Abstract
The potato is one of the most widely consumed horticultural products in the world.
It has a large number of insect pests that limit its production.
The synthetic products used in the fight against these pests are dangerous for humans and the environment.
However, biological control by conservation is one of the alternatives identified for the control of pests.
This study aims at assessing the impact of parasitoids in the management of potato pests.
Six plots were sampled in Kayar, Keur A Ndoye and Santhie Ndong sites every ten days.
The harvested caterpillars were monitored in the laboratory until emergence.
The results show that the plots of Keur Abdou Ndoye and Santhie Ndong are more infested than those of Kayar.
Eight species of parasitoids were obtained.
The parasitism rate was higher in Kayar and lower in Santhie Ndong. Tachinaria and the M. laphygmarum species are the most efficient parasitoids.
Conservation biological control is a good alternative to chemical control in the integrated management of potato pests.
