    Notes: Abstract Orfralure [93% (Z), 7% (E)-8-dodecen-1-ol acetate], the synthetic pheromone of the oriental fruit moth,Grapholitha molesta (Busck), was released into the air of orchard test plots either by hanging plastic laminated dispensers on trees or by aerial dispersal of microcapsules containing a solution of the lure. Trap catch was reduced 95% or more with the most effective formulations, but consistently higher reductions were produced by the dispensers. In tests as long as 28 weeks with dispensers, a single retreatment at midseason maintained an effective concentration.

    Notes: Abstract Volatile constituents of leaves of acceptable and unacceptable plants evoke multiunit responses from the antennal olfactory sensilla of larvae of the eastern tent caterpillar. Electrophysiological investigation of the activities of three of the sixteen antennal olfactory receptors revealed that different combinations of the three responded to the various plants. In those instances where the same combination responded to more than one species of plant, the ratios of responses measured as frequency of action potentials were often different. Thus, discrimination of different plants theoretically could be based upon the absolute number of cells responding and/or the ratios of frequencies.

    Notes: Abstract (Z)-11-Hexadecen-1-ol acetate (Z11–16∶Ac) free of theE isomer (〈1%), hexadecan-1-ol acetate (16∶ Ac), and a hexadecen-1-ol [the (Z)-11 isomer based on the retention time on a Carbowax capillary column] were identified in extracts of the sex pheromone glands of adult virgin female armyworms,Pseudaletia unipuncta. Also, gas Chromatographic retention times on polar and nonpolar columns indicated the possible presence of (Z)-9-hexadecen-1-ol acetate (Z9–16∶Ac). The ratioZ11–16∶Ac/16∶Ac/Z11–16∶OH/Z9–16∶Ac was 1∶0.15∶0.13∶0.02. Infield testsZ11–16∶ Ac was attractive alone, and the addition ofZ9–16∶Ac,Zll–16 ∶ OH, or 16 ∶ Ac singly or in combination in ratios found in the gland did not increase trap capture.

    Notes: Abstract Mixtures of (Z)-5- and (Z)-7-dodecenyl acetates in ratios 〉100∶1 are powerful, specific sex attractants for redbacked cutworm male moths. Bioactive lures were produced by admixture of these pure compounds or through syntheses involving catalytic bond shifting. Best field trapping was obtained with 200∶1 (Z)-5∶(Z)-7 ratio, at lure doses (on rubber) of 0.1–2.0 mg, using cone swivel traps with 10- to 13-mm orifices, or Pherocon® 1-CP sticky traps, at a height of 50–90 cm. The pheromone traps were more efficient than large blacklight traps and captured the various morphological forms of the moth in similar ratios.

    Notes: Abstract The sex pheromone of the woodbine leafroller,Sparganothis sp., includes (E)-11-tetradecen-1-ol, (Z)-11-tetradecen-1-ol, and (E)-11-tetradecen-1-yl acetate, based on chemical analysis of gland extracts, electroantennogram tests, and field trapping. Highest trap catches were obtained when these compounds were dispensed in the relative proportions observed in the female gland. (Z)-11-Tetradecen-1-yl acetate also was found in gland extracts, but significantly reduced trap catches. The saturated compounds tetradecan-1-ol and tetradecan-1-yl acetate were found in gland extracts as well, but were not tested. The amounts of these compounds per female gland were 127, 93, 17, 20, 25, and 3 ng, in the order named.

