“…Insect prey were then classified as crop pests and non-pests following the published literature on rice pests (Pathak, 1968;Rothschild, 1971;Barrion and Litsinger, 1994;Dale, 1994;Pathak and Khan, 1994;Chen et al, 2005;Singh and Singh, 2014). For example, crop pests include rice plant weevil, root weevil, rice borer, stem borer, grasshoppers, caterpillars, crickets, insect larvae, leaf hoppers, aphids, and mole crickets that are harmful to plants and may affect crop yield (Neupane, 2010).…”

“…Larval feeding on rice plants at the vegetative stage leads to yellowing and drying of the growing shoot, resulting in the formation of ÔÔdeadheartsÕÕ; while, larval feeding at the reproductive stage results in panicles with unfilled grains called ÔÔwhiteheadsÕÕ (Pathak, 1968). In addition, larval feeding can also cause reduced plant vigor, fewer tillers, unfilled grains and lodging of plants (Dale, 1994).…”

Interactions between the striped stem borer Chilo suppressalis (Walk.) (Lep., Pyralidae) larvae and rice plants in response to nitrogen fertilization Abstract A screenhouse experiment was conducted to examine the damage and compensation in rice plants when injured by the striped stem borer, Chilo suppressalis (Walker), larvae at tillering stage, as well as larval survival and development of the insect at different nitrogen (N) fertilization levels. Potted plants were fertilized at late seedling stage at the rates 0, 200, 400, 600 and 800 mgN/pot, respectively. More deadheads were caused as fertilization increased. Plants compensated well for injury at the fertilization concentrations of 200 and 400 mgN/pot by producing new tillers, but such compensation did not take place at 600 and 800 mgN/pot. Two weeks after infestation, the highest number of remaining healthy tillers was found in plants fertilized at 400 mgN/pot. Larval survival varied little among the treatments 200 to 800 mgN/pot. Larval weight attainment and/or developmental rate increased with increasing fertilization level from 200 to 600 mgN/pot, but both declined rapidly as fertilization reached 800 mgN/pot, indicating the great dependence of plant suitability on N fertilization levels. Conclusively, both the compensation response of rice plants and their suitability for C. suppressalis larvae could be significantly affected by N fertilization levels. 124M. X. Jiang and J. A.

“…So far, 175 species of insects have been identified on rice from seed sowing to crop harvest (Kamal, 1998). Among them, only 20 species are considered as pest (Pathak, 1968) and 20-30 species are economically important (Miah and Karim, 1984). All of the fauna present in rice fields are not harmful.…”

Studies were conducted to record the abundance of arthropod insect pests and natural enemies in rice fields as influenced by rice growth stages and neighboring crops at the experimental farm of Patuakhali Science and Technology University (PSTU), Dumki, Patuakhali during 2012 in Boro rice season following randomized complete block design. Results indicated that ricetree habitat showed the highest abundance of leafhoppers (100.75) followed by cricket (16.50), grasshoppers (15.25) and stink bugs (15.25). The lowest abundance of all insect pests was in rice-sesame habitat. No significant differences were found on the abundance of rice bug, rice hispa and stem borer populations. At seedling stage, the highest abundance of leafhopper (94.25) was recorded followed by grasshopper (47.00) and stink bug (26.50) while the lowest was stem borer (0.57) and rice hispa (6.00). At early tillering stage, maximum number of grasshopper (17.25) was recorded followed by cricket (7.00). At maximum tillering stage, the highest abundance of leafhoppers (122.5) was obtained followed by rice bug (62.00) and the lowest was the stink bug (7.00). At panical initiation stage, the highest abundance of rice bug (334.00) was recorded which was followed by leafhoppers (65.25) and the lowest was the cricket (15.75). No population of rice hispa and stem borer was recorded at maximum tillering and panical initiation stages. In case of natural enemies, the highest abundance of lady bird beetle (45.27) and damselfly (16.73) was found in rice-rice habitat. The highest abundance of ichneumonid wasp (57.53) was in rice-tree habitat and ground beetle (28.80) was in ricesesame habitat. No significant differences were observed on the abundance of dragonfly, spider and dipteran fly among different habitats. Among different growth stages of rice plant, significantly the highest abundance of lady bird beetle was recorded at maximum tillering stage. The highest abundance of ichneumonid wasp and ground beetle was recorded at seedling stage. The highest abundance of damselfly, spider and dipteran fly was at early tillering stage. No significant difference was observed on the abundance of dragonfly among different rice growth stages.
