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.

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.

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.

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.

AbstractField testing of a large number of synthetic compounds and two-component combinations thereof revealed an attractant for the adult males of Leucania commoides Guenée. Several three-component combinations were tested and the largest numbers of L. commoides males were attracted to Z-9-tetradecen-1-yl acetate, Z-11-hexadecen-1-yl acetate, and Z-11-hexadecen-1-ol in ratios of 4:4:1 to 10:5:2. The attraction of this species was inhibited by Z-9-tetradecen- 1-ol.

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.

Crymodes Devastator

We reported previously (Steck et al. 1977) that equal-parts mixtures of (Z)-11-hexadecenal (Z11-16:Ald) and (Z)-11-hexadecenyl acetate (Z11-16:Ac) attract male Crymodes devastator (Brace) moths to field traps, and that attraction is enhanced by incorporation of (Z)-7-dodecenyl acetate (Z7-12:Ac) in the lure. During subsequent studies with sex lures for this species we discovered that (Z)-11-hexadecenol (Zll-16:OH) is much more effective than Z7-12:Ac as a trapping synergist.During 1978 many structural analogs of the sex attractant components were tested as lure synergists by adding 20% of each analog to a basic 2:l Z11-16:Ald + Z11-16:Ac lure, using numbers of males trapped as the criterion of effect. Z5- and Z7-10:Ac; Z5-, Z7-, and Z9-12:Ac; Z5-, Z7-, Z9-, and Z11-14:Ac; Z5-, Z7-, and Z9-16:Ac were tested in this way, as were the corresponding alcohols and aldehydes and Zll-16:OH. The (E) isomers of these along with Ell-16:Ald and E11-16:Ac were finally tested.
