Evolutionary loss of traits can result from negative selection on a specific phenotype, or if the trait is selectively neutral, because phenotype associated with has become redundant. Even essential may be lost, however, resulting phenotypic deficiencies compensated for by environment symbiotic partner. Here we demonstrate that an me-tabolic in parasitic wasps evolved through environmental compensation. We tested 24 species ability to synthesize lipids de novo and collected additional data...
Many animals avoid attack from predators through toxicity or the emission of repellent chemicals. Defensive mimicry has evolved in many species to deceive shared predators, for instance colouration and other morphological adaptations, but hardly ever seems involve multi-trait similarities. Here we report on a wingless parasitoid wasp that exhibits full spectrum traits mimicing ants affording protection against ground-dwelling (wolf spiders). In body size, morphology movement Gelis agilis...
The diet of organisms generally provides a sufficient supply energy and building materials for healthy growth development, but should also contain essential nutrients. Species differ in their exogenous requirements, it is not clear why some species are able to synthesize nutrients, while others not. unsaturated fatty acid, linoleic acid (LA; 18:2n-6) plays an important role functions such as cell physiology, immunity, reproduction, nutrient diverse organisms. LA readily synthesized bacteria,...
Oxygen is essential for most animals and exposure to a complete lack of oxygen, i.e. anoxia, can result in irreparable damage cells that extend up the organismal level negatively affect performance. While it known brief anoxia may confer cross-tolerance other stressors, few data exist on biochemical consequences repeated intermittent bouts exposure. In nature, Caribbean fruit fly Anastrepha suspensa (Loew)(Diptera: Tephritidae) frequently exposed heavy tropical rainfall while pupating soil,...
Phenotypic regression of morphological, behavioral, or physiological traits can evolve when reduced trait expression has neutral beneficial effects on overall performance. Studies the evolution phenotypic degradation in animals have concentrated mostly evaluation resulting phenotypes, whereas much less research been dedicated to uncovering molecular mechanisms that underlie regression. The majority parasitoids (i.e., insects develop inside other arthropods), do not accumulate lipid reserves...
The ability to synthesize lipids is critical for an organism’s fitness; hence, metabolic pathways, underlying lipid synthesis, tend be highly conserved. Surprisingly, the majority of parasitoids deviate from this general model by lacking convert sugars and other carbohydrates into lipids. These insects spend first part their life feeding developing in or on arthropod host, during which they can carry over a substantial amount reserves. While many parasitoid species have been tested lipogenic...
Abstract Numerous cases of evolutionary trait loss and regain have been reported over the years. Here, we argue that such reverse evolution can also become apparent when expression is plastic in response to environment. We tested this idea for fat synthesis parasitic wasps. first show experimentally wasp Leptopilina heterotoma switches lipogenesis on a fat-poor environment, completely off fat-rich Plasticity suggests species did not synthesis, but it be switched some environmental settings....
Lipid synthesis can have a major effect on survival and reproduction, yet most insect parasitoids fail to synthesize lipids. For parasitic wasps in the genus Leptopilina, however, studies suggested that there is intraspecific variation ability for lipid synthesis. These were performed only few populations, large-scale investigation of both lipogenic population genetic structure now needed. Here, we first examined nine Leptopilina heterotoma populations collected 2013 found five synthesized...
1. The optimisation theory predicts that insect mothers should oviposit on resources which they attain the highest exclusive fitness. development of parasitoid wasps is dependent limited host are often not much larger than adult parasitoid. 2. In present study preference and in three congeneric species secondary hyperparasitoids attacking cocoons two primary parasitoids differ significantly size were compared. Gelis agilis ( F abricius) G . acarorum L .) wingless forage grassy habitats,...
In arthropods, larger individuals tend to have more fat reserves, but data for many taxa are still missing. For the vinegar fly Drosophila melanogaster, only few studies provided experimental linking body size content. This is rather surprising considering widespread use of D. melanogaster as a model system in biology. Here, we hypothesized that content positively correlated with size. To test this, manipulated developmental environment by decreasing food availability. We then measured pupal...
