Male Fishia yosemitae (Grote) (Lepidoptera: Noctuidae) Captured in Traps Baited with Z-7-dodecenyl Acetate and Z-9-tetradecenyl Acetate

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.

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.

Bertha Armyworm

AbstractInclusion of traces of (Z)-11-hexadecenol in synthetic sex lure traps for bertha armyworm moths resulted in diminished trapping; substantial amounts of (Z)-9-hexadecenol or (Z)-11-hexadecenal were also suppressant. Of 22 other oxyolefins tested, (Z)-7-dodecenyl acetate acted in conjunction with the bertha lure components to attract Euagrotis tepperi (Walker) to traps, and (Z)-7-tetradecenyl acetate similarly to attract Lacinipolia vicina (Grote). No tested additive improved either the potency or the specificity of the original bertha blend.

AbstractThe courtship of Spodoptera littoralis (Boisd.) was studied in closed cages containing an excess of the female sex pheromones (Z,E)-9, 11-tetradecadienly acetate (III) or (Z)-9-tetradecenyl acetate (IIA). High levels of III or IIA were obtained by using polyethylene vials loaded with 5, 1 or 0·1 mg of pheromone. Vials containing 10 or 1 μg released low levels of pheromone. Excess pheromone reduced mating; at high levels of III and IIA, only 15% and 42% of pairs, respectively, mated, compared with 92% of control pairs. Some 45% of courtships in control cages did not end in copulation, and in half of these the female rejected the male by giving a rapid flick of the wings. A detailed examination of unsuccessful courtships showed that an excess of III or IIA disrupted female courtship behaviour. At the higher levels of pheromone, no female wing-lifted to show acceptance of the male and only a few rejected the male by wing-flicking. Significantly more females took to flight in cages containing III, whilst in cages with IIA females either took to flight or remained still. These changes in behaviour were still apparent in courtships where the female was calling and the male gave a full brush display. It is suggested that both III and IIA block olfactory reception of the male brush pheromone. An excess of either pheromone increased the proportion of male courtships of non-calling females. IIA had no other appreciable effect on male behaviour, but III also significantly reduced full brush displays during courtship, increased the period of flight preceding hovering and increased partial brush extension during flights that did not lead to courtship.

AbstractPheromone traps were more efficient than blacklight traps for detecting and monitoring adult populations of fall armyworm, Spodoptera frugiperda (J.E. Smith), in southwestern Ontario. Several dispenser–chemical combinations were strongly attractive but best results were obtained with sticky traps baited with rubber septa impregnated with combinations of (Z)-9-dodecenyl acetate and (Z)-9-tetradecenyl acetate.
