Abstract

Abstract
Background Chemical control is generally used against aphids. The harmful effects of the chemicals used in the
control on the environment and human health have contributed to the development of alternative control methods.
The main objective of this study was to determine chemical composition of Mentha longifolia L. essential oil obtained
from spontaneous plants in Algeria, investigate repellent and con-tact toxicity effect on Aphis craccivora Koch control,
and assess the impacts of essential oil on development, survival and reproduction of A. craccivora.
Results The essential oil showed a concentration dependent significant toxic and repellent effects. The highest effect
was recorded for 8 μl/ml concentration of essential oil. The repellent effect and mortality rate in 8 μl/ml concentration
were 84.37 and 80.66%, respectively. The values of LC50 and LC90 were 1.848 and 26.782 μl/ml, respectively. The effect
of essential oil on immature period, adult longevity, natal period, survival, and fecundity was statistically significant
(p < 0.05).
Conclusions The findings in this study showed that the essential oil of M. longifolia harvested in the Tamanrasset
region of Algeria has a toxic effect on A. craccivora, and can have a potential to be used as an insecticide to control A.
craccivora. The use of environmentally friendly bioinsecticide will enable effective management of A. craccivora.
