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.

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.

AbstractField testing of a large number of synthetic compounds and several combinations of them revealed that male moths of the darksided cutworm, Euxoa messoria (Harris), were attracted to combinations of Z-7-hexadecen-1-yl acetate and Z-11-hexadecen-1-yl acetate. The most satisfactory attractants were combinations of these two compounds in ratios of 1:20 or 1:40. The presence of small amounts of the corresponding E-isomers did not interfere with the attractant. The diene, Z-7, Z-11-hexadecadien-1-yl acetate, in combination with Z-11-hexadecen-1-yl acetate also attracted the males, but there was no advantage in using the diene in place of Z-7-hexadecen-1-yl acetate.

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.

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.

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.
