运用田间观察和室内外饲养相结合的方法,对稻田蜘蛛优势种黄褐新园蛛(Neoscona scylla)的生物生态学特性进行研究。结果表明:每年黄褐新园蛛发生3~4代,第4代不完整,以第2、3代历期最短,第4代(越冬代)历期最长;以成蛛、亚成蛛或幼蛛越冬,其分布图式为聚集分布;属结网型蜘蛛。雌蛛、雄蛛均可多次交配,雌蛛一生最多可产卵12次,卵囊含卵量26~185粒,平均82粒。幼蛛期40~120 d,成蛛期33~176 d。除第2代外,各世代性比均为雌多于雄。
The bio-ecological characteristics of Neoscona scylla, a dominant spider species in paddy field, were studied using a combination of field observations and indoor and outdoor feeding. The results showed that: each year 3 to 4 generations of young yellow garden spider occurred, the fourth generation is not complete, the second and third generation of the shortest period, the fourth generation (overwintering generation) the longest; Or young spider wintering, the distribution pattern for the aggregation distribution; is a net-shaped spider. Female spiders, male spiders can be repeatedly mated, female spiders can spawn up to 12 times life, egg oocysts containing 26 to 185, an average of 82. Juvenile spider 40 ~ 120 d, into the spider period of 33 ~ 176 d. In addition to the second generation, the sex ratio of all generations are more than male.
