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.

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.

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.

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.

AbstractField trapping of Diachrysia chrysitis and D. tutti by sex-attractants was carried out in different parts of Sweden and Finland in 1985-1988. Allozyme electrophoresis and wing pattern analysis suggest that D. tutti is a separate species occurring sympatrically with D. chrysitis in the study area. Whether the great similarity between the samples was due to gene flow between species or specimens being trapped by the other species' sex-attractant is still an open question.

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.

Abstract The sex-attractant system of the dart moth Agrotis exclamationis (L.) (Noctuidae) was re-investigated with electrophysiological and field trapping tests. The identified pheromone components (Z)-5-tetradecenyl acetate and (Z)-9-tetradecenyl acetate elicited maximum trap captures when combined in a Z5-/Z9-mixture ratio of between 100/10 and 100/20, in contrast to an earlier reported mixture optimum of 100/5. Each compound activated a particular type of receptor cell located in the male antennal hair sensilla. Three further cell types discovered in these sensilla responded specifically to the non-pheromonal compounds (Z)-7-dodecenyl acetate and (Z)-7-and (Z)-11-tetra-decenyl acetate. These latter compounds did not show attractive or synergistic properties in field trapping tests but rather reduced captures when added to the binary pheromone blend as a third component. The biological functions of these three “attraction-inhibitors” remain unidentified.

Abstract Binary combinations of (Z)-7-dodecenyl acetate and (Z)-9-tetradecenyl acetate in a 1/10 ratio were highly attractive to Rh. baja males in field trapping tests conducted in southern Germany. Trap captures increased further on adding 0.1 or 0.3% of (Z)-5-dodecenyl acetate to this lure; higher amounts of this chemical were strongly inhibitory, as were additions of > 3% of (Z)-11-hexa-decenyl acetate. The trapping data are considered in terms of electrophysiological responses of five types of antennal receptor cells.

Pheromonal synergism and inhibition in P. flammea was further studied through electrophysiological and field trapping tests. Z11-tetradecenyl acetate and Z11-hexa - decenyl acetate, each acting upon a separate type of male sensory cell, were equally effective in synergizing attraction responses to the major pheromone component, Z9-tetradecenyl acetate. Addition of Z7-dodecenyl acetate to these lures reduced captures. Male attraction specificity markedly varied with local moth density.
