A study was undertaken to characterize the granulosis viruses (GVs) of early shoot borer, Chilo infuscatellus (Snell.) (Crambidae: Lepidoptera) and internode borer, Chilo sacchariphagus indicus (Kapur) (Lepidoptera: Crambidae) in sugarcane. Scanning electron photomicrographs revealed ovo-cylindrical occlusion bodies (OBs) of GVs in early shoot and internode borers with an average size of 425.03 and 230.21 nm, 387.64 and 208.68 nm in length and breadth respectively. Transmission electron photomicrographs also showed ovo-cylindrical OBs embedded with a rod-shaped virion. The average length and breadth of the virion in the OB was 271.0 ´ 52.6 nm, 257.0 ´ 50.2 nm for early shoot and internode borer GVs respectively. Toxicity studies with the respective GVs revealed lethal concentration values of 4.38, 4.61, 6.89 OBs/mm2 and 1.85, 135.43, 8045.27 OBs/mm2 to second, third and fourth larval instars of Chilo infuscatellus granulosis virus (ChinGV) and Chilo sacchariphagus indicus granulosis virus (ChsaGV) respectively.Keywords

Background/Objectives: Salacia chinensis L., a high valuable anti-diabetic medicinal plant of Hippocrateaceae family, possess various medicinal properties. Its anti-inflammatory, hepatoprotective and anticancer activities originated from huge number of isolated phytochemicals such as mangiferin and salacinol. Excessive and indiscriminate collection for supplement of global demands has caused classified this plant as endangered species. Establishment of an effective regeneration system for S. chinensis via direct organogenesis as a most reliable method was the main goal of this study. Methods: The explants include leaf, node and shoot tips were inoculated on Murashige and Skoog (MS) medium fortified with different concentrations and combinations of Plant Growth Regulators (PGRs) including 6-Benzylaminopurine (BAP), Kinetin (Kin), 1-Naphthalene Acetic Acid (NAA) and Indole-3-Acetic Acid (IAA) for direct regeneration by shoot formation. Findings: The most efficient shoot regeneration in terms of the proliferation percentage (87.81 ± 3.22%), number (5.37 ± 0.02) and length of shoots (3.22 ± 0.04 cm) was obtained on MS basal medium supplemented by BAP (1.0 mg/l) and NAA (0.5 mg/l). The highest frequency in vitro ischolar_main formation (91.33 ± 2.02%) with maximum number of 4.35 ± 0.03 ischolar_mains with a length of 2.47 ± 0.03 cm was successfully achieved in half strength MS medium supplemented with 2.0 mg/l IBA. Application: The established system has this potential to be successfully employed in order to conservation and masspropagation of S. chinensis for commercial utilization.Keywords

In this study, we report Phenacoccus saccharifolii (green) on sugarcane in Tamil Nadu, India, though an earlier unreported isolated occurrence was observed by us in the farmers’ fields at Pugalur, Tamil Nadu. This pest has now become a major threat to sugarcane cultivation across the state as it can often kill the infested canes with or without the association of the fungal disease, pokkah boeng. Field observations revealed that the ratoon crop was affected more than the plant crop in the same locality. This species was found in large colonies, primarily between the –2 and +1 leaf of the sugarcane plant and hence, named as crown mealybug. Infestation leads to severe mottling in the leaf whorl and death of the central shoot. To the best of our knowledge, there are no earlier studies on the occurrence of this mealybug on Saccharum spontaneum L. Well-developed colonies showed high activity of three encyrtid parasitoids, viz. Aenasius phenococci (Ashmead), Aenasius arizonensis (Girault) and Leptomastix dactylopii Howard in the areas surveyedKeywords
