June July

In India, Madhya Pradesh is the third largest lac producing state after Chhattisgarh and Jharkhand, as they contribute 12, 16 and 60%, respectively in total country’s lac production. Lac is produced in ten out of eleven agro-climatic zones of Madhya Pradesh. In total lac production of the state, Baisakhi (Butea monosperma, inoculated in October-November) crop contributes 76% followed by 19% by Katki (Butea monosperma, inoculated in June-July), 3% by Aghani (Schleichera oleosa, inoculated in June-July) and 2% by Jethwi (Schleichera oleosa, inoculated in January-February). Ranchi was leading lac producing district followed by Simdega, Gumla, Khunti of Jharkhand and Seoni district of Madhya Pradesh. Increasing summer temperature up to 45 ⁰C, the country’s lac production was declined from 20,050 tons in 2003-04 to 16978 tons in 2014-15. In case of biotic factors, Tachardiaephagus tachardiae and Tetrastichus purpureus are the most abundant lac associated parasites and Eublemma amabilis and Pseudohypatopa pulverea are the most destructive key predators of lac insects. By combating these hindrances, lac cultivation generated an employment for 16-160 man days. Lac cultivation produces maximum gross return (Rs. 9,77,600) from 100 Kusum host plants, and the highest Benefit-Cost (6.80) ratio was recorded for Ber-kusumi (Ziziphus mauritiana- Schleichera oleosa) crop in Ranchi, Jharkhand. In this context, the study finds out obstacles in lac production of India and suggests some control measures to improve lac producing peoples’ livelihood.

Lac Insect

Surveys were conducted in 28 districts of Bihar for occurrence of natural population of lac insect; Kerria lacca Kerr (Hemiptera, Tachardiidae), and abundance of its host plant. Naturally occurring lac insect was observed in 18 districts in varied proportion mostly on Ficus religiosa, Ficus benghalensis and rarely on Ziziphus mauritiana and Butea monosperma. Majority of insects were found dead but at few places good live population were noticed. Natural occurrence of lac insect was found highly vulnerable to human interventions, high temperature and parasitoids and predators. Out of 17 districts of south Bihar, falling under zone III, 10 districts were found rich in naturally surviving lac insect. Lac insects in scattered manner were also observed in many districts of Northern Bihar but occurrence and population densities were very low. Survey revealed the abundance of lac host and natural population of lac insects in various districts of zone III (58%) of Bihar. These findings could open a new window for introduction lac cultivation in these areas for livelihood support to resource poor farmers, especially during off-agricultural season.

Jharkhand agriculture a rainfed one characterized with ninety percent cultivable area monocropped with rice only. On one hand there is need to enhance productivity of agricultural crop, other hand priority should be given for profit enhancement. Lac is a major source of rural livelihood in Jharkhand. Major lac host species like Butea monosperma (palash), Zizyphus mauritiana (ber) and Schleichera oleosa (kusum)are available in plenty in forest as well as on own gravel upland which is otherwise not under cultivation and are wasteland.  Diversifying the existing agriculture system through inclusion o lac not only enhances the profit margin of the production system but also developed entrepreneurial behavior of the main actor of the system.  In this background lac cultivation interventions was introduced in rice based monocropping system. Inclusion of Lac on abandoned tree of Butea monosperma and Zizyphus mauritiana fetch good economic return to the farm families with net return of Rs.  25090 per hectare and Rs. 7480/ha respectively from kusumi lac on and rangeeni lac, whereas in upland rice net return was only Rs. 3804/ha. The benefit per rupee of investment is lowest in case of growing only rice with Rs. 2.08 and maximum benefit was Rs. 5.14 in case of lac on ber. Lac cultivation on different host trees were compaered and it was found that benefit per rupee of investment were Rs. 3.59, 4.83, and 2.41. and 2.08 respectively in rice with lac cultivation of rangeeni on palash, rice with kusumi lac on ber, rice with lac on palash and ber in alternate season   and cultivation of  only rice crop. Organizing Lac cooperative and input bank at kisan club proved a pivot in better management of produce and ensuring local availability of brood lac.

