The Leguminaceae, which is the third largest flowering plant family, has approximately 650 genera and 20,000 species and are distributed globally. There are various protein-rich accessible and edible legumes, such as soybean, cowpea, and others; nevertheless, their consumption rate is far higher than production, owing to ever-increasing demand. The growing global urge to switch from an animal-based protein diet to a vegetarian-based protein diet has also accelerated their demand. In this context, underutilized legumes offer significant potential for food security, nutritional requirements, and agricultural development. Many of the known legumes like Mucuna spp., Canavalia spp., Sesbania spp., Phaseolus spp., and others are reported to contain comparable amounts of protein, essential amino acids, polyunsatu...

Pesticides and other pest control methods are used during planting to eliminate pests that cause direct and indirect losses. In such situations, endophytic entomo-pathogenic fungi (EEPF) can act as a potential tools for biological control. They protect plants by boosting growth, nutrition, morpho-physiology and salt or iron tolerance. Antixenosis, antibiosis and plant tolerance change insect performance and preferences. EEPF-plant colonisation slows herbivore development, food consumption, oviposition and larval survival. EEPF changes plant physio-chemical properties like volatile emission profile and secondary metabolite production to regulate insect pest defences. EEPF produces chitinases, laccases, amylases, and cellulases for plant defence. Recent studies focused on EEPF species' significance, isolation, identification and field application. Realizing their full potential is difficult due to insufficient Frontiers in Plant Science frontiersin.org 01

In many countries, most of the food grains produced is stored for contingency and regular supply. These stored grains, in general, are directly or indirectly infested by insects, resulting in severe grain damages and storage losses, thus, causing a threat to food safety and security. Although a variety of insect management options, such as physical, mechanical, biological, and chemical methods, are available, fumigation has been practiced for decades in storage. However, opportunities for fumigation are narrowing after the phase-out of methyl bromide. Besides, safe food and health concerns paved the path for green chemistry and non-chemical management practices. This review includes the list of stored-grain insects and their detection methods. The different management strategies such as the modern storage structures (hermetic ...

The entomopathogenic fungus (EPF) (Alternaria alternata strain VLH1) infecting greenhouse whitefly on S. divinorum plants was isolated and morphologically and molecularly characterised using multilocus sequence typing. Results The fungus was found to be highly virulent against sucking pests; with LC50 values ranging from 1.7 × 104 to 2.5 × 106 spores per ml for the Mustard aphid (Lipaphis erysimi Kaltenbach) and soybean sucking bug (Chauliops choprai Sweet and Schaeffer), respectively. In the lepidopteran larvae treated with a concentration of 3 × 105 spores per ml, the fungus induced developmental abnormalities such as aberrant larval to pupal moulting, defective pupae, and deformed adults. Pathogenicity studies on the two beneficial insects (Coccinella septe...

In search of potential entomopathogenic nematodes (EPNs), soil samples were collected from, the rhizosphere of Apple orchard in Darima, Nainital, Uttarakhand, India north-western Himalaya in August 2019. The whole experimental activity carried out at ICAR-Vivekanada Parvatiya Krishi Anusandhan Sansthan, Almora during 2019–2021. In present study, Pristionchus pacificus was isolated using Corcyra bait trap, identified based on morphological and molecular approaches, studied its host range, evaluated the phylogenetic tree of P. pacificus and isolated and characterized the nematode associated bacteria. The reproduction potential and frequency of emergence of P. pacificus differs significantly among the tested hosts on Corcyra, Spodoptera and Holotrichia larvae. The molecular diagnostics of associated bacteria based on 16S gene displayed the highest homolo...

In the present study, more than 120 insect species were noted to visit onion flowers, out of which fifty-nine species were collected through in-situ sampling technique and identified up to species level. The Indian bee (Apis cerana indica) was the most abundant insect pollinator visiting onion flowers in the study location. The pollination behaviour and foraging activity of A. c. indica were assessed, and the pollen foragers were observed to be swift flyers visiting a significantly higher number of flowers per minute during the peak flowering period and spending less time per flower (3 seconds) to collect nectar from deep seated nectaries of the flowers. The seed yield enhancement assessed through entomophily and artificial pollination methods showed that the open pollinated flowers recorded the highest yield statistically, followed by A. c. indica and A. mellif...

The insect pests like wax moths and Dermestid beetles contribute immensely to the damage of bee colonies and reduction in honey yield in tropical regions of India. While, the bee colonies in temperate regions of Indian Himalayas, face an entirely different set of hitches that include predation of forager bees by three hornet species (Vespa mandarinia, Vespa velutina nigrithorax and Vespa tropica). The attacks on bee colonies by these hornet species compel the bees to desert the colony and swarm away to a new habitat thus, causing severe economic losses to bee keepers. Considering the severe setbacks enforced by hornets, a low-cost hornet trap was designed. The bait ingredients and their trapping efficiency against targeted hornet species are presented herewith. It was observed that green colored bottles attracted 34 hornets of three species in 10 days, while transparent bottles attracted only...

Although the economic value of domesticated bees is calculated through several scientificmethods, but the actual value of wild bees in terms of economy, ecology and biodiversity are rarelyestimated due to lack of distinct taxonomic keys. Considering the above backdrops, we decided tomolecularly characterize three species of Ceratina native to Indian Himalayas. Three species were reportedas C. sutepensis, C. smaragdula and C. similima based on phylogenetic analysis and comparison with the NCBIdatabase. The COI sequence of C. similima was submitted to the NCBI database for the first time. Nucleotidefrequency analysis showed that partial COI gene sequences were A+T biased (>75%), while the amino acidfrequency analysis showed higher frequency of leucine (16.01%) and serine (11.77%). Multiple sequencealignment of COI sequences of three species illustrated the total variation in...
