“…One possible reason is that, at these fertilization levels, plants were intrinsically ready to tiller to the greatest extent irrespective of being infested or not. However, these plants can be perceived to compensate for stem borer injury in other ways, such as increasing productive tiller numbers (Luo, 1987;Islam and Karim, 1997), increasing photosynthesis rate by leaves adjacent to damaged leaves, and translocating assimilates from injured tillers to healthy tillers (Rubia et al, 1996), and producing more and heavier grains per panicle (Akinsola, 1984;Luo, 1987;Islam, 1990;Islam and Karim, 1997).…”

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.

“…This is apparently due to the ability of rice plants to compensate for foliage removal. Rubia et al (1996) studied the mechanisms of compensation of rice plants to yellow stem borer, Scirpophaga incertulas (Walker), injury. Compensation mechanisms included increased tillering, an increased percentage of effective tillers, and an increased grain weight of damaged plants.…”

“…Thus, the earlier in the plant growth stage the injury occurs, the more rapidly the plants can compensate by translocating assimilates from injured to healthy tillers. Rubia et al (1996) cited studies by Wareing et al (1968), Meidner et al (1970) and Daley and McNeil (1987) in suggesting two reasons for compensation. First, because partial defoliation can cause increased photosynthesis in the remaining leaves, it allows an improved supply of cytokinins to the remaining leaves by removal of sinks, and leads to an increase in carboxylation enzymes.…”

“…However, yield loss is highly dependent on the age of the plant when defoliation occurs, and plants can recover and compensate for defoliation damage, even resulting in yields higher than those of undamaged plants (Taylor, 1972). Rice crops have the capacity to compensate for stem borer injury when it occurs at the vegetative stage (Rubia et al, 1996). Compensation is possible via production of new tillers (Akinsola, 1984;Viajante and Heinrichs, 1987) and by increasing the number of productive tillers (Luo, 1987) and grain weight (Akinsola, 1984;Luo, 1987).…”

Field experiments were conducted to investigate the impact of simulated insect-caused defoliation on irrigated rice. Defoliation levels tested were 0% (control), 25% defoliation at 21 days after transplanting (dat), 25% defoliation at 41 dat, 25% defoliation at 21 and 42 dat, 50% defoliation at 21 dat, 50% defoliation at 42 dat, 75% defoliation at 21 dat, 75% defoliation at 42 dat, 75% defoliation at 21 and 42 dat, 100% defoliation at 21 dat, and 100% defoliation at 21 and 42 dat. Tiller height, total number of tillers, per cent panicle-bearing tillers, weight of 100 grains and grain yields were recorded. The rice plant when defoliated just before tillering or in the tillering stage has the ability to compensate for defoliation damage. No yield losses occurred at 25% defoliation. Defoliation of 100% had a significant effect on the total number of tillers and on grain yield. Yield losses at 100% defoliation over the 3 years of the study averaged 40% in the 21 dat treatment and 55% in the 21 and 42 dat treatment. The implications of the development of cultural practices to manage lowland rice defoliating insects are discussed.

“…These correlations might have resulted from growth or/and physiological compensations in the injured plants. Compensation in rice plants due to stem borer attack has been well documented in earlier studies (Lu, 1987;Sun and Du, 1992;Rubia et al, 1996;Jiang and Cheng, 2003). They might also have resulted from preference of stem borers for infesting larger plants where higher injury levels consequently occurred, or from some other unmeasured plant attributes to which stem borers respond.…”

Abstract:The rice water weevil (RWW) Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae) is an invasive insect pest of rice Oryza sativa L. in China. Little is known about the interactions of this weevil with indigenous herbivores. In the present study, adult feeding and population density of the weevil, injury level of striped stem borer Chilo suppressalis (Walker) (Lepidoptera: Pyralidae) and pink stem borer Sesamia inferens (Walker) (Lepidoptera: Noctuidae) to rice, as well as growth status of their host plants were surveyed in a rice field located in Southeastern Zhejiang, China, in 2004 with the objective to discover interspecific interactions on the rice. At tillering stage, both adult feeding of the weevil and injury of the stem borers tended to occur on larger tillers (bearing 5 leaves) compared with small tillers (bearing 2~4 leaves), but the insects showed no evident competition with each other. At booting stage, the stem borers caused more withering/dead hearts and the weevil reached a higher density on the plants which had more productive tillers and larger root system; the number of weevils per tiller correlated negatively with the percentage of withering/dead hearts of plants in a hill. These observations indicate that interspecific interactions exist between the rice water weevil and the rice stem borers with negative relations occurring at booting or earlier developmental stages of rice.
