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.

The white cutworm, Euxoa scandens (Riley), is a sporadic pest of tobacco in Quebec (Mailloux and Desrosiers 1978), asparagus in Michigan (A. L. Wells, pers. comm.), and other vegetable crops grown in light sandy soils (Beirne 1971). The immature larvae overwinter and cause serious damage when they resume feeding in the spring (Hudson and Wood 1930). Moths emerge and oviposit from late June until late July (McLeod and Dupré 1981). An efficient monitoring method utilizing the female sex pheromone would be an important aid in estimating the size and distribution of the adult population and would help in planning insecticide control. We report here some results of electroantennogram screening of potential sex attractants and the results of field tests of the most active of these.

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.

AbstractSex attractant traps for males of the clover cutworm, Scotogramma trifolii (Rottenberg), on farms in southern Alberta caught more moths within crops or on fallow than those near or within the farmyards except for traps immediately on the south side of the yard For males of the army cutworm, Euxoa auxiliaris (Grote), two trap placements in open areas were more effective than locations within the farmyard, again with the exception of the traps on the south side of the yards. Traps 2 m high caught significantly fewer moths than those at 1 m or ground level and the crop in which the trap was placed had no significant influence on catch of either cutworm.

AbstractField testing of a large number of synthetic compounds and many combinations of them revealed that male moths of the pale western cutworm, Agrotis orthogonia Morrison, were attracted to combinations of Z-5-dodecen-1-yl acetate and Z-7-dodecen-1-yl acetate. The most satisfactory attractants were combinations of these two compounds in ratios of 1:2 to 1:5 at 10 to 25 μg/septum dispenser. The effect of the attractant was strongly inhibited by the addition of 21% Z-7-dodecen-1-ol.

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.
