11-14: Ac + 100 μg Z9-14: Ac but none increased trap catches over the basic lure.

The strawberry cutworm, Amphipoea interoceanica (Smith), has recently become an important pest of strawberry plants in Manitoba (Ayre 1980) and Quebec (Mailloux and Bostanian 1985). Larvae damage or kill the plants and commercial plantings are sometimes heavily damaged. Strawberry cutworm is widely distributed in North America and is broadly sympatric with a morphologically similar species, Amphipoea americana (Speyer) (Forbes 1954), which is occasionally a pest of corn (Gibson 1920). Sex pheromones of these species have not been reported, although Roelofs and Comeau (1971) found that males of strawberry cutworm were attracted to (Z)-9-tetradecenyl acetate (abbrev. Z9- 14:Ac). A sex attractant for strawberry cutworm would provide a convenient method for monitoring population levels in the vicinity of strawberry fields.

Lures for a monitoring system based on sex attractant trapping of Agrotis segetum males were elaborated for Israel and Germany. Various mixtures of (Z)-5-aecenyl acetate, (Z)-7-dodecenyl acetate, (Z)-9-dodecenyl acetate, (Z)-9-tetradecenyl acetate, decyl acetate and dodecyl acetate were tested in 20 different blends. From comparison of all the trap catches a four-component lure consisting of (Z)-5-decenyl, (Z)-7-dodecenyl, (Z)-9-tetradecenyl and dodecyl acetate is recommended for monitoring of A. segetum in both countries.

In field trapping tests male Orthosia gothica (Lepidoptera: Noctuidae) were captured in traps baited with blends of (Z)-9-tetradecenyl acetate, (Z)-9-tetradecenol, (Z)-5-tetradecenyl acetate and (Z)-l 1-tetradecenyl acetate. The highest catches were recorded in traps baited with a 20:20:1:1 blend. The above quaternary blend is a potent sex attractant of this species, and it can be recommended in dosages of 10-100 μg per dispenser for monitoring purposes.

AbstractMale moths of striped cutworm, Euxoa tessellata (Harris), were specifically attracted to blends of Z-5-tetradecenyl acetate or Z-5-hexadecenyl acetate with Z-7-hexadecenyl acetate. The most satisfactory quantities of these components per septum dispenser were: Z-5-tetradecenyl and Z-7-hexadecenyl acetates at 2.5 and 500 μg, or Z-5-hexadecenyl and Z-7-hexadecenyl acetates each at 500 μg. The addition of 1.0% Z-7-hexadecenol relative to Z-7-hexadecenyl acetate in either of these blends inhibited the attraction of males. The blend involving Z-5-tetradecenyl acetate is recommended for monitoring purposes.

AbstractEighteen species of cutworm moths were collected as larvae feeding at night on grapevines, Vitis sp. L. (Vitaceae), in south-central British Columbia, Canada, during April and May from 2004 to 2008. Ten species belonged to two genera, Abagrotis Smith and Euxoa Hübner. Abagrotis orbis (Grote), A. nefascia (Smith), and A. reedi Buckett accounted for over 85% of cutworms reared to adulthood. Abagrotis orbis and A. reedi were found in all locations; the former accounted for nearly 90% of larvae collected from vineyards on warm sandy soils. Abagrotis nefascia was largely restricted to cooler sites with heavier soils. For laboratory-reared A. orbis, pupal mass was highest and sex ratios were approximately equal when larvae were reared either on a pinto bean-based diet prepared with the recommended amount of water or on a commercial black cutworm diet and 50% of the recommended water. Survival to adult eclosion was significantly higher on the black cutworm diet, but because this was thicker than the pinto bean-based diet it was impractical to use. To date, A. orbis, A. nefascia, and A. reedi have been laboratory-reared continuously on artificial diet for more than six generations.

AbstractThe sex pheromone components of the black army cutworm, Actebia fennica (Tauscher), were identified in abdomen-tip extracts from calling female moths. The primary pheromone component was (Z)-7-dodecenyl acetate. Although (Z)-11-tetradecenyl acetate was detectable only in trace quantities in the extracts, it was the major component in the best synthetic blend for attraction of male moths. The most effective synthetic blend was (Z)-7-dodecenyl acetate and (Z)-11-tetradecenyl acetate at a ratio of 1:20. No other component detected in the extracts increased trap capture of males when added to the two-component blend; however, (Z)-5-dodecenyl acetate, (Z)-7-dodecenol, and (Z)-9-tetradecenyl acetate reduced catches. This two-component blend will be useful for studying the habits of the adults and for population monitoring.

Antennal Responses

AbstractAdult Euxoa tristicula (Morrison) males were specifically attracted to traps baited with Z-9-dodecenyl acetate (Z9-12:Ac) + n-dodecyl acetate (12:Ac). Best attractancy was obtained with 1:3 ratios of these components. Z-5- and Z-7-dodecenyl acetates and Z-9-tetradecenyl acetate inhibited lure attractancy. In electroantennogram measurements strong antennal responses were obtained only with 12:Ac, Z9-12:AC, and E9-12:Ac.

AbstractEmergence, oviposition, and seasonal flight activity of adult, speckled green fruit worm, Orthosia hibisci Guenée (Lepidoptera: Noctuidae), were monitored during 1991 and 1992 in a mixed block of McIntosh and Spartan apple trees at Summerland, British Columbia, to establish relationships between the phenology of these events and degree-days (DD). Using air temperatures and a developmental threshold of 3 °C, median emergence of males was predicted most accurately (0–2 days) by starting DD summations on 1 March. Median emergence of females was predicted without error when first catch of a male in a trap baited with sex attractant was used as a population reference point (biofix) to start DD summation. Using a threshold temperature of 3 °C, observed cumulative emergence of females reached 50% at 63.5 ± 4.05 DD3 °C after biofix, similar to the laboratory-derived prediction of 61.3 ± 4.2 DD with a threshold temperature of 2.8 °C. Catches of males with sex attractant preceded oviposition, but female catches in light traps lagged behind oviposition, suggesting older females were being caught in light traps. The oviposition curve was linear and parallel to the cumulative curve of male catches with sex attractant. Oviposition began at 26.7 DD3 °C and reached 50% at 94.2 DD3 °C after biofix, respectively. Weibull equations fitted to observed cumulative catches with sex attractant, female emergence, and oviposition, combined with laboratory-derived DD models of egg and larval development, were used to predict phenology of O. hibisci and correlate it with flowering phenology of pome fruits. This study provides a basis for timing application of selective insecticides against O. hibisci based on first catch in a sex-attractant trap and DD summations.
