Dunkelblum, Ezra published the artcileSex attractant blends for field trapping of Agrotis segetum males (Lepidoptera: Noctuidae) in Israel and Germany, Recommanded Product: (Z)-Dodec-9-en-1-yl acetate, the publication is Zeitschrift fuer Naturforschung, C: Journal of Biosciences (1985), 40C(3-4), 272-7, database is CAplus.

Lures for a monitoring system based on sex attractant trapping of A. segetum males were elaborated. Various mixtures of (Z)-5-decenyl acetate  [67446-07-5], (Z)-7-dodecenyl acetate  [14959-86-5], (Z)-9-dodecenyl acetate  [16974-11-1], (Z)-9-tetradecenyl acetate  [16725-53-4], decyl acetate  [112-17-4] and dodecyl acetate  [112-66-3] were tested in 20 different blends. From comparison of all the trap catches, a 4-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.

Hellmann, Christoph published the artcileDesign of pheromone releasing nanofibers for plant protection, Name: (Z)-Dodec-9-en-1-yl acetate, the publication is Polymers for Advanced Technologies (2011), 22(4), 407-413, database is CAplus.

Plants tend to attract diseases quite similar to human beings. Pesticides tend to be used to control such diseases. An alternative route, at least as far as damages from insects is concerned, envisions the application of pheromones. These cause a disorientation of male insects so that they are no longer able to locate the females, which finally gives rise to suppression of reproduction The approach considered in this paper is based on the release of pheromones from polymer carriers, in particular, from nanofibers webs as obtained by electrospinning. These may be distributed across the field quite similar to spider webs. The pheromones are required to be incorporated in sufficiently high concentrations in the nanofibers via electrospinning and to be released from the nanofibers for a sufficiently long time expanding over several weeks to months. Polyamide 6 as well as cellulose acetate was used as a polymer carrier in the investigations reported in this contribution. Studies reveal that fluid pheromones can, in fact, be incorporated in the nanofibers to more than 33 weight%. They may undergo a nanoscalar phase separation within the fibers during electrospinning. Furthermore, thermogravimetric studies revealed via in vitro release studies that the pheromones are released from the nanofibers in a nearly linear fashion over a period covering many weeks.

Chansang, Arpaporn published the artcileSynergy in the adulticidal efficacy of essential oils for the improvement of permethrin toxicity against Aedes aegypti L. (Diptera: Culicidae), COA of Formula: C14H26O2, the publication is Parasites & Vectors (2018), 417/1-417/16, database is CAplus and MEDLINE.

In a previous screening program for mosquitocides from local edible plants in Thailand, essential oils (EOs) of Cyperus rotundus, Alpinia galanga and Cinnamomum verum, were found to possess promising adulticidal activity against Aedes aegypti. With the aim of reducing usage of conventional insecticides and improving the management of resistant mosquito populations, this study was designed to determine the potential synergism in the adulticidal efficacy of EOs on permethrin toxicity against Ae. aegypti, both pyrethroid-resistant and -susceptible strains. EOs extracted from rhizomes of C. rotundus and A. galanga as well as C. verum barks were evaluated for chem. compositions and adulticidal activity against Muang Chiang Mai-susceptible (MCM-S) and Pang Mai Dangresistant (PMD-R) strains of Ae. aegypti. Adulticidal bioassays of EO-permethrin mixtures for synergistic activity were also performed on these Ae. aegypti strains. Chem. characterization by the GC-MS anal. technique demonstrated that 48 compounds were identified from the EOs of C. rotundus, A. galanga and C. verum, representing 80.22%, 86.75% and 97.24%, resp., of all compositions Cyperene (14.04%), β-bisabolene (18.27%) and cinnamaldehyde (64.66%) were the main constituents of C. rotundus, A. galanga and C. verum oils, resp. In adulticidal bioassays, EOs of C. rotundus, A. galanga and C. verum were effective in killing Ae. aegypti, both MCM-S and PMD-R strains, with LD₅₀ values of 10.05 and 9.57μg/mg female, 7.97 and 7.94μg/mg female, and 3.30 and 3.22μg/mg female, resp. The adulticidal efficacy against MCM-S and PMD-R Ae. aegypti of these EOs was close to that of piperonyl butoxide (PBO, LD₅₀ values = 6.30 and 4.79μg/mg female, resp.) but less pronounced than that of permethrin (LD₅₀ values = 0.44 and 3.70 ng/mg female, resp.). Nevertheless, combination-based bioassays discovered the accomplished synergism of EOs together with permethrin. Significant synergistic effects with permethrin against both the strains of Ae. aegypti were recorded in the EOs of C. rotundus and A. galanga. Addition of C. rotundus and A. galanga oils decreased the LD₅₀ values of permethrin against MCM-S dramatically from 0.44 to 0.07 and 0.11 ng/ mg female, resp., with synergism ratio (SR) values of 6.28 and 4.00, resp. Furthermore, EOs of C. rotundus and A. galanga also reduced the LD₅₀ values of permethrin against PMD-R drastically from 3.70 to 0.42 and 0.003 ng/mg female, resp., with SR values of 8.81 and 1233.33, resp. The synergy of enhanced adulticidal toxicity recorded from EO-permethrin combinations against both strains of Ae. aegypti presents a promising role of EOs as a synergist for improving mosquitocidal efficacy, particularly in situations where conventional compounds are ineffective or inappropriate.

