Sixteen rice accessions were screened under greenhouse condition and field condition against yellow stem borer (YSB) during 2014-15. Six wild accessions were screened against YSB under green house condition only. In green house condition, the accessions viz., Oryza minuta, O. nivara, IR 20, IET 23710 and IET 23715 recorded the score of 3 (moderately resistant) at both phases. Under field condition, the variety TKM 6 recorded score 1 (resistant) based on dead heart and white ear damage followed by IR 20, IET 23710 and IET 23715, which recorded the score of 3 (moderately resistant) for both dead heart and white ear damage. Both under field and green house condition, IR 20, IET 23710 and IET 23715 showed moderate resistance to yellow stem borer.

Selection Of

Seven germplasm lines (IC No. 381538, 450535, 463380, 464140, 464186, 574807 and 578388) were categorised as best entries with resistance/ moderately resistant reaction at both vegetative (dead hearts)  and reproductive (white ears) stages of the rice crop through field screening trials for two successive seasons i.e., kharif, 2016 and kharif, 2017. Complex factors like behavioural, metabolic processes of the insects and biochemical constituents of the host plants are involved in resistance to rice stem borers. Exploiting the mechanism of induced resistance in rice through abiotic elicitors is the need of the hour. Keeping in view the damage of yellow stem borer and its influence on rice yield the promising seven entries were selected for biochemical analysis. The analysis revealed that entries with low sugars and low free amino acids and high total phenols, proteins, proline and silica content may confer resistance to rice yellow stem borer and can be subjugated in the breeding programme to develop resistant varieties.

Natural Parasitism

Three species of parasitoids viz., Telenomus dignus Gahan, Trichogramma japonicum, Ishii and Tetrastichus schoenobii Ferriere were recorded from the egg masses of rice yellow stem borer, Scirpophaga incertulas (Walker) in a field study. The extent of parasitism was high during Rabi (43.33 – 93.33 %) and low during Kharif (0 - 40.00 %). Parasitism by T. dignus was maximum in October (50.00 %), T. japonicum, in November (23.08 %) and T. schoenobii in February (55.55 %). dignus and T. schoenobii in combination parasitized maximum number of egg masses (41.82 %). Multiple parasitism by the three species was high in December (8.33 %) and January (7.14%). Parasitic potential was maximum, when T. schoenobii alone parasitised the egg masses followed by T. dignus and T. schoenobii in combination. Host density in the field influenced the extent of parasitism.

Co2 Concentrations

An experiment was conducted at Research Farm, National Rice Research Institute, Cuttack, Odisha, India to quantify the effect of elevated carbon dioxide (CO2) concentrations on the biology and morphometric parameters of yellow stem borer (Scirpophaga incertulas, Pyralidae, Lepidoptera). Yellow stem borer is one of the major pest of rice in the whole rice growing regions of South East Asia. The effect of three carbon dioxide concentrations i.e. 410 ppm (ambient), 550 ppm and 700 ppm on the duration of the developmental period as well as morphometric parameters of each stage of the lifecycle of the pest was analysed. It was found that, there was an increase in the duration of the developmental period of each stage of life cycle as the concentration of CO2 increases. However, the life span of the adult moth was significantly lower under the elevated CO2 concentrations when compared with ambient CO2 concentration. Morphometric parameters viz., mean length, width and weight of each larval instar, pupa and adult were found to be significantly higher in elevated concentrations of CO2 as compared to ambient concentration.

Abstract The present investigation was based on the management of Yellow stem borer which is a major pest of Basmati rice crop in India. All the treatments were applied to control this pest when it reached on its ETL level. The data recorded one day before of first spray and 3, 7, 10 days after of each spray. The observation revealed that all the treatments were found significantly superior over untreated control. Among the all treatments Fipronil 5 SC was found most effective followed by Imidacloprid 17.8 SC, Cartap hydrochlorid 4 G. Among the bio-pesticides B. bassiana was most effective after the chemical pesticides followed by M. anisopliae and V. lacani. The field treated with fipronil 5 SC produced the highest grain yield (38.35 q/ha) and Imidacloprid 17.8 SC was placed on second place with 37.26 q/ha grain yield followed by Thiamethoxam 25 WG (36.05q/ha) and Cartap hydrochloride 4G (33.87 q/ha).
