“…It may be that the Goniozus contest interactions we observed were too brief (typically <60 s of agonistic interactions, including just a few seconds of fully escalated fighting, Petersen and Hardy, 1996) for energetic constraints on RHP to become apparent. Experiments that force G. legneri females into more sustained interactions, or that use bethylid species in which contests appear to be of naturally longer durations (Batchelor et al, 2005), may prove useful to explore this possibility further.…”

Sustenance and Performance: Nutritional Reserves, Longevity, and Contest Outcomes of Fed and Starved Adult Parasitoid Wasps

et al. 2018

Dyadic contests for possession of resources occur across a wide range of animal taxa, with contest outcome often being heavily influenced by the energetic reserves of the competitors. The majority of studied parasitoid wasps lack de novo lipogenesis, with adult lipid reserves being limited to those acquired throughout larval development. Carbohydrate-and lipid-rich diets can increase adult parasitoid lifespan and fecundity by potentially acting as a maintenance energy store. However, the effects of such diets on fat reserve compositions and contest outcome have not been examined. This study assesses the effects of a carbohydrate rich diet (honey) on the longevity, metabolic state and contest performance of Goniozus legneri, a bethylid wasp. The longevity of honey-fed adults was typically more than twice that of starved wasps. Compared to similarly-aged starved wasps, honey feeding increased concentrations of common haemolymph sugars and amino acids in 3-day old and 7-day old wasps, and higher concentrations of stored lipid in 7-day old wasps. However, nutritional status did not affect the outcome of dyadic contests over host possession when both contestants were either 3 days or 7 days old. While contest outcome may be unaffected by diet, it remains possible that an enhancing effect of feeding on contest ability is matched by an effect of higher value being placed on winning by starved wasps.

“…Similarly, reports from Infante (1998) in Mexico suggest that P. nasuta is only able to maintain high populations in the field if there are multiple releases. Previous attempts to resolve this riddle focused on the potentially negative interactions between C. stephanoderis, P. nasuta and C. hyalinipennis Ashmead, the latter being indigenous to the new world (Pérez-Lachaud et al, 2002, 2004Batchelor et al, 2005Batchelor et al, , 2006. However, Batchelor et al (2006) has recently suggested that P. nasuta should be the most effective biological control agent of CBB due to its comparatively superior emergence rate and female offspring production.…”

a b s t r a c tSeveral parasitoids of African origin have been introduced to coffee producing areas of the Americas and Asia as biological control agents of the coffee berry borer (CBB) Hypothenemus hampei (Coleoptera: Curculionidae). These parasitoids have become established in the field but their effect on the CBB has been limited. A two-year field study in Western Kenya has found Prorops nasuta (Hymenoptera: Bethylidae) to be the predominant parasitoid emerging from CBB-infested coffee berries collected on coffee trees or from the ground. P. nasuta comprises more than 75% of the total natural enemies collected. The density of P. nasuta was 90% higher in the berries collected from the ground than from the trees. Its hyperparasitoid, Aphanogmus sp. (Hymenoptera: Ceraphronidae), also emerged from both type of berries. Across the two seasons, the average P. nasuta density per berry was 18-35 times higher than that of Aphanogmus sp. Throughout the two years sampled, significantly higher numbers of P. nasuta and Aphanogmus sp. occurred between February and March, which coincides with the beginning of the rainy season. Higher numbers of live CBB females were recorded in berries collected from the trees. Nevertheless, mortality of adult CBB was considerably higher from January to March and started to decrease from April onwards.The possibly negative effects of cultural control practices in Latin America which include the removal of berries fallen to the ground on biological control of CBB are discussed, and the use of screened collection devices for these berries which would permit the release of parasitoids but prevent escape of the pest is proposed.

“…Competition between individual parasitoids of two different species (dyadic contest) occurs in coffee berries when a betilid female enters a berry previously colonized by a female of another species (Batchelor et al, 2005). This behavior is more likely to occur when CBB infested berries are scarce.…”

a b s t r a c tParasitoids native to tropical Africa have been released in the Americas for the biological control of the coffee berry borer (CBB), but their establishment has been checkered. A tritrophic distributed maturation time model for the coffee plant -CBB -three parasitoids (Phymastichus coffea, Cephalonomia stephanoderis, Prorops nasuta) system was proposed by Gutierrez et al. (1998). Based on this pioneering work, and improved models for coffee and CBB (Rodríguez et al., 2011(Rodríguez et al., , 2013, we present an updated version of the parasitoid models. The new elements in this analysis include:1. New data on the biology and behavior of the parasitoids are added. 2. A fourth parasitoid (Cephalonomia hyalinipennis) is added to the system. 3. Interspecific competitive interactions among parasitoids (e.g., dyadic contests, intra-guild predation and hyperparasitism) and their effects on the control of CBB are explored.Because field data on the effectiveness of the parasitoids on CBB control is sparse, we assessed the efficacy of the parasitoids for control of CBB heuristically. The results are compared to prior analyses, and are related to field observations. Specifically, we found:1. Control of CBB by betilid parasitoids (Cephalonomia stephanoderis, Cephalonomia hyalinipennis and Prorops nasuta) is ineffective because of their low reproductive capacity relative to CBB, their host-feeding behavior, and phenological mismatches with CBB life stages. 2. Of the parasitoids, the eulophid P. coffea has the greatest potential to suppress CBB infestation levels, though the fungal pathogen B. bassiana and insecticides are reported to have detrimental effects on its establishment and dynamics.
