Botanical insecticide formulation with neem oil and D-limonene for coffee borer control

Abstract

The objective of this work was to evaluate the insecticidal activity of a botanical formulation with neem (Azadirachta indica) oil and D-limonene for the control of Hypothenemus hampei, as well as to determine the fatty acid composition of neem oil. Ninety-five percent neem oil was extracted from cold-pressed A. indica seeds, and D-limonene, from citrus peel. Humic extract (organic carbon), potassium, calcium, magnesium, and sulfur were included as additives. The analysis of neem oil by gas chromatography coupled to mass spectrometry showed that linoleic acid (49.28%) is the main fatty acid in its composition. Field tests were carried out on 'Topázio MG 1190' coffee (Coffea arabica) trees, with four applications of the formulated compound every 20 days for a period of 64 days. For the evaluation of insecticidal activity, the botanical formulation was applied to filter paper or topically on the insect’s dorsal side, showing a mortality of 63.34 and 100% after 48 hours, respectively. In the field, insecticidal activity caused a 62.4% reduction in the incidence of the H. hampei population, when compared with the control. The evaluated botanical formulation is efficient in controlling H. hampei in coffee plants.

The efficacy of botanical pesticides in controlling coffee berry borer, Hypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae): A meta-analysis

“…From these 17 studies, 133 comparisons for mortality rate of CBB from 14 different plant families were represented. The plant families that have botanical pesticide potential included in this study were Anacardiaceae (Santos et al, 2013), Apocynaceae (Zorzetti et al, 2012), Arecaceae (Indriati & Samsudin, 2018;Indriati et al, 2021), Euphorbiaceae (Celestino et al, 2016), Fabaceae (Zorzetti et al, 2012), Hypercaceae (Soares et al, 2022), Lamiaceae (Mawussi et al, 2009;Mendesil et al, 2011;Santos et al, 2022), Meliaceae (Zorzetti et al, 2012), Moringaceae (Zorzetti et al, 2012), Myrtaceae (Reyes et al, 2019), Piperaceae (Santos et al, 2010;Santos et al, 2011;Soares et al, 2022), Poaceae (Soares et al, 2022), Rutaceae (Brito et al, 2021), and Urticaceae (Soares et al 2022).…”

Bio-Insecticidal Potential of Tangerine Peel Oil Against Greenhouse Whitefly: A Green Biopesticide Candidate

“…The tangerine peel, a by-product of the tangerine agro-industry, is an excellent example of the valorisation of agricultural waste [45,79,80]. Obtaining an essential oil from the peel through extraction with organic solvents and its subsequent removal by distillation provides a product of natural origin that has very low phytotoxicity in potatoes (Solanum tuberosum) (results not shown), which allows one to obtain from it a candidate for a botanical, natural, and environmentally friendly insecticide [35,81].…”

“…On the other hand, some natural substances present in fruits and plant tissues have evolved to become repellents for insects and other pests [19,20]. Such is the case with some terpenes, such as d-limonene [34][35][36][37][38]. This monoterpene has demonstrated its biocidal and insecticidal effects against various pests [35,36].…”

“…Such is the case with some terpenes, such as d-limonene [34][35][36][37][38]. This monoterpene has demonstrated its biocidal and insecticidal effects against various pests [35,36]. D-limonene is found in the peels of many citrus fruits [39].…”

Toxicity of orange and neem oils at each stage of development of the coffee leaf miner, Leucoptera coffeella (Lepidoptera: Lynetiidae), and their side effects on predator Chrysoperla externa (Neuroptera: Chrysopidae)

“…Furthermore, this essential oil is characterized by the prevalent presence of the D-limonene molecule, whose toxicity against insects has been studied for other species, such as the coffee berry borer Hypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae)(Brito et al 2021). Our results have showed that neem oil effectively prevents the development of this pest.…”
