“…Larvae live confined within their host fruit until they complete their development, at which moment they normally exit the fruit to bury into the ground to metamorphose into pupae (Aluja et al., 2005). Larval development largely depends on the biochemical and nutritional characteristics of the host (Aluja & Mangan, 2008; Aluja et al., 2020; Balagawi et al., 2005; Oroño et al., 2019; Wu et al., 2011), which vary substantially among plant species and across different parts and different maturing and ripening stages of a single fruit (Birke et al., 2015; Fernandes‐da‐Silva & Zucoloto, 1993; Hafsi et al., 2016; Oroño et al., 2019). When hosts are scarce, females become habituated to host marking pheromones deposited on the fruit surface by previous ovipositing females, and a single fruit can be oviposited several times by the same or different females (Burrack et al., 2009; Lalonde & Mangel, 1994; Papaj & Aluja, 1993; Papaj et al., 1992).…”

Diet quality and the presence and abundance of conspecifics feeding on the same food resource are critical factors that affect functional traits of many animal species and influence ecological processes. We hypothesized that in insects whose larvae live in groups of varying sizes in ephemeral and nutritionally variable environments, extreme macronutrient content in the feeding substrate is a barrier for optimal performance that can be overcome by the collective feeding behaviour of large numbers of larvae. We experimentally examined how multiple immature and adult traits of the polyphagous tephritid fruit fly, Anastrepha ludens, vary as a function of the quality of its larval diet (protein + carbohydrate [P + C] content of 8.0%–12.6% w/w, and protein‐to‐carbohydrate [P/C] ratio of 1.8–0.11) across extreme levels of conspecific larval densities (60–600 larvae/60 g of diet). Overall, we found positive effects on survival of immature and adult stages, the duration of the larval stage, pupal weight and adult emergence of flies, as dietary P + C content increased, followed by negative effects when the diet had extremely high carbohydrate‐biased macronutrient content. Larval density had positive, negative and curvilinear effects depending on the macronutrient composition of the food, resulting in a range of fly responses through a continuous scale of macronutrient content and larval density combinations. Optimal performance of A. ludens, in terms of larval development time, body weight and survival to adulthood, was found when the diet consisted of low P + C content and high P/C ratios, and low larval densities. Our findings point to a diet‐mediated relationship between density and survival to the adult stage, suggesting that large numbers (up to a point) of larvae can balance negative effects of conspecific competition when food is characterised by high macronutrient content and low P/C ratios. We conclude that diet quality and conspecific density interact in complex ways to shape trait expression and performance in a frugivorous fly. Addressing this interaction is key to advance the understanding of the mechanisms behind changes in population dynamics in insect species living in groups confined in isolated and ephemeral resources.

“…There is a relationship between infestation and metabolic changes and/or accelerated ripening of the fruit (Keck, 1934;Oroño et al, 2019). Our results can assist in the search for an infestation interval pupae/kg that guarantees the recovery of immatures and partially prevents that the fruit have been submitted to high infestation index and suffer collapsing.…”

Oviposition performance of tephritid polyphagous Anastrepha fraterculus and Ceratitis capitata during three periods of exposure to fruit

et al. 2022

Our study evaluated the oviposition behaviour of Anastrepha fraterculus (Wiedemann, 1830) and Ceratitis capitata (Wiedemann, 1824) in five fruit species. Apples, guavas, mangoes, peaches and tangerines were exposed to infestation for 6, 12 and 24 hours. Anastrepha fraterculus and C. capitata showed different oviposition behaviour in apples and tangerines and similar oviposition behaviour in guavas, mangoes and peaches. There was a positive correlation between infestation time and pupae/kg, as well as between pupae/fruit and the survival rate of the immature (pupal viability). In this study, we present discussions about the oviposition behaviour of flies and the host infestation index. This index can reflect the reproductive capacity that each fruit species offers for each fly species. Here, we see an adult recovery rate greater than 89% in the highest infestation index observed in guava (185 A. fraterculus per unit fruit) and peach (220 C. capitata per unit fruit). Understanding the reproductive capacity of each host can help with risk analysis and the management of fruit flies.

“…Grouping larvae has been proposed as a strategy that improves their survival as it increases metabolic heat and colonization by bacteria and yeasts that can help breakdown toxic chemicals [19]. Recently, Oroño et al [96] reached a similar conclusion working with walnuts infested by A. fraterculus and C. capitata in Argentina. It is still unclear whether flies can sense the biochemical composition of host fruit, but our results suggest that flies might evaluate this by assessing peel quality.…”

With the aim of identifying key factors that determine oviposition decisions by Anastrepha obliqua for management purposes, we conducted a behavioral study under natural/semi-natural field conditions to identify where exactly in the fruit (upper, middle, or lower sections) females preferred to lay eggs in a highly susceptible mango cultivar (“Criollo”), and whether sunlight incidence and fruit chemical compounds influenced oviposition site selection by this pestiferous fly. Females oviposited in shaded, upper fruit sections where pulp had higher total carbohydrate concentrations but similar total protein, lipid, and polyphenol concentrations than non-oviposited sections. Peel had higher overall nutrient and mangiferin/quercetin-3-D-galactoside (polyphenols) concentrations. An untargeted metabolomic analysis of oviposited and non-oviposited fruit sections identified abscisic acid (ABA) and dihydrophaseic acid glucoside, a by-product of ABA catabolism, as potential chemical markers that could play a role in fruit acceptance behaviors by female flies. We conclude that females preferentially oviposit in fruit sections with optimal chemical and environmental conditions for larval development: more carbohydrates and antioxidants such as mangiferin and ferulic acid and lesser sunlight exposure to avoid lethal egg/larval desiccation/overheating. We make specific recommendations for A. obliqua management based on female host selection behavior, a tree pruning scheme exposing fruit to direct sunlight, application of a host marking pheromone, and the use of egg sinks in the orchard.
