亚洲小车蝗飞行能力及其与种群密度的关系
The flight ability of Oedaleus asiaticus and its relationship to population density
摘要
Abstract
The flying ability of Oedaleus asiaticus which is a dominant locust species and its relationship with population density were studied in laboratory. The results of 12-hour continuous suspension flying test showed that O. asiaticus had relatively strong high-density population flying ability-the farthest accumulated flight distance was up to 15 km, accumulated flight time was more than 2 h. Different day-old adult individuals show significant difference, which 4 day-old adults after eclosion exhibited weaker flying ability, while the 13 day-old ones possessed the strongest flying ability, 20 day-old showed a decreasing trend. Male and female individuals had no significant difference (P〈0.05). Low-density populations of adults did not have the long distance flying ability, each day-old adult accumulated flying distance and flying time were significantly shorter than those of same day-old high-density population individuals (P〈 0.01).关键词
