“…Genieys, 1925;Narayanan et al, 1954), the body colour of adults of M. pulchricornis adults darkened when the cocoons were kept at low temperatures. We also revealed that the range in variation in colour differed for different body parts and among uniparental strains.…”

“…It is well-known that some parasitoid wasps show a temperature dependent phenotypic variation in body colour (Genieys, 1925;Narayanan et al, 1954;Shu-Sheng & Carver, 1982;Quicke, 1997;Bernardo et al, 2007), which might indicate that the colour of the body could be important in thermoregulation. However, there are no studies that link temperature induced changes in body colour with the performance of parasitoid wasps.…”

Abstract. We investigated the variation in body colour and its thermoregulatory function in Meteorus pulchricornis (Wesmael) (Hymenoptera: Braconidae), a parasitoid wasp of Spodoptera and other free-living lepidopteran larvae. We show that the body colour of adult wasps darkens when cocoons are kept at low temperatures. The range in the variation in colour, however, differs for different parts of the body and among uniparental (thelytokous) strains. This melanism enables these wasps to attain a body temperature in sunshine up to 2°C. Moreover, this small gain in body temperature can markedly increase the flight activity of wasps at low ambient temperatures. We conclude that the variation in body colour that resulted from rearing the cocoons at different temperatures enable the wasps to adapt to changing thermal environments. The ecological significance of the difference in the degree of melanism of the different strains is discussed.

“…Bracon brevicornis (Wesmael) is a gregarious ectoparasitoid of various Lepidoptera larvae, including many important pests, and is considered a cosmopolitan species [1,2]. In the past, B. brevicornis has been classified under the genus Habrobracon [3], Microbracon [4], or classified as one species with Habrobracon/Bracon hebetor [5]; however, recent research shows that B. brevicornis and B. hebetor are genetically two distinct species [6]. In the field, B. brevicornis has shown potential as a biological control agent against important pest species in stored corn stalks, such as Ostrinia nubilalis and Sesamia cretica [7], or against the coconut moth, Opisinia arenosella [2].…”

Bracon brevicornis is an ectoparasitoid of a wide range of larval-stage Lepidopterans, including several pests of important crops, such as the corn borer, Ostrinia nubilalis. It is also one of the earliest documented cases of complementary sex determination in Hymenoptera. Here, we present the linked-read-based genome of B. brevicornis, complete with an ab initio-derived annotation and protein comparisons with fellow braconids, Fopius arisanus and Diachasma alloeum. We demonstrate the potential of linked-read assemblies in exploring regions of heterozygosity and search for structural and homology-derived evidence of the complementary sex determiner gene (csd).
