Variation in Sex Pheromone Composition of a Few Selected Lepidopteran Species
Boo, Kyung-Saeng Korean Society of Applied Entomology 1998 Journal of Asia-Pacific Entomology Vol.1 No.1
Composition of insect sex pheromone is not always constant for any particular species. It may be different depending on the geographical area in the distribution of a species, as can be seen in the case of the European corn borer moth, Ostrinia nubilalis (Pyralidae). During the course of examining sex pheromone compositions of several lepidopteran species damaging agricultural and horticultural crops in South Korea, some subtle or apparent differences were noticed in sex pheromone compositions of Korean population belonging to those same species distributed in her neighboring countries. The oriental tobacco budworm moth, Helicoverpa assulta(Noctuidae), in Korea prefers the blend of 100 : 5 between(Z)-9-hexadecenal and (Z)-11-hexadecenal, while Thailand population responds best to 100 : 13 and Chinese population to wider blends from 100 : 2 to 100 : 20. Among lepidopteran insect pests on apples and apple tree leaves, the oriental fruit moth, Grapholita molesta(Tortricidae), showed almost no difference from one region to another. Korean population responded best to the blend of 100 : 5, with other populations to 100 : 6~100 : 9 between (Z)-8-dodecen-1-ol acetate and (E)-8-dodecen-1-ol acetate. Onthe other hand, the peach fruit moth, Carposina sasakii(C. niponensis) (Carposinidae), males were attracted best to a single component, (Z)-7-eicosen-11-one in the case of Korean population, in contrast to Japanese population which was shown to be preferentially attracted to the mixture of the (Z)-7-eicosen-11-one and (Z)-7-nonadecen-11-one at the ratio of 100 : 5. The yellow peach moth, Dichocrocis pundtiferalis(Pyralidae), seems to consist of two different populations in the northeastern Asia region, with one group resonding to the blend of 100 : 8~100 : 11 between (E)-10-hexadecenal and (Z)-10-hexadecenal and the other to tat of 100 : 43. The first group was found in Japan ad China and the second in Korea and also China. Korean population of the apple leaf miner, Phyllonorycter ringoniella(Gracillariidae), was best attracted to the blend of 100 : 150 between (Z)-10-tetradecen-1-ol acetate and (E, Z)-4, 10-tetradecen-1-ol acetate, while Japanese and Chinese popilations to the blends of 100 : 10~30 and 100 : 43~67, respectively. Furthermore, Korean Adoxophyes(Tortricidae) seemed to be a totally different species from Japanese Adoxophyes sp., or Adoxophyes orana fasciata, when viewed in terms of their pheromone composition.
Mating Effect on Sex Pheromone Production of the Oriental tobacco budworm, Helicoverpa assulta
Boo, Kyung-Saeng,Ahn, Seung-Joon,Choi, Man-Yeon Korean Society of Applied Entomology 2002 Journal of Asia-Pacific Entomology Vol.5 No.1
This study was undertaken to clarify the suppression phenomenon of sex pheromone production after mating and its relationship to the physiological mechanism in adult females of Helicoverpa assulta, and determine the mating factor from males causing depletion of sex pheromone production. Sex pheromone production of H. assulta females was mostly terminated in 3 hours after mating. Mated females maintained with a low titer of sex pheromone until 3 days when it started to increase again, which showed a ciaracteristic of species mating more than once. The mated female again produced pheromone upon injection of pheromone biosynthesis activating neuropeotude (PBAN) or extracts of brain-suboesophageal ganglion complexes (Br-Sg) of mated female, which were shown similar pheromonotropic activities as compared with virgin females. These results indicated that the mating did not inhibit the receptivity of pheromone gland itself and PBAU biosynthesis in suboesophageal ganglion of the mated females. And it seems to support that the depletion of sex pheromone production is responsible for blocking of PBAN release from head. To investigate the mating factor from adult males, when extracts of reprohuctive organs of male were injected into hemocoel of virgin females evoking depletion of sex pheromone production as shown in mated female. The results suggest that a chemical substance(s) from the male reproductive organs could be responsible for the loss of sex pheromone biosynthesis in H. assulta.

