Abstract

The beetle Caryedon furcatus (Coleoptera: Chrysomelidae) attacks and destroys the seeds of Senegalia macrostachya (Fabales: Mimosaceae), thereby limiting their availability as food throughout the year. Very few studies have focused on the ability of this pest to develop on S. macrostachya seeds. The objective of this study was to determine some bio-demographic parameters of C. furcatus on the seeds of S. macrostachya. The results of this study showed that the peak of female oviposition occurs on the second day after emergence. The female laid during her lifetime, an average of 37 eggs of which an average of 35 hatched, while larval survival until imago was 87.14 %. The weight and size of emerged adults did not differ statistically by sex. However, the sex ratio was female-biased. The mean development time for C. furcatus to complete its development on the seeds of S. macrostachya was 50 days. With a population that doubles every 4.75 days, C. furcatus could cause significant damage to the seed stocks of S. macrostachya.

卷叶Caryedon furcatus（Anton&Delobel）（鞘翅目：金花科）的一些生物学参数，在千里光（Reichenb.ex DC.）种子上的发育Boatwr。（寓言：含羞草科），布基纳法索的一种可食用野生豆科植物

甲虫Caryedon furcatus(鞘翅目:金龟子科)攻击并破坏了Senegalia macrostachya (Fabales:含水蝇科)的种子，从而限制了它们全年作为食物的可用性。很少有研究集中在这种害虫在大stachya种子上发育的能力。摘要本研究的目的是确定长柄山葡萄种子上的一些生物统计学参数。本研究结果表明，雌虫的产卵高峰出现在羽化后的第二天。雌虫一生平均产蛋37枚，其中平均孵化35枚，成活率87.14%。成虫的体重和体型在性别上没有统计学差异。然而，性别比例偏向女性。在大淀粉种子上发育完成的平均发育时间为50 d。其种群数量每4.75天翻一番，可对大葡萄种子库造成严重破坏。

期刊介绍： African Entomology (ISSN 1021-3589 – print / 2224-8854 – online) replaced the old Journal of the Entomological Society of Southern Africa in 1993. A single volume consisting of two issues (March and September) is published annually. The journal is indexed in all major abstracting journals African Entomology is a peer reviewed scientific journal that publishes original research articles and short communications on all aspects of entomology, with an emphasis on the advancement of entomology on the African continent.
