“…In West Africa, the subspecies Sesamia nonagrioides botanephaga Tams and Bowden is also more prevalent in maize and sugarcane [32,101,166]. Similarly, the introduced species C. partellus is a major pest of rice in some parts of Africa [38,48]; however, it is mainly a pest of maize and sorghum in its native range in Asia [196,197], although it occasionally damages Asian rice [118]. Figure 1 indicates the approximate distributions of the nine economically important rice stemborers in Africa, as well as the European and Central Asian distributions of invasive or naturalized C. suppressalis [198,199].…”

The Structure of Rice Stemborer Assemblages: A Review of Species’ Distributions, Host Ranges, and Interspecific Interactions

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.

“…Spacing between plants has a paramount influence on vigorous growth of crop with provision of suitable microclimate while it also affects the incidence of many insect pests. High planting density resulted in more seeds and pod damage by pod sucking bugs in pigeonpea while higher planting density is favored in rice with respect to lower larva density and the damage by stem borer (dead heart and white head) in rice (Dialoke et al, 2018;January et al, 2020).…”

Integrated Pest Management is a sustainable and holistic approach based on ecological, biological, physical and chemical tactics for controlling pests in the field that, in any way, minimizes risk towards the health and environment. IPM methods involve identifying and knowing the characters of possible pests, making efforts to prevent prevalence, judgment of severity of pest-disease infestation through scouting and monitoring techniques. This paper highlights some of the already practiced strategies and experiments with interpretation of results obtained in various field conditions suggesting wider implications of IPM for managing pests in our fields. The review collects and studies some of the basic and commonly adopted cultural practices like clean and healthy crop growth, trap crop plantation, crop rotation, crop combinations etc. Cost effectiveness, ease of execution, instantly observable results etc are some unattainable aspects affecting IPM adoptions yet farmers seem somewhat encouraged towards sustainable and healthy production in recent years. It is necessary to know about crop and pest biology, ecology, phenology and their links/interaction to successfully implement cultural practices.

“…The impact of nitrogen and potash levels on the incidence of the early shoot borer, Chilo infuscatellus Snellen, in sugarcane varieties was studied at the Regional Research Station CCSHAU Uchani farm in Karnal, and it was discovered that when nitrogen was applied, the maximum mean percent incidence (7.12, 11.19, and 6.48, respectively) of early shoot borer was recorded at 250 kg N/ha in April, May, and June 2015, and the minimum (5.68, According to Singh et al, the administration of potassium with an optimal quantity of nitrogenous fertiliser, as well as the selection of a suitable variety, served as preventive measures against shoot borer infestation (2019). The effects of plant spacing and nitrogenous fertiliser on the occurrences and density of spotted and African pink stem borers were studied in a field experiment by January et al (2020). The treatments comprised four amounts of urea fertiliser (0, 40, 80, and 160 kg N ha-1) and four levels of spacing (10cm10cm, 15cm15cm, 20cm20cm, and 25cm25cm).…”

Sorghum [Sorghum bicolor (L.) Moench] is a vital essential nutriment crop in the biosphere and fifth most significant cereal crop afterward wheat, rice, maize and barley. NPK are elementary nutrients for plant development, which play a major role in uptake and energy creation in plants and suggestively improve the grain harvest. Sorghum is grown in a variety of agro-ecosystems, with varied biotic and abiotic variables influencing grain output. Arthropods are a serious difficulty for increasing sorghum yield among the biotic components. A variety of variables contribute to insect pest issues in the field, including alteration of the environment to make it more conducive to insect growth, reproduction, and development, as well as conventional cultural practises. Choosing pest-resistant cultivars that are well matched to local growing circumstances is the first step in integrated insect control in sorghum. This strategy is usually employed in conjunction with crop rotation, optimal planting date, trap cropping, cultivation of allelopathy or non-host crops, crop residue eradication, and field cleaning. Extant review has been made to cite the relevant literature on Impact of quantities of Nitrogen use on infestation of Sorghum insect pest.
