“…Notable shifts in the relative abundance of rice stemborer species over time suggest that their assemblages are ultimately structured through interspecific competition. Large scale changes in agriculture (e.g., crop diversity and distribution, crop rotations, pesticide and fertilizer inputs, irrigation regimes, land clearing) [48,[213][214][215][216][217][218][219][220] and rice cropping practices (e.g., extent of rice production, production intensity, crop duration, synchronization of cropping) affect resource availability, setting the carrying capacity of the environment for stemborers and influencing total stemborer abundance and consequent damage [22,27,30,31,33,40,191,221,222]. Some of these changes apparently favor some species more than others (see Section 3.5).…”

This review describes global rice stemborer assemblages based on published species distributions, apparent host preferences, and reported shifts in assemblage composition in response to environmental factors. At least 56 moth (Lepidoptera: Crambidae, Pyralidae, Noctuidae) and fly (Diptera: Diopsidae, Chloropidae) species have been associated with rice; however, only 21 species are of potential, large-scale economic importance with a further 2 species of localized concern; most of the remaining species’ associations with rice are based on dubious records without economic impacts on rice production. A list of stemborer–host associations indicates that rice stemborers are largely oligophagous on grasses (Poaceae), but a few species are polyphagous (also attacking Cyperaceae, Typhaceae, and some Eudicotyledon plants). Total stemborer abundance is determined by rice cropping patterns and management. Assemblage species richness is determined by geographical location, surrounding habitat (particularly as regards secondary and occasional species), and season. Evidence suggests that stemborer assemblage structure is largely determined through conditional interspecific competition. Regional assemblages typically include a single dominant lepidopteran species (primary species) that is largely restricted to rice and for which the climate is optimal; one or more secondary species that vary based on the age of rice attacked, rice anatomy, and the proximity to other habitats (including other crops); and occasional species that probably spill over from adjacent grasslands. The co-occurrence of lepidopteran with dipteran rice stemborers requires further research attention.
