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

Abstract

Although the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae) is the most destructive insect pest of coffee worldwide, there is much to learn about its thermal biology. This study aimed to develop temperature-based models for H. hampei development and to provide the thermal requirements of immature stages in the laboratory. Using a new observation method, larval development and survival were monitored daily on fresh Arabica coffee seeds, under seven constant temperatures in the range 15–35°C, with 80 ± 5% RH and 12:12 L:D photoperiod. Linear and non-linear functions were fitted to the development data plotted against temperature, using Insect Life Cycle Modelling software (ILCYM). Temperature significantly affected the development time of all immature stages. Egg incubation period ranged 4.6–16.8 days, under temperature between 30 and 15°C. No development occurred at 35°C and the larval stage did not develop to pupa at 15°C. The minimum temperature threshold (Tmin) estimated from linear regression was 10.5, 13.0, 15.0 and 13.0°C, for egg, larva, pupa and the total development from egg to adult, respectively. The maximum temperature threshold (Tmax) estimated from the Sharpe and DeMichele function was 32°C for egg to adult development. The thermal constant (k) was estimated at 78.1, 188.7, 36.5 and 312.5 degree days, for egg, larva, pupa and for egg to adult, respectively. Our results will help understand and predict the pest population dynamics and distribution in coffee plantations as impacted by temperature, and as such, will contribute to a more efficient management of the pest.

Biology and fertility of Hypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae) at 16 °C under laboratory conditions

“…For the CBB, the lowest threshold temperatureis between 10 and 18 °C,as reported by many authors (Jaramillo et al, 2009, Ruiz-Cárdenas;Baker, 2010, Giraldo-Jaramillo;Garcia;. In the present study, all CBB stages completed their development at 16 °C.Some authors, such as Jaramillo et al (2009) and Azrag et al (2020) have reported that the CBB life cycle was not completed at 15 °C.…”

“…These values are lower than those obtained in other studies of the effect of temperature on the CBB life cycle over the range of 18 to 30 °C. In general, the higher the temperature, the shorter the life-cycle duration and the higher the survival and fertility (Jaramillo et al, 2009;Garcia;Parra,2018;Azrag et al, 2020).…”

“…The coffee berry borer Hypothenemus hampei (Coleoptera: Curculionidae) (CBB) is a serious insect pest in coffee plantations worldwide (Benavides et al, 2013;Vega;Infante;Johnson, 2015). Studies of the thermal requirements of CBB (Jaramillo et al, 2009;Garcia;Hamilton et al, 2019;Azrag et al, 2020) indicate a strong correlation between insect development and abiotic factors, especially temperature, where the development time is inverse to temperature in the range between 18 and 32 °C Garcia;. The CBB did not develop at 15 °C (Jaramillo et al, 2009).…”

Determination of temperature thresholds for the parasitoid Diachasmimorpha longicaudata (Hymenoptera: Braconidae), using life cycle simulation modeling: Implications for effective field releases in classical biological control of fruit flies

“…To the best of our knowledge, three studies have attempted to determine the effect of temperature on D. longicaudata albeit under various conditions of host species, host stage, and diet among others. Liu et al 2012 [45] conducted their investigations on third instar larvae of B. dorsalis but unfortunately in our experience, exposing larvae of this stage to gravid females of D. longicaudata results in encapsulation or [46] Although insects do not develop at a constant temperature in nature, temperature-dependent development models built from the experimental data provide biological information that can be used for understanding the distribution, seasonality, and population dynamics of the insect species [48,49]. For the natural enemies, knowledge of temperatures that favor or limit the development and population growth for the predator/parasitoid, as well as the areas where the natural enemy can establish are important in biological control programs.…”

Temperature‐dependent development models describing the effects of temperature on the development of Spodoptera eridania

“…Numerous studies have demonstrated the influence that temperature exerts on the development and survival of insects 7,14,39 . Yet, because the response of insects to temperature is species‐specific, studies about the effect of temperature on insect biology are still relevant, particularly for agricultural and forest pests due to their application in pest management and prediction of species distributions under current and projected climate conditions using mechanistic or hybrid models 8,40–42 . In this context, knowledge of the thermal thresholds of insect pests may help in understanding the risks of a given species spreading to regions outside its native range.…”
