Abundance and Incidence of Zucchini (Cucurbita pepo L) Flies in the Korhogo Department of Northern Côte d’Ivoire and Pest Control Methods Used by Farmers | Chapter 11 | Advances and Trends in Agricultural Sciences Vol. 1
To improve
the production of zucchini in Côte d'Ivoire and particularly in to Korhogo
Department, a study was carried out at the Peleforo Gon Coulibaly University
research site and at four farmers’ sites during dry and rainy seasons. On each
plot, the number of healthy and attacked fruits was evaluated, based on a
random sample of 100 fruits. The attacked fruits were transported to the
laboratory and incubated to determine the causative agents. The methods and
pesticides used to control insect pests by farmers were listed. During the
rainy season, 86.06% of the fruit was attacked by flies while 13.94% remained
healthy. In the dry season, for a total of 9,617 controlled fruits, 7,439
(77.35%) were healthy and 22.65% were attacked. Four insects species emerged
from infested fruit. They were Bactrocera cucurbitae, Dacus ciliatus, Dacus
bivittatus, belonging to the family of Tephritidae, and Scaeva pyrastri
belonging to Syrphidae. The method used by farmers to control pests was not
effective. In conclusion, flies represent the limiting factor of zucchini
production during the rainy season in to Korhogo Department. At the end of this
research, it emerges that the main zucchini pests in the Korhogo Department are
Bactrocera cucurbitae, Dacus ciliatus, and Dacus bivittatus of the family
Tephritidae. The species Scaeva pyrastri of the family of Syrphidae is not
responsible for the loss of fruit; it comes only secondarily after the attack
of Tephritidae. Pesticides used by growers in the control of pests are not
indicated. Because of the strong presence of flies in the rainy season on
zucchini and the damage they cause, the production of zucchini during this
season may not be profitable.