Attraction of Chryrsopa cognata (McLachlan) adults to two major aphid sex pheromone components, (-)-(1R,4aS,7S,7aR)-nepetalactol (NL) and (+) - (4aS,7S,7aR)-nepetalactone (NN) , was investigated in field experiments in Korea. C. cognata adults were much more highly attracted to NL than to NN. Even though NN also attracted significantly more C. cognata adults than did solvent control, there were no synergistic or additive effects on the trappings by NL. In a series of trapping experiments with blends of the two chemicals, C. cognata numbers trapped tended to increase with the content of NL, but never more than that by NL alone. As the amount of aphid sex pheromone components increased, more C. cognata were captured. However, the period of attraction for NL significantly decreased with time and after 50 days few C. cognata adults were attracted. C. cognata adults were mainly captured during the night and only a few were attracted in daytime during the late fall period. Even during the night, most of C. cognata were attracted from about 7:00 PM to 11:30 PM with apparently a longer period of activity in the summer than in the fall with an intermediate activity period in the spring. C. cognata adults caught in traps throughout the trap experiments were almost only males, in agreement with electroantenogram(EAG) results which showed that only male adults responded. The EAG response was stronger to NL than to NN. In addition to C. cognata, a few male adults of Chrysopa formosa (Brauer) and Chrysopa phyllochroma (Wesmael) were also captured in field pheromone traps.
배과수원에서 발생하는 차애모무늬잎말이나방(가칭, Adoxophyes sp.)에서의 성페로몬 합성 조절과 PBAN cDNA의 구조

The smaller tea tortrix, Adoxophyes sp. (Lepidoptera: Tortricidae) is a serious pest damaging leaves of pears and teas in Korea and other Asian countries. Adoxophyes in Asia including A. sp. have various characters in morphology, host preference, and sex pheromone composition. But the taxonomy, sexual isolation mechanism, and evolution of pheromone polymorphism in Adoxophyes are not clearly established. Though GC analysis, it was revealed that (Z)-9-tetradencenyl acetate (Z9-14Ac) and (Z)-11-tetradencenyl acetate (Z11-14Ac) are sex pheromone components of A. sp. Composition of pheromone components was 40 : 0 between z9-14Ac and Z11-14Ac in pheromone gland extract and female effluvia. Mating behavior and pheromone production in A. sp. Showed diel rhythm. A. sp. Mated and maximally produced the pheromone immediately after lights-on under a photoperiod of 16L/8D. Pheromone production was stimulated by injection of male of female head extracts, or Hez-PBAN. Therefore, it was proposed that pheromone production in A. sp. Is regulated by a neuropeptide, maybe PBAN, produced from the head. A 750 bp-long cDNA encoding PBAN of A. sp. Was fully characterized. PBAN cDNA contains a predicted open reading frame (ORF) of 576 nucleotides encoding and 192-amino acid long polypeptide. This polypeptide is predicted to be cleaved into 5 putative peptides including PBAN by endoproteolytic processing. PBAN of A. sp. Is a 31-aminoacid long neuropeptide and has 35-48% homology with PBANs from other moths. Other four putative peptides encoded in PBAN cDNA of A. sp. Are 24-amino acid, 7-amino acid, 20-amino acid, and 8-amino acid long. Through immunocytochemical studies, neuronal cells producing PBAN-like peptides were identified. Immunoreactive cells were located in the brain, suboesophageal ganglion (SG), and some ganglia in the ventral nerve cord (VNC). Immunoreactiv cells in the SG constitute three clusters and project neuritis to the corpora cardiaca. A couple of neuritis from the SG descended through the VNC and terminated in the terminal abdominal ganglion.
