| Abstract | |
Despite chemical control remaining the predominant strategy for pest management, the utilization of sustainable control tactics has been growing as a crucial approach to mitigate environmental impact and ensure safe food production, particularly within intensive coffee cultivation. The objective of this research was to investigate the efficacy of botanical insecticides based on orange oil and neem oil for managing Leucoptera coffeella (Lepidoptera: Lyonetiidae) infestations, while additionally assessing the side effects of these insecticides on predator Chrysoperla externa (Neuroptera: Chrysopidae), commonly found in coffee cultivation areas. To achieve this, we examined the impact of botanical insecticides on eggs, larvae, pupae, and adults of L. coffeella , as well as on eggs and larvae in the first, second, and third instars of C. externa . The results obtained from this research indicate that the utilization of botanical insecticides derived from orange oil and neem oil, when applied to eggs, resulted in reduction in the hatching rates of coffee leaf miner larvae (75.0 -97.6%). Furthermore, when applied to larvae of its predator, C. externa , these insecticides demonstrated compatibility with the survival of the natural enemy. Both neem oil and orange oil exhibited the ability to prevent larvae from hatching from L. coffeela eggs when applied to adults. In light of these findings, it is evident that botanical insecticides formulated from orange oil and neem oil could serve as viable alternatives for the sustainable management of the coffee leaf miner, a significant pest in coffee cultivation.
