Impact of larval high density on the performance of Anastrepha ludens: competition or feeding facilitation?
<p>A critical point in diet management is maximizing density as a strategy for reducing costs. Artificial diets elaborated with large particle sizes have increased volume, possess high porosity and aeration capacity, are more penetrable and facilitate the movement of larvae, and increase the bioavailability of nutrients. The present experiment consisted in demonstrating that the bulking agent facilitates feeding and could have more capacity to support a high density of larvae with a minimal effect of competition on the life-history traits of <em>Anastrepha ludens</em>. The results indicate that density affected larval and pupal weight, but not pupation at 24 h, adult emergence, and flier percentage, which remained unchanged. However, there was an increase in yield and bioconversion. Larvae in high density conditions aggregated to increase the effect of regurgitation of amylases and proteases as a strategy to metabolize the food prior to ingestion through enzymes secreted in the saliva, contributing thus to feeding facilitation and the uptake of ingested food, which decreased the negative impact of competition in high density conditions. High density leads to an increase in food consumption and a consequent increase in digestive enzyme activity, contributing to the bioavailability of macronutrients ─ proteins, carbohydrates, and lipids ─ in the diet.</p> <p>Identifying the properties of bulking agents and other ingredients and their interaction under high-density conditions is essential to develop novel artificial diets and improve the mass-rearing strategies for the SIT.</p> <p> </p>
Nuclear genetic diversity and structure of Anastrepha ludens wild populations evidenced by microsatellite markers
<p class="MsoNormal"><span>The Mexican fruit fly, <em>Anastrepha ludens </em>is an important pest that causes widespread damage to a number of fruit crops in Mexico. The Sterile Insect Technique (SIT) is commonly used for its control. However, the existence of natural barriers can give rise to a population structure in neutral loci and possibly behavioral or adaptive traits that interfere with SIT. For this reason, it is important to understand the genetic diversity and structure of<em> A. ludens </em>populations and to better understand the evolutionary ecology and population processes in view of possible expansions and possible host shifts due to climate change. We genotyped nine nuclear DNA (nDNA) microsatellite loci among fruit fly populations collected from five biogeographic areas within Mexico, Mexican Plateau, the Northeastern Coastal Plain, the Pacific Coast, the Gulf Coast of Mexico, the Soconusco and a laboratory strain. The nuclear genetic diversity was moderate (from <em>H</em>e = 0.34 to <em>H</em>e = 0.39) within the wild mexfly population. We found that populations were clustered in three genetic groups (<em>K</em>=3). The diversity and genetic structure of <em>A. ludens</em> are produced by environmental and geological conditions as well as local conditions like anthropogenic perturbation which would produce population expansion and the existence of possible predators that would affect the population density. Gene flow showed recent migration among populations. The laboratory strain showed less diversity than the wild samples. Large values of current and ancestral population size suggest high resistance to climatic changes, probably due to biological attributes, such as its polyphagous, multivoltine and high dispersal characteristics. In particular ecosystem fragmentation and perturbation as well as the existence of new plant hosts all of which would probably increase the abundance of flies.</span></p>

Improving the mating competitiveness of male Anastrepha ludens (Diptera: Tephritidae) fruit flies by adding two juvenile hormone analogues
<p>Improving the mating competitiveness and survival of sterile males are direct means to increasing the effectiveness of the Sterile Insect Technique (SIT). Some insecticide growth regulators, such as the juvenile hormone analogue (JHA) Methoprene, have been used to improve the mating competitiveness of male tephritid flies by reducing their sexual maturation period. However, a decrease in the period of sexual maturation induces a reduction in survival. Here, we compared the effects of methoprene and Pyriproxyfen (PPF), another JHA, in <em>Anastrepha</em> <em>ludens</em> males. Pyriproxyfen is an insect growth regulator that exhibits higher disruption on insects’ methamorphosis than methoprene or than natural JH. . Both compounds were administered at two doses (0.05 and 0.1%) via the male diet immediately after emergence. Our results show that both Pyriproxyfen and methoprene reduced male sexual maturation. However, PPF-treated males exhibited a shorter maturation period and obtained more matings at a given age than methoprene-treated males . No significant differences were observed between the two PPF doses tested (0.05 and 0.10 %). Male survival was equally accelerated by the two compounds. Our results demonstrate that PPF can be used as a tool to improve the mating performance of sterile males.</p>

FASTA file of sequences of identified proteins in Anastrepha ludens reproductive tissues
<p>Seminal fluid proteins (Sfps) modify female phenotypes and have wide-ranging evolutionary implications on fitness in many insects. However, in the Mexican fruit fly, <em>Anastrepha ludens</em>, a highly destructive agricultural pest, the functions of Sfps are still largely unknown. To gain insights into female phenotypes regulated by Sfps, we used nano liquid chromatography mass spectrometry to conduct a proteomic analysis of the soluble proteins from reproductive organs of <em>A. ludens</em>. The proteins predicted to be transferred from males to females during copulation were 100 proteins from the accessory glands, 69 from the testes, and 20 from the ejaculatory bulb, resulting in 141 unique proteins after accounting for redundancies from multiple tissues. These 141 included orthologs to <em>Drosophila melanogaster</em> proteins involved mainly in oogenesis, spermatogenesis, immune response, lifespan, and fecundity. In particular, we found one protein associated with female olfactory response to repellent stimuli (Scribble), and two related to memory formation (aPKC, Shibire). Together, these results raise the possibility that <em>A. ludens</em> Sfps could play a role in regulating female olfactory responses and memory formation and could be indicative of novel evolutionary functions in this important agricultural pest.</p>

Data from: Reasons for success: rapid evolution for desiccation resistance and life-history changes in the polyphagous fly Anastrepha ludens
Species that exhibit broad ranges of distribution may successfully navigate environmental changes by modifying some of their life history traits. Environmental humidity imposes a critical stress that organisms may overcome by increasing their resistance to desiccation. We used experimental evolution to investigate adaptation to desiccation in the tephritid Anastrepha ludens, a species with high fecundity, late maturation and long lifespan. We measured morphological, physiological, developmental as well as demographic changes involved in the adaptation to desiccation. Notwithstanding a low heritability (h2 = 0.237), desiccation resistance evolved extremely rapidly and few negative trade-offs were detected. Selected flies exhibited correlated increases in longevity, body size, the amount of body lipids and bulk water content, and in the duration of the pupal stage. Females further delayed sexual maturation, decreased daily fecundity but retained high lifetime reproductive potential. No differences in male mating competitiveness were found. Selected and control lines differed in longevity but not in total female fecundity, demonstrating that A. ludens flies have the capability for fast adaptation to desiccation without loosing their reproductive capability. Thus, it seems that a rapid evolutionary response to desiccation in this polyphagous insect works as a buffer for environmental variation and reduces the strength of selection on reproductive traits.
