  • development of new germplasm in sorghum with desirable agronomic traits and resistance to shootfly Atherigona soccata rondani and stemborer chilo partellus swinhoe
    Journal of entomological research, 2006
    Co-Authors: Prem Kishore, Vinita Mittal


    The released varieties and hybrids developed from Temperate x Tropical crosses, despite having high yield potential and other agronomic traits failed to express in full due to the attack of key pests of sorghum, viz., the shootfly, Atherigona soccata Rondani and stem borer, Chilo partellus (Swinhoe). To overcome ensuing problem large number of crosses by crossing intermediate derivative (in resistance) with intermediate derivative (in resistance) and resistant with intermediate derivative were made and evaluated against the two pests. Many new sources of resistance with desirable agronomic traits have been located in this newly developed germplasm.

  • feasibility of integrating microbial inoculants and host plant resistance for managing shootfly Atherigona soccata rond in sorghum
    Journal of entomological research, 1998
    Co-Authors: Prem Kishore


    The compatibility of nitrogen fixing bacteria, viz, Azospirillum brasilense and Pseudomonas siraiata with resistant varieties, viz., P 311 and SPV 1015 in sorghum was evaluated against the shoot fly, Atherigona soccata Rondani. In the case of sorghum cultivar P 311 inoculated with Azospirillum and Pseudomonas, the percentage dead-hearts was 9.8 and 11.2, respectively. Similarly, dead-hearts formed in SPV 1015 due to A. soccata were respectively 8.7 and 10.5 per cent with these two microbial inoculants as against 82.0 per cent in CSH-1 (check). Such combination resulted in significant reduction of dead-hearts in both the cultivars. Consequently, the increased average grain yield, i.e., 61.7 and 69.4 per cent in P 311 and SPV 1015 sorghum cultivars, respectively, manifested with both the inoculants. The strategy thus evolved would provide economical, easily acceptable and ecology based management of this key borer pest of sorghum.

  • response of sorghum variety pusa chari 121 to carrier based inoculants azotobacter and azospirillum fermented residue and shootfly Atherigona soccata rondani under field conditions
    Journal of entomological research, 1998
    Co-Authors: Prem Kishore


    A new sorghum variety Pusa chari-121 (PC-121) was developed from PC 7xCSV-1 through pedigree selection. It is endowed with good agronomic attributes, better yield and moderate level of resistance to shootfly (Atherigona soccata Rondani) under multilocation trials. This variety responded well to carrier based inoculants, Azotobacfer, Azospirillum and fermented residue by showing improvement in agronomic parameters, viz, green fodder yield, cane yield, and total soluble sugars. Seed inoculation with Azospirillum significantly reduced the formation of dead-hearts due to shootfly. Azotobacter with fermented residue was the next best treatment in reducing shootfly dead-hearts. Azosplrillum with enormous potential for fixing atmospheric nitrogen not only facilitated in reducing the dosages of chemical fertilizer but also showed great promise in reducing the dead-heart formation by shootfly.

  • mechanisms and diversity of resistance to sorghum shoot fly Atherigona soccata
    Plant Breeding, 2015
    Co-Authors: Belum V S Reddy, Mohammed Riyazaddin, Polavarapu Kavi B Kishor, Ashok A Kumar, Rajendra S Munghate, H C Sharma


    Sorghum shoot fly, Atherigona soccata, is one of the important pests of postrainy season sorghums. Of the 90 sorghum genotypes evaluated for resistance to this pest, RHRB 12, ICSV 713, 25026, 93046 and 25027, IS 33844-5, Giddi Maldandi and RVRT 3 exhibited resistance in postrainy season, while ICSB 463, Phule Anuradha, RHRB 19, Parbhani Moti, ICSV 705, PS 35805, IS 5480, 5622, 17726, 18368 and 34722, RVRT 1, ICSR 93031 and Dagidi Solapur showed resistance in rainy season, suggesting season-specific expression of resistance to A. soccata. ICSB 461, ICSB 463, Phule Yasodha, M 35-1, ICSV 700, 711, 25010, 25019 and 93089, IS 18662, Phule Vasudha, IS 18551 and 33844-5 and Barsizoot had fewer deadhearts than plants with eggs across seasons, suggesting antibiosis as one of the resistance mechanism. Five genotypes exhibited resistance with high grain yield across seasons. Correlation, path and stepwise regression analyses indicated that leaf glossiness, seedling vigour, trichome density, oviposition and leaf sheath pigmentation were associated with the expression of resistance/susceptibility to shoot fly, and these can be used as marker traits to select and develop shoot fly-resistant sorghums.

    Sorghum shoot fly, Atherigona soccata is one of the most important pests of dual-purpose sorghums during the postrainy season in India. Therefore, it is important to identify stable sources of resistance to develop cultivars with shoot fly resistance and adaptation to postrainy season. We evaluated 190 lines adapted to the postrainy season across five locations, of which 30 lines were identified with resistance to A. soccata. These lines were further evaluated for three seasons across five locations to identify lines with stable resistance to this pest across seasons and locations. Data were recorded on oviposition non-preference, deadheart incidence, recovery resistance, morphological traits (leaf glossiness, seedling vigor, plant height and days to 50% flowering), and grain yield. The sorghum genotypes CSV 22, ICSB 422, ICSB 425, ICSB 428, ICSB 432, ICSB 458, ICSB 463, IS 2312, IS 5480, IS 18662, Phule Chitra, RSV 1093, IS 18551, and RSV 1235 exhibited resistance to shoot fly damage across seasons, of which ICSB 425, ICSB 428, ICSB 432, IS 2312, IS 5480, and IS 18551 showed non-preference for oviposition. Six genotypes (ICSB 425, IS 2312, IS 18662, RSV 1090, RSV 1093, and IS 18551) also showed good recovery resistance following shoot fly damage. Principal coordinate analysis placed the maintainer lines (B-lines) with shoot fly resistance in two clusters with ICSB 422, ICSB 432, ICSB 435, ICSB 456 and ICSB 458 in one cluster and ICSB 425, ICSB 428 and ICSB 463 in the other; the open pollinated varieties/germplasm lines (restorers) were placed in a different group (CSV 22, IS 5480, IS 2312 and RSV 1093), suggesting the possibilities for developing hybrids with adaptation to the postrainy season. Based on regression coefficient and deadheart incidence, the genotypes IS 2312, ICSB 425, RSV 1090 and ICSB 428 were stable in expression of resistance to shoot fly across seasons and locations. The genotypes CSV 22 and RSV 1093 exhibited high grain yield potential and resistance to shoot fly damage, while Phule Yashoda, IS 2312, RSV 1235, and ICSV 574 were moderately resistant to shoot fly damage, but had high grain yield potential. These genotypes can be used in sorghum improvement for developing cultivars with shoot fly resistance, high grain yield and adaptation to postrainy season.

