Efectividad De La Azadirachtina en La Inhibición De La Embriogénesis De Aegorhinus Superciliosus (Guérin) (Coleoptera: Curculionidae)

Abstract: La frambuesa es una fruta de exportación, cuyo cultivo en el sur de Chile es afectado seriamente por el curculiónido Aegorhinus superciliosus (Guérin) o cabrito del frambueso (CF), insecto nativo de Chile. La biología del CF es poco conocida y también su control. Se ha intentado reducir al adulto con insecticidas convencionales; sin embargo, en la práctica se dificulta su uso por coincidir la presencia del insecto adulto con periodos de floración y cosecha de fruta. Recientemente se están incorporando hongos e… Show more

“…In the case of the lupin infusion, the decreasing frequency of hatching could have occurred because the extract affected some stage of reproduction, which is consistent with the suggestion of Aguilera et al (2009), who concluded that azadirachtin has an effect that alters the laying and embryogenesis of A. superciliosus. Therefore, fecundity and fertility may be affected by secondary compounds from the plants studied that exert an insectistatic effect (Rodríguez et al, 2003).…”

“…The larvae bore into the lateral roots with their powerful jaws, finally boring into the primary roots to build chambers to pupate, which may cause the death of the hosts. After pupal eclosion, the emerged adults cause damage to leaves, buds and fruits [3,4,5].…”

“…The large morphological variability found in A. superciliosus in its natural distribution has allowed us to consider these as subspecies (Aguilera and Rebolledo 2001). However, it is now estimated that the morphological differences are associated with the color and distribution of the exoskeleton scales (Elgueta 1993).…”
