Abstract The development of biological control methods for exotic invasive pest species has become more challenging during the last decade. Compared to indigenous natural enemies, from area origin are often efficient due their long coevolutionary history with pest. import these well‐adapted species, however, restricted under Nagoya Protocol on Access and Benefit Sharing, reducing number available biocontrol candidates. Finding new agents ways improve important traits (“biocontrol traits”) is therefore crucial importance. Here, we demonstrate potential a surprisingly under‐rated method improvement biocontrol: exploitation intraspecific variation in traits, example, by selective breeding. We propose four‐step approach investigate this method: investigation amount (a) inter‐ (b) (c) determination environmental genetic factors shaping variation, (d) breeding programs. illustrate case study parasitoids Drosophila suzukii , highly Europe North America. review all known D. find large among within ability kill fly. then consider which shape interaction between its explain variation.

Nutritional geometry and fitness consequences in Drosophila suzukii, the Spotted‐Wing Drosophila

Ecology and Evolution, Journal Year: 2018, Volume and Issue: 8(5), P. 2842 - 2851

Published: Feb. 11, 2018

Abstract Since its arrival to North America less than a decade ago, the invasive Spotted‐Wing Drosophila ( suzukii ) has inflicted substantial economic losses on soft fruit agriculture due ability oviposit into ripening fruits. More effective management approaches for this species are needed, but little is known about factors that influence behavioral choices made by D. when selecting hosts, or consequences their offspring experience developing in different environments. Using nutritional geometry methodology, we found ratio of proteins‐to‐carbohydrates (P:C) present media greatly influenced adult behavior and subsequent development. Whereas flies showed strong bias oviposition association behaviors toward carbohydrate‐rich foods, larval survival eclosion rate were strongly dependent protein availability. Here, explore preference–performance hypothesis (PPH), which females predicted medias provide greatest benefits, regard relevance management. Our results valuable insight ecology evolution may hopefully lead more strategies.

Olfactory Preference of Drosophila suzukii Shifts between Fruit and Fermentation Cues over the Season: Effects of Physiological Status

Insects, Journal Year: 2019, Volume and Issue: 10(7), P. 200 - 200

Published: July 6, 2019

Worldwide monitoring programs of the invasive fruit pest Drosophila suzukii Matsumura (Diptera: Drosophilidae), using fermentation baits like apple cider vinegar (ACV), revealed a counterintuitive period low trap catches during summer, followed by an autumn peak. In this study, we demonstrate that ACV baited traps indeed provide distorted image D. population dynamics as it is possible to capture higher numbers "low period" with synthetic lures. It was hypothesised preference populations for cues most pronounced autumn, winter and spring, while flies prefer fresh summer seasonal related changing physiology over season. To test hypothesis, between (ACV) host fruits (strawberries) effect (sex, morphology feeding, mating reproductive status) investigated both in olfactometer laboratory experiments year-round field experiment. demonstrated protein deprived females, virgin females full complement unfertilised eggs males show strong fully fed morph generally cues.

Abstract A better understanding of the factors affecting host plant use by spotted-wing drosophila (Drosophila suzukii) could aid in development efficient management tools and practices to control this pest. Here, proxies both preference (maternal oviposition behavior) performance (adult emergence) were evaluated for 12 different fruits form purees. The effect chemical composition on traits was then estimated. We synthesized literature interpret our findings light previous studies that measured larval D. suzukii. show fruit identity influences parts life cycle, including under choice no-choice conditions, emergence rate, time, number emerging adults. Blackcurrant always among most preferred we used, while grape tomato least fruits. Larvae performed cranberry, raspberry, strawberry, cherry than other tested. found compounds can explain part suzukii traits. In particular, conditions strongly influenced phosphorus content. general, consensus across is blackberry, strawberry are best hosts blackcurrant, rose hips poor hosts.

Abstract Larval Drosophila encounter and feed on a diverse microbial community within fruit. In particular, free-living yeast microbes provide source of dietary protein critical for development. However, successional changes to the fruit may alter host quality through impacts relative content or composition. For many species , fitness benefits from feeding vary between individual species, indicating differences in nutritional quality. To better understand these associations, we evaluated how five impacted preference development larval suzukii . Larvae exhibited strong attraction Hanseniaspora uvarum pairwise assays. larvae also performed most poorly diets containing H. mismatch performance that suggests are not primary factor driving behavior. Together, results demonstrate plays role D. ’s ecology have developed specific associations. Further inquiry, including systematic comparisons associations more broadly, will be necessary patterns resource use other frugivorous species.

Nutrition is the single most important factor for individual's growth and reproduction. Consequently, inability to reach nutritional optimum imposes severe consequences animal fitness. Yet, under natural conditions, organisms may face a mixture of stressors that can modulate effects asymmetry. For instance, stressful environments caused by intense interaction with conspecifics. Here, we subjected house cricket Acheta domesticus (i) either two types diet have proved affect performance (ii) simultaneously manipulated their social environment throughout complete life cycle.

Protein and carbohydrate are the two major macronutrients that exert profound influences over fitness in many organisms, including Drosophila melanogaster. Our understanding of how these shape components D. melanogaster has been greatly enhanced by use nutritional geometry, but most geometric analyses on this species have conducted using semi-synthetic diets not chemically well-defined. Here we combined geometry defined to compare patterns larval adult life-history traits expressed across 34 systematically varying protein:carbohydrate (P:C) ratio protein plus (P+C) concentration. The response surfaces constructed for all differed significantly from one another, with optima being identified at P:C 1:4 lifespan (P+C 120 g l−1), 1:2 egg-to-adult viability (120 1:1 female body mass eclosion (240 l−1) lifetime fecundity (360 2:1 developmental rate (60 8:1 egg production l−1).