Ioriatti, C. published the artcileStudy of the principal factors influencing the emission of synthetic sex attractants from rubber and plastic diffusers, Recommanded Product: (Z)-Dodec-9-en-1-yl acetate, the publication is Entomologia Experimentalis et Applicata (1987), 44(2), 123-30, database is CAplus.

To determine the effect of various factors influencing the emission rate of pheromones from slow release dispensers, laboratory tests were undertaken with two types of rubber (Michelin) and one type of plastic trilaminate (Hercon) dispenser. The effects of chain length, and the presence of double bonds were tested with three pheromonal compounds, (Z)-9-dodecenyl acetate, (Z)-9-tetradecenyl acetate, and dodecenyl acetate impregnated on both types of rubber dispenser. The influences of temperature, wind velocity, humidity and percent loading were also tested. Data obtained indicated that chain length has a greater effect than the presence of a double bond. Among the climatic factors tested, wind speed has a greater effect than temperature while humidity has a minimal effect.

Linn, C. E. Jr. published the artcileMale moth sensitivity to multicomponent pheromones: critical role of female-released blend in determining the functional role of components and active space of the pheromone, Recommanded Product: (Z)-Dodec-9-en-1-yl acetate, the publication is Journal of Chemical Ecology (1986), 12(3), 659-68, database is CAplus and MEDLINE.

Male redbanded leafroller (Argyrotaenia velutinana), cabbage looper (Trichoplusia ni), and Oriental fruit moths, (Grapholita molesta) were tested in a flight tunnel for responses to (1) the major pheromone component, (2) the Z/E pheromone component mixtures for Oriental fruit moth and redbanded leafroller, and (3) and the female-released blends, over a series of dosages. Experiments were designed to test the hypothesis that male response downwind of a female is initiated by the major component and that minor components function only to elicit behaviors close to the female during close-range approach and courtship. The results did not support this hypothesis, but rather showed that males initiated upwind flight in significantly higher percentages to the complete blends of components, at all dosages, compared to single components or partial blends. Addition of minor components also significantly enhanced male perception of the major component at lower dosages, resulting in completed flights to dosages of the major component that alone did not elicit any upwind flight. Thus, minor components apparently function to enhance male sensitivity to the pheromone, and the specificity of the signal. Also, the active space of the pheromone is apparently a function of the upper and lower concentration thresholds for the blend of components, and not simply for the major component.

McDonough, L. M. published the artcileInsect sex pheromones. Effect of temperature on evaporation rates of acetates from rubber septa, Application of (Z)-Dodec-9-en-1-yl acetate, the publication is Journal of Chemical Ecology (1989), 15(3), 779-90, database is CAplus and MEDLINE.

