Hypothenemus hampei ferrari (coleoptera: curculionidae) answer to visual and olfative stimuli in field

Abstract

The coffee berry borer (CBB), Hypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae: Scolytinae) is one of the main pests of world coffee growing. For the purpose of monitoring the presence of this insect, colored traps and attractives have been developed. Then, the objective of this work was to determine the association between trap colors and ethanol: methanol proportions in the CBB catch, and also to determine the infestation in the coffee plantation by the H. hampei. Painted traps of red, green and colorful (red upper half + green lower half) and six volatile mixtures were used. The reference mixtures consisted of ethanol: methanol (E:M), in the proportions of 1:1 and 1:3, with addition of 0.002 and 0.004 kg of pure caffeine powder. The infestation in the coffee plantation was determined by the H. hampei number count into the fruits and the traps. The insects caught number showed significant interaction between the factors color and mixtures of volatile compounds (F 107:85 = 2.46; p < 0.05). The peaks of H. hampei infestation occurred in the stages of grain formation (January) and maturation (April). The red traps with attractive E:M 1:1 + Benzoic Acid had the most significant effects in the H. hampei catch.

Estimating the effective sampling area of an alcohol-baited trap for monitoring the coffee berry borer

“…Nevertheless, our estimated sampling area suggests the use of approximately six traps ha -1 for CBB monitoring, which is lower than the average of nearly 19 traps ha -1 (range 2 -59 traps ha -1 ) that has been reported elsewhere (Mathieu et al, 1999;Fernandes et al, 2011;Pereira et al, 2012;Aristizábal et al, 2015Aristizábal et al, , 2017Johnson et al, 2018;Souza et al, 2020;Manoukis, 2020, 2021). This is economically desirable, as it reduces costs with traps, attractants, and labor time for sampling this coffee pest.…”

“…Despite extensive research on the use of these traps for CBB monitoring, consensus remains elusive regarding trap spacing and catch data interpretation, limiting the precision of IPM strategies (Mathieu et al, 1997b;Mathieu et al, 1999;Fernandes et al, 2011;Messing, 2012;Pereira et al, 2012;Aristizábal et al, 2017;Johnson et al, 2018;Oliveira et al, 2018;Souza et al, 2020;Manoukis, 2020, 2021;Ruiz-Diaz and Rodrigues, 2021).…”

Increased capture efficiency of Scolytinae with modified semi-funnel trap model

“…isopropyl alcohol and methyl alcohol (Matos et al, 2019). Furthermore, the color of the traps affect the collection of Scolytinae, as the number of individuals of the coffee borer, Hypothenemus hampei Ferrari, 1867 (Coleoptera: Curculionidae: Scolytinae) was higher in traps made with a red PET bottle baited with a mixture of ethanol and methanol (1:1 ratio) + benzoic acid than in those with a combination of other volatile mixtures with parts of ethanol, methanol, benzaldehyde and benzoic acid painted in colors green and red + green (Souza et al, 2020). Hypothenemus hampei is firstly attracted by the secondary metabolites produced by coffee during the fruit formation and then by the color and shape of this fruit (Leiva-Espinoza et al, 2019).…”

“…Hypothenemus hampei is firstly attracted by the secondary metabolites produced by coffee during the fruit formation and then by the color and shape of this fruit (Leiva-Espinoza et al, 2019). Therefore, the red color of the traps is more attractive as it resembles that of the coffee fruit stage in development (Souza et al, 2020).…”

Populasi, Serangan, dan Sebaran Hama Hypothenemus hampei pada Kopi Arabika Gayo

“…Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae) atau hama penggerek buah kopi merupakan hama utama yang menyebabkan kerusakan fisik pada buah kopi di perkebunan kopi di seluruh dunia (Aristizábal et al 2016;Pulakkatu-thodi et al 2018;; Ruiz-Diaz dan Rodrigues 2021). Hama H. hampei menyerang buah kopi robusta (Coffea canephora) yang dominan tumbuh di dataran rendah dan buah kopi arabika (Coffea arabica) yang umumnya tumbuh di dataran tinggi (Assis de Souza et al 2020;Abate 2021). Kehadiran Hama H. hampei dapat mengakibatkan penurunan produksi lebih dari 50% karena banyaknya buah kopi yang berlubang (Purba et al 2015).…”
