The mechanisms of host shift in phytophagous insects are poorly understood. Among the many proposed processes involved, sexual selection via semiochemicals has recently been suggested. This hypothesizes that sexual communication using pheromones is modified as a result of development on a new host, and such plant-induced phenotypic divergence in mate recognition cues can lead to reproductive isolation between host lines. We tested this hypothesis on Acanthoscelides obtectus, an oligophagous bruchid of Phaseolus vulgaris beans worldwide, which also develops in acceptable non-hosts, such as chickpea (Cicer arietinum L.). Male sex pheromone blends of the bean, chickpea and chickpea/bean host lines during artificially induced host shifts showed different composition. Bean-reared females did not distinguish between blends, whereas chickpea and chickpea/bean females preferred the chickpea male pheromone. However, electrophysiological (EAG) responses to male odour of antennae of the three female host lines were similar, all preferring bean-reared males. Egg-laying choice tests revealed a uniform preference for bean seeds across female host lines, even after multiple generations, whereas larvae did not distinguish between bean and chickpea seeds. We conclude that the development of divergent chemical signalling systems during host shifts does not facilitate the evolution of host races in A. obtectus, because oviposition preferences remain unaffected.

“…Moreover, successful pheromonal studies under laboratory conditions were done in stored-grain moths (Ephestia spp., P. interpunctella, S. cerealella) and stored-grain beetles (L. serricorne, T. granarium, Tribolium spp., S. paniceum). Besides, detailed semiochemistry of bruchids was exhaustively compiled by Rodríguez (2018), hence, they are not discussed in this study. Garcia et al (2003) sprayed sesquiterpenes (costic-aldehyde, Tessaric acid, eremophilane) isolated from Tessaria absinthioides on larvae of Tenebrio molitor and found that topical application of these sesquiterpenes increased pupal duration and induced morphological deformities.…”

Modernization of the agricultural production system led to a significant increase in annual food production intended to meet the ever-growing consumer demand. 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 and low-pressure storages), modified or controlled storage atmosphere, application of ozone as fumigant, irradiation, and physical options are presented. Further, the details on sustainable biological options, such as semiochemicals, natural enemies, biopesticides, and entomopathogenic nematodes, are supplemented. The use of inert dusts as grain protectant and in combination with the biological entity is included. Studies on alternative fumigants', novel management options, such as molecular biology tools (RNAi and CRISPR) and nanotechnology in stored grain protection, are also highlighted. This review helps the reader to understand the overall factors affecting grain storage and the different options to manage the insects causing storage losses.

“…Semiochemicals (behaviour‐ and development‐modifying chemical signals) can be divided into two broad groups based on the taxonomic relation of the participants: pheromones are used for intraspecific communication (Karlson & Lüscher, 1959 ), whereas allelochemicals convey information in an interspecific context (Whittaker & Feeny, 1971 ). The semiochemistry of bruchids has been reviewed previously (Francke & Dettner, 2005 ; Rodríguez, 2018 ). The reviews highlight the widespread occurrence of female‐produced sex pheromones in the subfamily.…”

The dried bean beetle, Acanthoscelides obtectus, is an economically important pest of stored legumes worldwide. Tracking the human‐aided dispersion of its primary hosts, the Phaseolus vulgaris beans, it is now widespread in most bean‐growing areas of the tropics and subtropics. In temperate regions where it can only occasionally overwinter in the field, A. obtectus proliferates in granaries, having multiple generations a year. Despite its negative impact on food production, no sensitive detection or monitoring tools exist, and the reduction of local populations still relies primarily on inorganic insecticides as fumigating agents. However, in the quest to produce more nutritious food more sustainably and healthily, the development of environmentally benign crop protection methods is vital against A. obtectus. For this, knowledge of the biology and chemistry of both the host plant and its herbivore will underpin the development of, among others, chemical ecology‐based approaches to form an essential part of the toolkit of integrated bruchid management. We review the semiochemistry of the mate‐ and host‐finding behaviour of A. obtectus and provide new information about the effect of seed chemistry on the sensory and behavioural ecology of host acceptance and larval development.
