BIOCONTROL POTENTIAL OF ENTOMOPATHOGENIC FUNGUS BEAUVERIA BASSIANA (BALSAMO) AGAINST PERICALLIA RICINI (FAB.) (LEPIDOPTERA: ARCTIIDAE) LARVAE
No full textABSTRACT
In the recent study, the entomopathogenic fungus, Beauveria bassiana (Balsamo) used to evaluate its pathogenecity against Pericallia ricini Fab. (Lepidoptera: Arctiidae) third, fourth and fifth instars larvae. B. bassiana found effective at all concentrations i.e., 2x04, 2x105 and 2x106 spores ml-1 on the P. ricini, but the uppermost concentration (2.0 x106 spores ml-1) provided maximum control within short period of time (P<0.002) than the other spore concentrations. Mortality of P. ricini was observed maximum on highest concentration of 2.0x106 spores ml-1. The value of LC50 lies between 2.32x102 and 13.89x107 spores ml-1. P.ricini body weight was increased at 2.0x105 (452.7±7.8 mg) spores ml-1 followed by 2.0x106 (450.9±18.9) and 2.0x104 spores ml-1 (443.8±6.2) by testing the field efficacy of B. bassiana against P. ricini, this insect pathogenic fungus can be used as potential biocontrol agent for the management of P. ricini. Results revealed that B. bassiana caused infection and caused death.
Key words : Beauveria bassiana, Pericallia ricini, insecticidal activity, biological control potential.

The global burden of cancer attributable to risk factors, 2010–19: a systematic analysis for the Global Burden of Disease Study 2019
No full text© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods: The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk–outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings: Globally, in 2019, the risk factors included in this analysis accounted for 4·45 million (95% uncertainty interval 4·01–4·94) deaths and 105 million (95·0–116) DALYs for both sexes combined, representing 44·4% (41·3–48·4) of all cancer deaths and 42·0% (39·1–45·6) of all DALYs. There were 2·88 million (2·60–3·18) risk-attributable cancer deaths in males (50·6% [47·8–54·1] of all male cancer deaths) and 1·58 million (1·36–1·84) risk-attributable cancer deaths in females (36·3% [32·5–41·3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20·4% (12·6–28·4) and DALYs by 16·8% (8·8–25·0), with the greatest percentage increase in metabolic risks (34·7% [27·9–42·8] and 33·3% [25·8–42·0]). Interpretation: The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.
