A record of Heterogynis penella (Hübner, [1819]) in the Cher, a Moth family new to the Centre region (Lepidoptera Zygaenoidea Heterogynidae). A male Heterogynis penella (Hb.) discovered in the Insect collection at the Muséum National d’Histoire Naturelle in Paris, taken in 1959 in the département of the Cher (18), proves to be a new species, indeed...

... We chose these two taxa because they represent two species with very different life histories: Plodia interpunctella is an important model organism in Lepidoptera whose larvae feed on various grains and stored food products and secrete large amounts of thin silken webbing at their feeding sites. They also use silk to create a cocoon during pupation [11,12]. Eubasilissa regina, on the other hand, is a member of the insect order Trichoptera, whose larvae secrete silk in aquatic environments to produce protective silk cases made of broader leaf pieces from deciduous trees, cut to size [13]. ...
Insect silk is a versatile biomaterial. Lepidoptera and Trichoptera display some of the most diverse uses of silk, with varying strength, adhesive qualities, and elastic properties. Silk fibroin genes are long (>20 Kbp), with many repetitive motifs that make them challenging to sequence. Most research thus far has focused on conserved N- and C-terminal regions of fibroin genes because a full comparison of repetitive regions across taxa has not been possible. Using the PacBio Sequel II system and SMRT sequencing, we generated high fidelity (HiFi) long-read genomic and transcriptomic sequences for the Indianmeal moth (Plodia interpunctella) and genomic sequences for the caddisfly Eubasilissa regina. Both genomes were highly contiguous (N50 = 9.7 Mbp/32.4 Mbp, L50 = 13/11) and complete (BUSCO complete = 99.3%/95.2%), with complete and contiguous recovery of silk heavy fibroin gene sequences. We show that HiFi long-read sequencing is helpful for understanding genes with long, repetitive regions.

The stored grain pests infest grains and other pantry items to fulfill their food and shelter requirements leading to both qualitative and quantitative losses. Due to favorable climatic conditions of Jammu, these stored grain insects register their presence throughout the year. These insects destroy and contaminate kitchen commodities with their fecal matter and undesirable odors and make them unpalatable, thus, posing a grave health hazard. Due to this reason, the post-harvest loss in India accounts for about 10% of the total grains and 9.5% of total pulses. The insects were collected randomly from places like super markets, grocery shops, ration depots, godowns, warehouses, etc. and were preserved in fumigated collection boxes using standard entomological procedures. From the study area, 16 insects under two orders namely Coleoptera (81.25%) and Lepidoptera (18.75%) were recorded on Pantry commodities within human dwellings in Jammu from 2017-2018. Of these, 9 insects have been recorded for the first time in the district, all of which belong to order Coleoptera. This is the first ever documentation of insect pests associated with stored grains from the Jammu district. However, this pilot study, which represents miniscule fraction of insect diversity in homes, requires a detailed and full scale investigations from the Jammu district, which is intended to be taken in further studies among these group of insects.
