is an ectoparasitoid of a wide range of larval-stage Lepidopterans, including several pests of important crops, such as the corn borer, . It is also one of the earliest documented cases of complementary sex determination in Hymenoptera. Here, we present the linked-read-based genome of , complete with an ab initio-derived annotation and protein comparisons with fellow braconids, and .

Biological control is widely successful at controlling pests, but effective biocontrol agents are now more difficult to import from countries of origin due to more restrictive international trade laws (the Nagoya Protocol). Coupled with increasing demand, the efficacy of existing and new biocontrol agents needs to be improved with genetic and genomic approaches. Although they have been underutilised in the past, application of genetic and genomic techniques is becoming more feasible from both technological and economic perspectives.

Coral reefs in the wider Caribbean declined in hard coral cover by ~80% since the 1970s, but spatiotemporal analyses for sub-regions are lacking. Here, we explored benthic change patterns in the Mexican Caribbean reefs through meta-analysis between 1978 and 2016 including 125 coral reef sites. Findings revealed that hard coral cover decreased from ~26% in the 1970s to 16% in 2016, whereas macroalgae cover increased to ~30% in 2016.

In variable environments, sampling information on habitat quality is essential for making adaptive foraging decisions. In insect parasitoids, females foraging for hosts have repeatedly been shown to employ behavioral strategies that are in line with predictions from optimal foraging models. Yet, which cues exactly are employed to sample information on habitat quality has rarely been investigated.

Because the quality of mating partners varies, females of several taxa have evolved the ability to discriminate against low-quality mates. Although males in the Hymenoptera are usually haploid, diploid males may occur in species with complementary sex determination. Diploid males are almost always sterile in most of the species studied so far.

The ability to learn is key to behavioral adaptation to changing environments. Yet, learning rate and memory retention can vary greatly across or even within species. While interspecific differences have been attributed to ecological context or life history constraints, intraspecific variability in learning behavior is rarely studied and more often, ignored: inferences of the cognitive abilities of a species are most of the time made from experiments using individuals of a single population.

Introduction: Allelic incompatibility between individuals of the same species should select for mate choice based on the genetic make-up of both partners at loci that influence offspring fitness. As a consequence, mate choice may be an important driver of allelic diversity. A complementary sex determination (CSD) system is responsible for intraspecific allelic incompatibility in many species of ants, bees, and wasps.

Olfactory learning is generally involved in the host-finding process in parasitic wasps. But the reliability of odour cues for predicting future host-finding success depends on the rate at which host-substrate associations are subject to variation within and between parasitoid generations. Since learning comes at physiological costs, we can expect animals to learn in a way that optimizes costs and benefits.

Parasitic wasps are faced with the decision of where and for how long to search for hosts. Their leaving decisions depend on the rate at which new host-containing patches are encountered: parasitoids increase foraging efficiency by leaving earlier when patch encounter rates become higher. The mechanisms by which these often tiny insects can assess patch encounter rates have not been thoroughly investigated so far.

Drosophilids and their associated parasitoids live in environments that vary in resource availability and quality within and between generations. The use of information to adapt behavior to the current environment is a key feature under such circumstances and Drosophila parasitic wasps are excellent model systems to study learning and information use. They are among the few parasitoid model species that have been tested in a wide array of situations.
