저장중(貯藏中)의 두류(豆類)에 대(對)한 팥바구미의 산란(産卵).식이(食餌) 및 우화(羽化)에 미치는 온도(溫度)의 영향(影響)과 식이선호적(食餌選好的)인 기주(寄主)와 비선호적(非選好的)인 기주간(寄主間)의 산란(産卵).부화(孵化) 및 우화(羽化), 피해종자(被害種子)의 발아율(發芽率)을 조사(調査)한 바 다음과 같은 결과(結果)를 얻었다. 1. 팥바구미는 상온조건(常溫條件)에서 연(年) 4회(回) 발생(發生), 유충태(幼蟲態)로 종자내(種子內)에서 월동(越冬)하였다. 2. 팥바구미의 산란적온(産卵適溫)은 범위(範圍)였으며 기주별(寄主別) 산란선호성(産卵選好性)은 팥>녹두>콩>강낭콩>검은콩>완두 순(順)이었다. 3. 생육최적온도(生育最適溫度)인 에서 기주별(寄主別) 팥바구미의 평균(平均) 우화일수(羽化日數)를 보면 팥 29일(日), 녹두 31일(日), 콩 49일(日), 검은콩 46일(日), 완두 34일(日)이었다. 4. 기주별(寄主別) 팥바구미의 부화율(孵化率)은 팥>녹두>콩>완두>검은콩>강낭콩 순(順)이었고, 우화율(羽化率)은 팥>녹두>완두>검은콩>콩>강낭콩 순(順)으로 팥과 녹두는 부화율(孵化率) 및 우화율(羽化率)이 높았고 콩, 완두, 검은콩은 부화율(孵化率)은 높았으나 우화율(羽化率)이 낮았으며 강낭콩은 부화(孵化)는 되었으나 전혀 우화(羽化)가 되지 않았다. 5. 성충(成蟲)의 수명(壽命)은 에서 일(日) 에서 일(日), 에서 일(日), 에서 일(日)로 고온조건(高溫條件)에서 짧았고 저온(低溫)에서 길어졌다. 6. 식이비선호적(食餌非選好的) 기주(寄主)인 강낭콩의 종피(種皮) 및 배유(胚乳)에는 산란(産卵)은 되었으나 부화후(孵化後) 발육(發育)이 되지 않았고 자엽(子葉) 및 배부위(胚部位)는 산란(産卵)도 되지 않았다. 7. 산란립(産卵粒)과 피해립(被害粒)은 발아율(發芽率)이 낮았는데 특(特)히 피해립(被害粒) 팥은 0%, 검은콩 5%, 완두는 7%의 낮은 발아율(發芽率)을 보였다.

This study was conducted to study the effects of temperature on the oviposition, feeding and emergence of the azuki bean weevil(ABW) (Callesobruchus chinensis L.) in the stored beans. And ovipositional preference, hatching and emergence on the preference and non-preference hosts were also investigated. ABW has four generations a year and overwinters as larva stage in the bean grains. Optimum oviposition temperature of the ABW ranges from . Oviposition preference in different hosts was in the order of azuki bean, mung bean, soy bean, kidney bean, black-soybean, pea. At , optimum development temperature emergence of period the ABW averaged 29 days on azuki bean, 31 days on mung bean, 49 days on soy bean, 46 days on black-soybean, 34 days on Pea. Percent hatch in different hosts was in the order of azuki bean, mung bean, soy bean, pea, black-soybean, kidney bean. But percent emergence was in the order of azuki bean, mung bean, pea, black-soybean, kidney bean. Especially, in azuki bean and mung bean, percentage of hatching and emergence was very high. And in soy bean and black-soybean, percentage of hatching was high but emergence was low. The kidney bean was hatching but not emergence at all. The longevity at the different temperatures appeared to be days at days at , days at days at . Kidney bean of feeding non-preference host oviposited at Seed coat and Endosperm, but no larva developed. And cotyledon and embryo parts were not oviposited at all. The percentage of germination of egg laid bean grain and damaged bean grains was low. Especially, the percentage of germination of damaged bean grains was 0% on azuki bean, 5% on black-soy bean, 7% on Pea.
