The present paper deals with the revised description of some lesser known silent-slender crickets of Euscyrtinae (Orthoptera: Gryllidae) from the tropical hilly tracts of India. Besides, we describe a new species, Euscyrtus tubus sp. nov., and report the occurrence of Euscyrtodes ogatai (Shiraki, 1930) from India.

Background: Chemosensory perception plays a vital role in insect survival and adaptability, driving essential behaviours such as navigation, mate identification, and food location. This sensory process is governed by diverse gene families, including odorant-binding proteins (OBPs), olfactory receptors (ORs), ionotropic receptors (IRs), chemosensory proteins (CSPs), gustatory receptors (GRs), and sensory neuron membrane proteins (SNMPs). The oriental mole cricket (Gryllotalpa orientalis Burmeister), an invasive pest with an underground, phyllophagous lifestyle, causes substantial crop damage.

Gryllus madagascarensis (Orthoptera: Gryllidae) is a cricket species that shows promise to mitigate food insecurity and malnutrition. But whether this species will accept low- to no-cost weeds and agro by-products as feed, and how these feeds affect its performance, remains unknown. This study assessed the acceptability of 66 weed species and agro by-products (derived from a single plant species) by adult G.

Social parasites employ diverse strategies to deceive and infiltrate their hosts in order to benefit from stable resources. Although escape behaviours are considered an important part of these multipronged strategies, little is known about the repertoire of potential escape behaviours and how they facilitate integration into the host colony. Here, we investigated the escape strategies of the parasitic ant cricket Myrmecophilus tetramorii Ichikawa (Orthoptera: Myrmecophilidae) toward its host and non-host ant workers.

Heat shock proteins (HSPs) are well known to prevent and repair protein damage caused by various abiotic stressors, but their role in low temperature and freezing stress is not well-characterized in insects compared to other thermal challenges such as heat stress. Ice formation in and around cells is hypothesized to cause protein damage, yet many species of insects can survive freezing, suggesting HSPs may be an important mechanism in freeze tolerance. Here, we studied HSP70 in a freeze-tolerant cricket Gryllus veletis to better understand the role of HSPs in this phenomenon.
