Temperature-Dependent Development and Emergence Pattern of <I>Hypothenemus hampei</I> (Coleoptera: Curculionidae: Scolytinae) From Coffee Berries

Abstract

The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), is the most important constrain for coffee production throughout the world. Knowledge on the emergence pattern of H. hampei females to infest new berries is crucial to effectively plan control measures. In this laboratory study, we assessed the development of immature stages and the emergence pattern of H. hampei females from the berries by exposing them to temperatures that are typical for high-altitude plantations (> or = 1,700 m above sea level [masl] ) or when coffee is grown under shade trees (20-22 degrees C), and optimum altitude plantations (1,200-1,600 masl) or nonshaded coffee (25-30 degrees C). Fecundity and emergence pattern of H. hampei females from coffee berries varied with temperature. Temperature played a crucial role determining the rate of H. hampei development and therefore the emergence of the females to start a new infestation cycle. The emergence and colonization phases of new colonizing females in coffee plantations with mean temperatures of 20, 25, or 30 degrees C would take place at different moments in the development of the coffee berries, and in some cases more than once. The implications of our findings for an improved, site-specific timing of control interventions against H. hampei are discussed.

Temperature-dependent development and survival of immature stages of the coffee berry borer Hypothenemus hampei (Coleoptera: Curculionidae)

“…Life history traits such as high reproductive rate and short life cycle (Jaramillo et al, 2009) may account for the success of H. hampei as a devastating pest of coffee. Another factor is that H. hampei spends most of its life cycle inside the coffee berry that makes damage difficult to detect at first sight, and chemical spraying usually inefficient (Brun et al, 1989).…”

Coffee Bean Heating Uniformity and Quality as Influenced by Radio Frequency Treatments for Postharvest Disinfestations

“…Since the beetle's life cycle is completed for several generations inside the bean, it is difficult to control this pest with pesticides or detect it with outside inspections. Although the beetle has been shown not to thrive in dry green bean or parchment (Trujillo, 1991;Jaramillo, 2010), observations have been made of live beetles in dry coffee beans after weeks of storage. Therefore, the Hawaii Department of Agriculture has established a quarantine regulation of the movement of coffee in any form to prevent introduction and spread of the pest within the state of Hawaii.…”

Parasitism of Hypothenemus hampei (Coleoptera: Scolytidae) in different farming systems and altitudes of Mount Elgon, Uganda

“…Hypothenemus hampei (Ferrari; Coleoptera: Curculionidae; Scolytidae) is an important pest causing devastation of Coffee plantations in the sub-Saharan agricultural regions, especially in East Africa (Jaramillo, 2012;Jaramillo, Chabi-Olaye, & Borgemeister, 2010). Population flare-ups are exacerbated by increasing trends in temperatures and solar exposures (Jonsson, Ijala, Ekbom, Kyamanywa, & Karungi, 2014).…”

“…Jonsson et al (2014) working in the area reported a 17 per cent increase in growth rate of H. hampei per degree increase in temperature. There is evidence of changing thermal temperature trends due to global changes and anthropogenic influences, which create micro conditions at specific locations (Jaramillo et al, 2010(Jaramillo et al, , 2011(Jaramillo et al, , 2013Jason et al, 2005;Seymoure, 2018).…”
