Abstract
Cotton production in West Africa is
significantly constrained by insect pests, among which the leafhopper Amrasca
biguttula has recently emerged as a major threat in Côte d’Ivoire. This
study aimed to evaluate the impact of A. biguttula infestations and the
effectiveness of insecticide treatments on the growth and yield of cotton (Gossypium
hirsutum). A field experiment was conducted at the experimental farm of
Peleforo Gon Coulibaly University using a randomized complete block design with
three treatments: insecticide program A, insecticide program B, and untreated
control. Agronomic parameters including plant height, number of leaves,
flowers, and capsules were recorded weekly. The findings showed that
insecticide treatments significantly improved plant growth and productivity
compared to the untreated control. The highest values were recorded under
treatment A, with a maximum plant height of 45.62 cm, 49.32 leaves, and 6.33
capsules per plant. In contrast, untreated plants exhibited reduced growth and
yield due to severe pest attacks. The findings confirm the detrimental impact
of A. biguttula on cotton development and highlight the importance of
effective pest management strategies. Integrated pest management approaches are
recommended to optimize cotton productivity while minimizing environmental
risks.
