A Report of Basic Ecology and Distribution, Host Plants of Cantao ocellatus (Hemiptera: Scutelleridae) in Korea

In this study, the distribution of Cantao ocellatus in Korea occurred at Jindo, Tongyoung, Gwangju and Taean including Jejudo in 2012 and was coincidentally in accordance with the distribution of Mallotus japonicus as a host plant. The adult emerges in M. japonicus occur from late June to early July and can be observed until the end of October. The investigation of the female and male was measured, developmental characteristics, host plant and oviposition preference under the conditions of temperature $25^{\circ}C({\pm}2)$, humidity 65%(${\pm}2$), day length 16L:8D, by indoor breeding. For females and males respectively, average body lengths were 26.20 mm and 23.88 mm, body widths 11.35 mm and 10.57 mm, head widths 3.84 mm and 3.64 mm, probosics lengths 7.90 mm and 7.27 mm, antennal lengths 9.87 mm and 9.69 mm, anterior leg lengths 12.50 mm and 12.27 mm, intermediate leg lengths 14.61 mm and 13.12 mm, posterior leg lengths 16.90 mm and 16.53 mm, and fresh weights 0.46 g and 0.31 g. It was seen that two kinds of C. ocellatus had prickles at the end of the pronotum which had developed in the fifth instars. The female is distinguished from the male by the reproductive organ and the spotted pattern on the abdominal segment. The preference of drinks was fruit, leafstalk, midrib, and branch in Mallotus japonicus (Thunb.) Muell. Arg., Mallotus japonicus 'Variegatus', Ricinus communis L., Lonicera japonicus var. repens (Siebold) Rehder, Citrus sinensis (L.) Osbeck and Zelkova serrata (Thunb.) Makino.

방패광대노린재 국내 분포, 기주식물 및 기초 생태 보고

방패광대노린재는 2012년 제주도, 진도, 통영, 광주, 태안에서 분포가 확인되었다. 성충은 6월 하순에서 7월 초순경에 예덕나무에 출현하며 10월 말까지 관찰이 가능하다. 실내 사육은 온도 $25^{\circ}C({\pm}2)$, 습도 65%(${\pm}2$), 광주기 16L:8D의 조건에서 성충의 암 수 형태 측정, 발육특성, 기주 및 산란선호성을 조사하였다. 체장(female: 26.20 mm, male: 23.88 mm), 체폭(female: 11.35 mm, male: 10.57 mm ), 두폭(female: 3.84 mm, male: 3.64 mm), 주둥이(female: 7.90 mm, male: 7.27 mm). 더듬이(female: 9.87 mm, male: 9.69 mm), 앞다리(female: 12.50 mm, male: 12.27 mm), 가운뎃다리(female: 14.61 mm, male: 13.12 mm), 뒷다리(female: 16.90 mm, male: 16.53 mm), 생체중(female: 0.46 g, male: 0.31 g)으로 각각 조사되었다. 우리나라에는 앞가슴등판 끝에 가시가 있는 개체가 있고, 가시의 유무는 마지막 5령 탈피시 생겨난다. 암 수 구분은 생식기와 배마디의 점무늬로 구별된다. 기주선호성은 예덕나무, 무늬예덕나무, 피마자, 털인동, 감귤나무, 느티나무의 열매, 엽병, 주맥, 가지를 흡즙하였다.
