각기 다른 화합물들을 성유인제로 이용하는 3종 과수해충인 복숭아순나방(Grapholita molesta), 복숭아심식나방(Carposina sasakii), 복숭아명나방(Conogethes punctiferalis)을 대상으로 단일 성페로몬 미끼 방출제에 2종 혹은 3종의 성페로몬 미끼를 섞어 복숭아원과 사과원에서 유인력을 검정하였다. 복숭아원에서 실시된 복숭아순나방 유인에서 복숭아심식나방이 섞인 혼합미끼 트랩에서 유인력이 감소하였으나, 혼합미끼를 이용한 복숭아원에서의 성충밀도 변이는 단일미끼 트랩과 높은 상관성 보였다. 사과원에서는 복숭아순나방에 대한 혼합미끼의 유인력 감소는 관찰되지 않았다. 복숭아심식나방 유인은 복숭아원과 사과원 모두에서 혼합미끼의 유인력은 단독미끼의 유인력과 유의한 차이가 없었고, 복숭아원에서 단독미끼와 혼합미끼 사이의 성충 밀도 변이 양상도 상관성이 높았다. 복숭아명나방 유인에서는 포획수가 너무 적어 평가가 불가능하였다. 이상의 결과에서 복숭아순나방과 복숭아심식나방 혼합미끼는 예찰에 이용할 수 있을 것으로 추정되었다.

This study attempts to investigate the impact of entrepreneurial orientation on positive psychological and behavior intention such as psychological ownership, work engagement, organizational citizenship behavior, sales efforts, adaptive selling behavior, performance for internal marketing based on job demands and resources model (JD-R model). The purpose of this study is to examine how the five-dimensional entrepreneurial orientation (innovativeness, proactiveness, risk taking, autonomy, aggressiveness) can affect salespeople’s positive motivation and to suggest how to manage and train salespeople effectively as internal customers. For this study, data were gathered from the respondents who are salespeople and analyzed by using structural equation model (SEM). According to the results of the study, entrepreneurial orientation affected salespeople’s positive psychological ownership and work engagement. In addition, we confirmed that psychological ownership affected to increase work engagement and organizational citizenship behavior, and work engagement was a positive precedence factor increasing organizational citizenship behavior, sales efforts and adaptive selling behavior. Lastly, we found that organizational citizenship behavior, sales efforts and adaptive selling behavior showed a positive impact on performance. Based on the study results, this research suggested academic and managerial implications to manage and train salespeople effectively in the business-to-business markets.

Ascotis selenaria, a major geometridae moth in citrus trees, annually damages the citrus leaves and fruits. The surface of young citrus fruit were usually fed by 1st larva of A. selenaria after landing or stepping onto the citrus fruits. To protect the larval damages of citrus fruits needs to predict the accurate occurrence time of the 1st larva for spraying. Because larval occurrences is dependent on the oviposition of adult female and the eggs were not found in/on citrus trees, oviposition model of A. selenaria linked with the egg development model will be helpful of protecting larval damages on citrus fruits. Adult longevity, survival and fecundity of A.selenaria was investigated at 13, 16, 20, 24, 28, 30, 32, and 35℃. The longevity decreased as the temperature increased and the female development rates (1/median longevity) were well described by a modified sigmoid model, which was used to calculate the adult physiological age. Description of the total fecundity was used by a non-linear model: The maximum fecundity of A. selenaria was estimated as 2490 eggs and peaked temperature was 19.7℃ according to the fecundity model. The cumulative age-specific oviposition rate and the age-specific survival rate was well described by 2 parameters Weibull function and a reverse logistic curve respectively. Total fecundity model, age-sepecific oviposition model, and age-specific survival model were incorporated into the oviposition model.

Ascotis selenaria, one of the major Geometridae moths, annually damages the citrus leaves and fruits. This study was focused to identify the sex pheromone components of A. selenaria in order to monitoring and control its population. Adult female and male were usually emerged at the time between 2 hour before and 2 hour afterlights-off in 16L:8D photoperiod. Mating, irrespective in female age, started at 2 hour after lights-off and peaked between 4 hour and 6 hour after lights-off. They copulated for 3 hour 47 min per pair. Gland extract of virgin female was analyzed with GC-MS and GC-EAD.Z,Z-6,9-3,4 epoxy nonadecadiene (Z,Z-6,9-3,4 epo- 19Hy) was identified as the candidate. Both of stereo isomer, Z,Z-6,9-3R,4S epo- 19Hy and Z,Z-6,9-3S,4R epo- 19Hy, showed a strong EAG response in male antennae. Further study like field attraction test should be needed to clarify the sex pheromone composition and in A. selenaria. Age and time were related with the amount of sex pheromone components biosynthesized in A. selenaria gland. 0 day old female had 112.7ng per gland at 5 hour after lights off and the amount was decreased as they aged. The sex pheromone biosynthesis started from lights-off and showed the increasing tendency during scotophase.
