Inventory of the entomofauna and chemical control against the pests of Lippia Multiflora (Verbenaceae) in the South of Ivory Coast

Lippia multiflora(Verbenaceae), commonly known as savannah tea, is a plant that is found spontaneously in the savanna zone. It has medicinal properties and is used as a pesticide. Studies carried out for its domestication in the forest area have shown that it is imperative to make an inventory of the insects encountered in this new growing area. It is also a question of distinguishing those which are harmful with a view to developing control strategies. Identification was performed on both the hypogastric pest observed during excavations at the feet of the plants, and the epigastric pests causing extensive damage to the stems and leaves. Then, each elementary plot was treated, at a constant dose, with an insecticide (cypermethrin) every 7, 14 and 18 days. A sub-plot that received no chemical treatment served as a control. To evaluate the impact of the product on pests, observations were made on each plant. Damaged leaves and dead plants were noted. The results showed a highly significant difference between treated subplots and the control. But, no significant difference was observed between the frequency of treatments. Similarly, chemical treatment had no effect on hypogastric pests. Coleoptera appeared to be the most formidable of all epigean insects. Finally, the success of the domestication of the plant in humid zone, requires a chemical treatment of the soil before transplanting. Damaged leaves and dead plants were noted. The results showed a highly significant difference between treated subplots and the control. But, no significant difference was observed between the frequency of treatments. Similarly, chemical treatment had no effect on hypogastric pests. Coleoptera appeared to be the most formidable of all epigean insects. Finally, the success of the domestication of the plant in humid zone, requires a chemical treatment of the soil before transplanting. Damaged leaves and dead plants were noted. The results showed a highly significant difference between treated subplots and the control. But, no significant difference was observed between the frequency of treatments. Similarly, chemical treatment had no effect on hypogastric pests. Coleoptera appeared to be the most formidable of all epigean insects. Finally, the success of the domestication of the plant in humid zone, requires a chemical treatment of the soil before transplanting. chemical treatment had no effect on hypogastric pests. Coleoptera appeared to be the most formidable of all epigean insects. Finally, the success of the domestication of the plant in humid zone, requires a chemical treatment of the soil before transplanting. chemical treatment had no effect on hypogastric pests. Coleoptera appeared to be the most formidable of all epigean insects. Finally, the success of the domestication of the plant in humid zone, requires a chemical treatment of the soil before transplanting.
