Pest Status, Bio-Ecology, and Area-Wide Management of Mirids in East Asia

Abstract

Mirids (Hemiptera: Heteroptera: Miridae) feed upon a wide variety of cultivated and wild plants and can be economically important crop pests. They have traditionally been perceived as innocuous herbivores in East Asia; however, population levels of various mirid species have dramatically increased over the past decades. High-profile pests such as Apolygus spp., Adelphocoris spp., and Lygus spp. are now widely distributed across the region, and their infestation pressure is associated with climate, agroecological conditions, and farming practices. This review outlines how an in-depth understanding of pest biology, a systems-level characterization of pest ecology, and a comprehensive evaluation of integrated pest management tactics have enabled sustainable management of mirids across crop boundaries and harvest cycles. This work underscores how more holistic, integrative research approaches can accelerate the implementation of area-wide management of generalist pests, effectively prevent pest population build-up and yield impact, and shrink the environmental footprint of agriculture. In addition to highlighting the merits of interdisciplinary systems approaches, we discuss prospects and challenges for the sustainable management of polyphagous mirid pests in landscape matrices. Expected final online publication date for the Annual Review of Entomology, Volume 69 is January 2024. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Geographical, seasonal, and growth-related dynamics of gut microbiota in a grapevine pest, Apolygus spinolae (Heteroptera: Miridae)

“…As shown here in A. spinolae, Proteobacteria consistently dominate the gut bacterial community in Miridae species, although the composition and dominant bacterial genus are remarkably diverse. While the feeding habits of A. spinolae are not thoroughly investigated, feeding habits of the Miridae are generally diverse from phytophagous to carnivorous through omnivorous, and change throughout their life cycle [12], which may be a factor causing their diverse gut community. Indeed, rearing experiments in Adelphocoris suturatis con rmed the diet-dependent effects on gut microbiota composition in this plant bug species [35].…”

“…In contrast to the well-studied stinkbug groups, the family Miridae of the infraorder Cimicomomorpha has long been neglected in terms of microbial symbiosis. Miridae includes more than 11,000 species worldwide [11], and they cause serious damage to agricultural crops [12]. Based on their anatomical features, members of the Miridae, or plant bugs, are not thought to be associated with any speci c gut symbionts.…”