The half-lives (t_1/2) for evaporative loss of n-alkyl and n-alkenyl acetates from rubber septa were determined at 15-35°. The changes in t_1/2 with temperature gave a high correlation with the equation ln t_1/2 = ΔH/RT + y₀, where ΔH is the heat of vaporization, R is the gas constant, T is the absolute temperature, and y₀ is a constant Half-lives changed dramatically with temperature and the degree of change with temperature increased with increasing mol. weight For mixtures, component ratios changed with temperature, but the degree was modest. At 20° there was a 7.5-fold ratio of t_1/2 between members of the homologous n-alkyl or n-alkenyl acetates differing by two carbon atoms. The large change in t_1/2 with temperature and with number of carbon atoms is a consequence of the thermodn. relationships and the temperature range of pheromone usage. Therefore, a similar degree of changes in t_1/2 with temperature and number of carbon atoms will apply to other formulations of the same type (those in which the rate of evaporation is first order). The values of t_1/2 at 20° mainly agreed very well with those reported previously at room temperature However, previously reported values for pentadecyl and hexadecyl acetate were revised. Half-lives depend on the vapor pressure of a compound in the formulation substrate, but not on the vapor pressure of the pure compound

Field screening tests of 21 saturated and monounsaturated straight chain C₁₂ and C₁₄ alcs. and their acetates as well as some binary mixtures in dosages of 1 and 0.2 mg/dispenser were carried out in Lithuanian in 1993 and 1994. New sex attractants were determined for males of five moth species of the family Gracillariidae (E10-12:OH for Phyllonorycter sorbi, E10-12Ac for Ph. cydoniella and Ph. oxyacanthae, Z10-12:OAc for Ph. junoniella, and a mixture of Z10-14:OAc with E9-14:OAc in a 1:10 for Ph. sylvella), for four species of the family Tortricidae (E10-14:OAc for Endothenia ericetana, Z10-14:OAc in a 10:1 mixture with E11-14:OAc for Eudemis porphyrana, E11-14:OAc in a 10:1 mixture with E11-14:OH for Dichrorampha petiverella and Cochylis dubitana), for two species of Gelechiidae (Z9-14:OAc in a mixture with either Z10-14:OAc in a ratio 1:1, E9-14:OAc in a ratio 1:10 or E10-14:OAc in a ratio 10:1 for Bryotropha galbanella, Z10-14:OAc and E9-14:OAc in a ratio 10:1 for B. mundella), as well as for one species of each of the families Yponomeutidae (Z7-14:OAc for Paraswammerdamia lutarea) and Oecophoridae (Z10-14:OAc and E9-14:OAc in a ratio 10:1 for Pseudatemelia josephinae). Preliminary composition of sex attractants was established for three moth species of the family Gracillariidae (Z10-14:OAc in a 1:10 mixture with E9-14:OAc for Phyllonorycter heegerella, Ph. coryli and Ph. dubitella) and for one species of the family Gelechiidae (Z9-14:OAc for Bryotropha terella). Inhibitors of the sex attractants were found for four leafminer species of the family Gracillariidae (Z7-, Z9- and Z10-12:OAc for Phyllonorycter sorbi, Z10-, E10-12:OH and E10-14:OH for Ph. mespilella, E10-12:OH for Ph. cydoniella, Z10-12:OH and E10-14:OH for Ph. oxyacanthae), for three species of Tortricidae (E9-, Z11- and E11-14:OAc for Endothenia ericetana, E11-14:OAc for Gypsonoma minutana, E10- and E11-14:OAc for Epagoge grotiana), and for one species from the family Pyralidae (Z10-, E10- and E11-14:OAc for Pyrausta aurata). Data from male behavior tests in tube olfactometers are presented for Phyllonorycter blancardella, Ph. sorbi, Ph. dubitella and Ph. strigulatella and active compounds revealed.