    Models for dispersal of vapors in open and confined spaces: Applications to sex pheromone trapping in a warehouse (1980)

    Notes: Abstract Methods are presented for mathematically determining dispersal of a vapor in still air, in turbulent air of zero average velocity, and in turbulent or laminar air currents of constant, nonzero average velocity. The methods are combined with several assumptions about insect behavior to derive an insect attraction model that predicts: (1) In a warehouse a searching insect is likely to be attracted to a calling insect if it comes within an attraction sphere, 0.4–2.5 m in radius. (2) The attraction spaces of typical sex pheromone-baited traps that emit pheromone at rates greater than 0.01 ng/sec extend beyond the boundaries of a 10 × 10 × 10-m warehouse. (3) The searching behavior of an attracted insect is likely to be altered from an extensive to an intensive pattern if it comes within an altered-behavior sphere, 6–60 cm from a calling insect or within 10 m of a trap emitting 0.76 ng/sec. (4) Pheromone does not sink unless it is emitted along with a large amount of a high-vapor pressure solvent. The model is used in support of several hypotheses, including: (1) The effect of an adsorptive surface on the vapor concentration after an extended period of emission is negligible except at positions near the surface. (2) Sex pheromone-baited traps with sources of small dimensions have greater trapping efficiency than otherwise identical traps with sources of large dimensions.

    Notes: Abstract Pheromone washes from calling female moths of redbacked cutworm,Euxoa ochrogaster (Guenée), contained the following acetates that are structurally similar to those of known lepidopteran pheromones (%): decanyl (8.7), dodecanyl (8.5), (E)-5-dodecenyl (3.3), (Z)-5-dodecenyl (76.4), (Z)-7-dodecenyl (3.1), and (Z)-9-dodecenyl (trace〈0.5%). This is the first time that (Z)-5-dodecenyl acetate has been identified as a pheromone component. Three types of specific receptor cells were found in the male antennae, and they responded to (Z)-5-decenyl acetate, (Z)-5- and (Z)-7-dodecenyl acetates, respectively. Strong electroantennographic detector responses were also recorded for these three acetates and for (Z)-5-undecenyl acetate. The evidence for the presence of (Z)-5-decenyl acetate in the pheromone washes was inconclusive. The presence of (Z)-7- and the absence of (Z)-8-dodecenyl acetates were confirmed by a special electroantennographic detector technique in which the detector antennae were from males of other species that were known to have strong responses to these acetates. This is a very useful technique. Field results show that low concentrations (0.1–1.3%) of (Z)-5-decenyl acetate were synergistic when tested in a previously reported blend, but 6% was inhibitory. Similarly, (Z)-7-dodecenyl acetate at 2% or less may be essential for the attraction of males, but in previous tests at 14% it also was inhibitory. Species-specific attractant blends for redbacked cutworm males are described.

    Notes: Abstract Benzaldehyde, phenylacetaldehyde (major component), 2-phenylpropenal,n-heptanal, 6-methylhept-5-en-2-one, and linalool were identified as compounds responsible for the male scent ofAtrophaneura alcinous alcinous. These substances were present predominantly in the wings, and the quantity of them was largest at the inner margin of the hind wing. Female wings also contained some of them in much smaller (except a few components) amounts. The relative proportion of each component exhibited manifests sexual differences.

    Anemotactic response threshold of the Indian meal moth,Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae), to its sex pheromone (1980)

    Notes: Abstract The effect of different concentrations of the sex pheromone (Z,E)-9,12-tetradecadien-1-ol acetate on the upwind anemotactic behavior of the malePlodia interpunctella (Hübner) was measured at 23 ± 1 ° C and 34 ± 1 ° C. The stimulus-response regression lines were analyzed by a new procedure that accounts both for control responses in the absence of pheromone and also for peak responses below 100% in the presence of concentrations considerably above the normal physiological levels. From the regression line for each temperature, the upwind anemotactic thresholds were calculated to be 1.34 × 106 molecules/cm3 at 23 ° C and 1.65 × 104 molecules/cm3 at 34 ° C, similar to other thresholds reported in the literature. Since departures from the two lines occurred at the highest concentrations tested, near 108 molecules/cm3, the upwind anemotactic behavior may change qualitatively above an altered-behavior threshold that is about two orders of magnitude higher than the upwind anemotactic threshold. The lower response at 23 ° C suggests that cool temperatures inhibit flight in response to pheromonal stimulation.

