The potency of coconut shell wood vinegar and essential oils as botanical insecticides to control Hypothenemus hampei (Coleoptera: Curculionidae)

Abstract

Hypothenemus hampei is the major pest on a coffee plantation invested coffee berry in the field then unwittingly carried to storage. The aim of this research was to evaluate the potential of coconut shell wood vinegar and essential oils to control H. hampei. The research conducted in the Pest and Disease Laboratory of IIBCRI and Pakuwon Experimental Field started from January until December 2018. The test of clove oil and citronella oil residue conducted at 0, 1, 2, 3, 4, and 5 days after treatment (DAT) at a concentration of 2%; 3%; 4%; 5%; control (aquadest) and α-cyhalothrin insecticides (2 ml/l), respectively. Each treatment used 15 adults of H. hampei replicated 3 times. Coconut shell wood vinegar formulated into 2 formulas. Each formula was applied with different essential oil concentrations as 6 treatments and replicated 4 times. Result showed that the botanical insecticide formula of coconut shell wood vinegar + 5% clove oil caused mortality of H. hampei until 80 - 95%, and coconut shell wood vinegar + 5% citronella oil caused mortality of H. hampei reached 73.34 - 88.33%. Overall, the best botanical insecticide formula is a combination of coconut shell wood vinegar + clove oil.

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).…”