  • constitutive and inducible resistance to Atherigona soccata diptera muscidae in sorghum bicolor
    Journal of Economic Entomology, 2012
    Co-Authors: H C Sharma, Siva K Chamarthi, Peter M Vijay, Lakshmi Narasu


    Host plant resistance is one of the important components for minimizing the losses because of sorghum shoot fly, Atherigona soccata (Diptera: Muscidae) attack. Therefore, we studied the constitutive and inducible biochemical mechanisms of resistance to A. soccata in a diverse array of sorghum genotypes to identify lines with diverse mechanisms of resistance to this insect. Fifteen sorghum genotypes with different levels of resistance to A. soccata were evaluated. Methanol extracts of 10-d old damaged and undamaged sorghum seedlings were subjected to high-performance liquid chromatography analysis. Association between peak areas of the identified and unidentified compounds with parameters measuring A. soccata resistance was determined through correlation analysis. Amounts of p-hydroxy benzaldehyde and the unidentified compounds at RTs 24.38 and 3.70 min were associated with susceptibility to A. soccata. Genotypes exhibiting resistance to A. soccata were placed in four groups, and the lines showing constitutive and/ or induced resistance to A. soccata with different combinations of biochemical factors potentially could be used for increasing the levels of resistance to A. soccata in sorghum.

  • evidence of shoot fly Atherigona soccata rondani dipt muscidae oviposition response to sorghum seedling volatiles
    Journal of Applied Entomology, 1998
    Co-Authors: K F Nwanze, F E Nwilene, Y V R Reddy


    The effects of Atherigona soccata-resistant (IS 18551) and -susceptible (CSH 5) sorghum seedling volatiles on oviposition by the pest were investigated by exposing mated females to various treatments under greenhouse conditions. It is hypothesized that susceptible-genotype and younger (5-10 days after emergence, (DAE)) seedlings emit different quantities and/or blends of volatiles than resistant or older (14-21 DAE) ones. A. soccata response was greater to host plant odour alone than to host plant plus fishmeal. A transparent trap with 10-day-old susceptible seedlings was found to be more effective and efficient for adult attraction than the other two types of traps (live fly trap and black trap). The present study indicated that females of A. soccata are attracted both to the volatiles emitted by the susceptible seedlings, and to phototactic (optical) stimuli that may facilitate orientation to its host for oviposition, but volatile blends associated with adult attraction will be reported in due course to confirm these results.

  • fecundity and diurnal oviposition behaviour of sorghum shoot fly Atherigona soccata rondani diptera muscidae
    Entomon, 1998
    Co-Authors: K F Nwanze, F E Nwilene, Y V R Reddy


    The fecundity and diurnal oviposition behaviour of Atherigona soccata was studied on CSH 5, a susceptible sorghum genotype, under greenhouse conditions. The fecundity of females deprived of 10-day-old sorghum seedlings was drastically reduced, and no fertile eggs were laid after 11 days of host deprivation. However, when the females were provided with host plants, egg production was prolonged, and fell considerably after the flies reached 22 days of age. There were three distinct peaks (6-7, 13-14 and 18-19 days of age) in egg-laying activity. Further studies with flies of three age groups (7, 13 and 19 days old) did not show significant differences in diurnal oviposition pattern with age. However, most eggs (60%) were laid between 08.00 and 12.00 h. It was evident from the present study that the prolonged egg-laying capacity of female A. soccata when provided with a susceptible host may partly account for the dramatic increase in damage as the crop season advances, since there would be a geometric increase in active females with every new generation of flies.

  • leaf surface wetness in sorghum and resistance to shoot fly Atherigona soccata role of soil and plant water potentials
    Annals of Applied Biology, 1994
    Co-Authors: P Soman, K F Nwanze, D R Butler, K B Laryea, Y V R Reddy



    In experiments with potted plants, the relationships between soil matric potential, plant water potential and production of water droplets (leaf surface wetness) on the folded central whorl leaf of seedlings of sorghum genotypes that are either resistant or susceptible to shoot fly (Atherigona soccata) damage were investigated. Differences in soil matric potentials in the pots affected the plant water status, which in turn had profound effects on the production of water droplets on the central whorl leaf of the sorghum genotype susceptible to shoot fly. There was no consistent variation in the relationship between plant water potential and soil matric potential of resistant and susceptible sorghum genotypes. However, there was very little or practically no water droplets on the central whorl leaf of the resistant genotypes, indicating that the production of water droplets is not solely the result of internal water status of the plant. It is suggested that leaf surface wetness is genetically controlled and that an understanding of the mechanism by which water is transferred to the leaf surface will enhance breeding for resistance to shoot fly.