    Notes: Abstract During successful courtship in sulfur butterflies, virgin females respond to males by assuming a stationary posture and extending the abdomen ventrally from between the hindwings, thereby permitting copulation. In the clouded sulfur,Colias philodice Godard, this response was used in a laboratory bioassay to confirm the existence of a male chemical signal demonstrated by a previous worker and to document the signal's behavioral function and source. The male scent is shown to be required, in part, to reliably elicit abdominal extension and to be emitted from a patch of cells and scales associated with the dorsal surface of the male hind wing near the wing base. Experiments also show that evaporation of the signal is reduced when the source is covered by the forewing as it is at rest and in flight. These data, coupled with other information on male chemical signals in sulfur butterflies and other Lepidoptera, suggest that in sulfurs the morphology and chemistry of the scent glands along with the behavior of the male are structured in a way that minimizes the evaporative loss of scent from the wings when the male is not courting females.

    Notes: Abstract Trap capture data from Ohio and Wisconsin show that (E,Z)-3-13-octadecadien-1-ol acetate alone is an effective trap bait for maleSynanthedon pictipes (Grote and Robinson). Attractiveness increased by increasing attractant concentration but not by adding theZ,E geometrical isomer.S. pictipes males partitioned themselves in a linear fashion among traps baited with 10–100 μg of attractant in 10-μg increments. Furthermore, they discriminated between 50- and 100-μg baits placed in the same tree. These and other results indicate that, in clearwing experiments involving noninhibitory compounds and blend tuning, high trap density can be used successfully.

    Notes: Abstract Adult monarch butterflies,Danaus plexippus L. (Lepidoptera: Danaidae), store only some of the cardenolides present in the larval milkweed (Asclepiadaceae) host. Feeding known doses of individual cardenolides to 4th instar monarch larvae led to more efficient larval tissue incorporation at low doses than at high ones, and favored storage of cardenolide glycosides over genins. A qualitative regulation also occurs during larval feeding; calactin and calotropin were stored as such but uscharidin was rapidly converted to a mixture of calactin and calotropin which were the forms stored by the larvae. Two genins, uzarigenin and digitoxigenin, were stored by larvae as polar cardenolide metabolites.

    Notes: Abstract Methylene chloride-extractable chemical(s) from range caterpillar larval silk facilitates trail-following and aggregation by early-instar larvae, but late-instar larvae are less responsive to the pheromone. Larval aggregation does not reduce water loss when larvae are exposed to low humidity, nor does aggregation prevent predation by the antFormica neoclara Emery. Grouped larvae gain weight and complete early stadia more rapidly as compared to solitary larvae. Aggregation may provide increased visibility to herbivores and increase the impact of urticating spines, thereby decreasing inadvertant predation.

    Notes: Abstract Dodecyl acetate was identified as a second component of the sex pheromone ofTrichoplusia ni (Hübner). Dodecyl acetate comprised 9.6% by weight of the total pheromone [(Z)-7-dodecenyl acetate plus dodecyl acetate] extracted from glands and 7.3% by weight of the total pheromone evaporated from the surfaces of glands. Dodecyl acetate appears to function as a short-range pheromone component. Evaporation at female release rates of a 10∶90 mixture of dodecyl acetate and (Z)-7-dodecenyl acetate in the field caused a significantly greater percentage of males to land on the pheromone source, increased significantly the time they spent on the source, but decreased significantly the time they spent searching for the source when within 50 cm, as compared to (Z)-7-dodecenyl acetate alone.

    Notes: Abstract The release rates of (Z)-9-tetradecen-1-ol formate (Z9TDF) from four sizes of polyethylene tubing were measured periodically for 50 days by collecting the Z9TDF vapors on a polymeric adsorbent. The resulting release rate curves had shapes that were determined by the tubing's diameter and wall thickness. One tubing size that combined good longevity with adequately high release rates was tested in the field to determine whether it could disrupt pheromone communication of the corn earworm,Heliothis zea (Boddie). We observed a low percentage of disruption, but release rate measurements made concurrently showed that the tubing was releasing Z9TDF normally. In a second field test, a larger quantity of Z9TDF was released, and 87% disruption was attained for 66 days.
