In this study, a survey focusing on the status of clothing interest, inconveniences resulting from clothing, preferred design items, etc. was conducted on 364 elderly women to suggest aesthetically and functionally appropriate indoor wear design for at home elderly women aged 60 years or older. The survey results showed that in general, the respondents’ interest in clothing was high, and more respondents in their 70s or older had difficulty in the action of opening and closing. With respect to considerations when purchasing clothes, color was considered more important than design as respondent’s age increased, and size was regarded as the most important factor especially among those in their 80s. The preferred top styles were T-shirts and blouses among those in their 60s and 70s, and T-shirts and shirts among those in their 80s. The preferred sleeve lengths were “below the elbow” and “above the wrist” in all age groups. The preferred sleeve hem type was “tightening” in all age groups. The most preferred bottom styles were “straight-leg pants” and “elastic waistband.” This study suggests the design items of indoor wear, including top, bottom, and overgarment for warmth, appropriate for elderly women at home based on the survey results. The study results are expected to serve as basic data necessary for the revitalization of the clothing industry for elderly women.

Ooencyrtus nezarae lshii (Hymenoptera: Encyrtidae) is a major egg parasitoid of Riptortus pedestris (F.) (Hemiptera: Alydidae). One of the components of the aggregation pheromone of R. pedestris, (E)-2-hexenyl (Z)-3-hexenoate (E2HZ3H), is known to attract O. nezarae female. Response of O. nezarae females to E2HZ3H and its isomers was studied using electro-antennogram (EAG) and field tests. O. nezarae females showed higher antennal response to E2HZ3H and Z2HE3H isomers than E2HE3H and Z2HZ3H. In field tests, O. nezarae females were attracted to E2HZ3H traps, but not to Z2E3 traps. Interestingly, the blend of E2HZ3H and Z2HE3H showed significant antagonistic activities to the attraction of O. nezarae females in the field. We conclude from this study that Z2HE3H is a potent antagonist to the behavioral response of O. nezarae.
