Efeito tóxico de flores de Heliotropium Indicum L. Sobre abelhas operárias africanizadas.

Abstract

Heliotropium indicum L. (Boraginaceae) is a subshrub that reaches up to 70 cm high, is widely distributed geographically. This species is known as sicklepod in the north and northeast. Given the biological potential of this species This study aims to identify a possible toxic effect of the honeybee Após melliferas Africanized under controlled conditions. For this. the flowers of the plant after being oven dried was weighed into three different fractions, namely (0.25%, 0.50% and 1 .0%) and added to the "candy" and water. For statistical analysis, we used the non-parametric test Log Rank test, comparing the survival curves. We measured the average mortality was assessed and the presence of the toxic effect of macerated Flowers sicklepod through time average mortality ranged from 1 1 to 15 days. The results showed that these flowers macerated in 1 .00% concentration provides early death of worker bees.
