The authors recorded a male individual forest of Byrnihat, located in Ri-bhoi distict state on November 23, 2017. current sighing revised distribution this species India being previously known Assam and West Bengal.

Abstract Aim Biogeographical inference and assessments of species' threat status trends depend on comprehensive information the current geographical distribution species. Even country‐level presences remain poorly known for many insect species consistent global overviews those are missing. Here we integrate from literature checklists, point occurrences, identify potential range gaps to provide ...

Polymerase chain reaction analysis was performed to determine whether mosquito predators in wetland habitats feed on Anopheles gambiae sensu lato (s.l.) larvae. Aquatic mosquito predators were collected from six wetlands near Lake Victoria in Mbita, Western Kenya. This study revealed that the whole positive rate of An. gambiae s.l. from 330 predators was 54.2%. The order of positive rate was th...

The insect growth regulator, Fenoxycarb, induced various morphogenetic aberrations in Notonecta unifasciata, Anax junius and Pantala hymenaea after treatment of late nymphal stages. Most affected nymphs died while molting from nymphs to adults. Fenoxycarb is also ovicidal to young eggs of N. unifasciata. The treatment rate of 0.034 kg AI/ha fenoxycarb induced some reduction in N. unifasciata po...

Probably the most common rock-imprint fossil-insect remain is an incomplete isolated wing. This pitfall has been traditionally addressed by manually reconstructing missing parts, which not ideal to comprehend long-term evolutionary trends in group, particular for morphological diversity (i.e., disparity) approaches. Herein we describe a new Triassic relative of dragon- and damselflies (Odonata)...
