Abstract

Groundnut (Arachis hypogaea L.) is a legume that is highly coveted by West African populations, particularly those in Senegal. However, it suffers enormous damage caused by a bruchidae beetle, Caryedon serratus. This lust rests on its richness in proteins, calories and the absence of major constraints for its production. Losses recorded can reach 83% for a period of 4 months of storage. To counter this damage, several authors have looked for alternative methods to the use of synthetic insecticides, often harmful to animal populations and the environment. In this logic, we tested the biological impact of a leaf-based formulation of plants indigenous to Senegal (Crateva religiosa) on the external forms of C. serratus. In this study, analysis of the biological parameters of strain C. serratus showed low adult mortality of C. serratus. On the other hand, the extract affects the viability of eggs and larvae and fertility is reduced. The effect of the C. religiosa plant also results in reduced fertility of surviving females and a sex ratio in favor of the males causing a risk of decreasing population growth. On the other hand, there is an extension of the total development time.
山楂林叶片对花生抗性品系的杀虫效果研究
花生(Arachis hypogaea L.)是一种深受西非人民,尤其是塞内加尔人民喜爱的豆类。然而,它却遭受着一种叫做锯叶金龟子(Caryedon serratus)的水鳖科甲虫的巨大破坏。这种欲望建立在其丰富的蛋白质、卡路里以及对其生产没有重大限制的基础上。在4个月的储存期内,记录的损失可达到83%。为了应对这种破坏,几位作者寻找了使用合成杀虫剂的替代方法,合成杀虫剂通常对动物种群和环境有害。根据这一逻辑,我们测试了塞内加尔本土植物(Crateva religiosa)的叶子配方对锯齿状C.serratus外部形态的生物学影响。在本研究中,对C.serratus菌株的生物学参数的分析表明,C.serratius的成体死亡率较低。另一方面,提取物会影响卵子和幼虫的生存能力,并降低生育能力。宗教C.religiosa植物的影响还导致幸存雌性的生育能力下降,性别比有利于雄性,从而导致种群增长下降的风险。另一方面,总开发时间有所延长。
