Abstract
稻黑樁象(Scotinophara lurida Burm.)乃新竹地區稻作主要害蟲之一。成蟲、若蟲均棲息於稻莖基部、較少在稻莖上部取食。該蟲年發生3代，越冬之成蟲在4月底侵入稻田為害。6月中、9月初及10月底各代成蟲出現。至二期稻收割後成蟲飛入雜草叢越冬。第一期作之蟲口密度高於第二期作。室內飼育一世代平均約需45天。若蟲5齡。卵期與各齡若蟲期平均分別為5、5.5、9、8.5、7.5及10天。本文觀察其形態、生活習性及田間之發生消長。
These observations were made during 1977 in Hsin-chu. The morphology, habits and the population fluctuation of the bug were reported.
Black rice bug (Scotinophara lurida Burm., Pentatomidae) has been known as one of the major pest on rice in Hsin-chu area in Taiwan. Its nymphs and adults inhabited on the basal part of rice plants and rarely feeding on the upper parts.
There were three generations during a year. In late April, hibernated adults invaded paddy fields. Then, the first, second and third generations adults emerged in middle June, early September and late October, respectively. The adults of third generation flew to their hibernated sites after the 2nd rice crop harvested.
The population density of the bugs during the 1st crop was higher than that of the 2nd crop. Under the laboratory conditions, the duration from egg to the adult emerged was about 45 days in average. Nymphs have five instars. The duration of the egg and 1st to 5th instar nymphs averaged 5, 5.5, 9, 8.5, 7.5 and 10 days, respectively.