O controle da broca-da-erva-mate, Hedypathes betulinus, limita-se ao emprego de práticas silviculturais e catação manual dos insetos adultos, não sendo permitido o uso de inseticidas químicos na cultura. Esta pesquisa teve por objetivos verificar a presença natural de Beauveria bassiana no solo de plantio em monocultura de erva-mate, determinar a persistência de B. bassiana no solo após duas e três aplicações do fungo e averiguar a influência de fatores abióticos na estabilidade do fungo no solo. O estudo foi conduzido em um erval no município de Campo Alegre, Santa Catarina, Brasil, onde foram coletadas amostras de solo em duas áreas, para avaliação da presença natural de inóculos do fungo B. bassiana, procedendo-se à contagem, isolamento e identificação.Não foi detectada a ocorrência natural do fungo no solo em nenhuma das duas áreas. Após essa confirmação, foram realizadas pulverizações com B. bassiana em ambas as áreas, sendo que em uma ocorreram duas e na outra três aplicações. Após a última pulverização, realizada em fevereiro/2006, verificou-se que os inóculos do fungo persistiram por 90 dias na área com duas aplicações e 120 dias na área com três aplicações. A temperatura afetou a persistência do fungo no solo em ambas as áreas, mas a umidade relativa não mostrou influência sobre os inóculos em campo.Palavras-chave: Broca-da-erva-mate; controle biológico; epizootia; fungo entomopatogênico. AbstractPersistence in soil of inoculum of Beauveria bassiana used to control Hedypathes betulinus in yerba maté plantation, Ilex paraguariensis. Control measures of Hedypathes betulinus are restricted to agricultural practices and hand picking of adult insects. No chemical control is allowed in yerba maté cultivation areas. The objectives of this research were to verify the natural occurrence of the entomopathogenic fungus Beauveria bassiana in the soil of yerba maté in monoculture; to determine the persistence of inoculums in the soil after applications of the fungus; and to evaluate the influence of abiotic factors on fungus stability in the soil. The soil samples were taken from two experimental areas in a yerba maté plantation in the county of Campo Alegre, Santa Catarina, Brazil. The samples were analyzed in order to count, isolate and identify inoculums of B. bassiana and other fungi. After the confirmation that B. bassiana was not present in the soil, a suspension of the fungus was applied, twice in one of the areas and three times in the other. After the last application in February/2006, the inoculum persisted for 90 and 120 days, in the area with two and three applications, respectively. The temperature affected the persistence of B. bassiana in soil; however, the relative humidity did not.Keywords: Biological control; epizooty; entomopathogenic fungus; wood borer.

AbstractEntomopathogenic fungi show great promise as pesticides in terms of their relatively high target specificity, low non-target toxicity, and low residual effects in agricultural fields and the environment. However, they also frequently have characteristics that limit their use, especially concerning tolerances to temperature, ultraviolet radiation, or other abiotic factors. The devastating ectoparasite of honey bees, Varroa destructor, is susceptible to entomopathogenic fungi, but the relatively warm temperatures inside honey bee hives have prevented these fungi from becoming effective control measures. Using a combination of traditional selection and directed evolution techniques developed for this system, new strains of Metarhizium brunneum were created that survived, germinated, and grew better at bee hive temperatures (35 °C). Field tests with full-sized honey bee colonies confirmed that the new strain JH1078 is more virulent against Varroa mites and controls the pest comparable to current treatments. These results indicate that entomopathogenic fungi are evolutionarily labile and capable of playing a larger role in modern pest management practices.

Great Damage

Caterpillars of the moth Holcocera pulverea, Meyr., along with those of Eublemma amabilis, Moore, do great damage to lac cultivation by feeding upon the living insects. Misra* and Imms & Chatterjee† have pointed out that H. pulverea may be found in even greater numbers than E. amabilis, though the predacious nature of the latter is more generally recognised. I have been able to confirm this observation with North Indian species of lac insects growing on Butea frondosa and Schleichera trijuga. However, in South India the wild species of lac, Lakshadia communis, at least in Mysore, is entirely free from the attack of H. pulverea, while Lakshadia mysorensis, the species commercially cultivated on Shorea talura, is never attacked by H. pulverea to the same extent that it is by Eublemma amabilis. With L. mysorensis this is partly due to H. pulverea being heavily parasitised. In the pupal stage this moth is attacked by the Chalcid, Eurytoma pallidiscapus, Cam. Imms & Chatterjee mention that only four examples of this parasite were reared by them during the entire course of their study, indicating its rare association with North Indian species of lac insects. In Mysore it is far from being scarce, which has enabled its life-history to be traced as a pupal parasite of H. pulverea. Fig. 1, a, shows a pupa of this moth from which a female, Eurytoma pallidiscapus, was reared on 14th November 1922.

Mastitis is an inflammation of mammary glands that is prevalent in dairy bovines. It causes a significant proportion of economic losses to the dairy farmers in India. Cattle and buffalo farming contribute significantly to the economy of the state. Various infectious agents such as bacteria, fungi, and algae may cause mastitis. Hence, it is essential to understand the etiological agents and predisposing factors that lead to mastitis in susceptible bovine populations in Madhya Pradesh state so that appropriate prevention and control strategies can be implemented. In this chapter, epidemiology, diagnosis, prevention, and control measures of mastitis in general and in India, the state of Madhya Pradesh, in particular, will be presented.

This paper presents the results of the study of the population levels of the gypsy moth in the forests of National Park Đerdap, over the period 1996-2014. The characteristics of three outbreaks (1996-1997, 2003-2005 and 2009-2014) of the gradogenic character were studied. Since these are forest ecosystems of the natural protected areas in which the special rules and measures aimed at the protection from the adverse effect of the wide range of the biotic and abiotic factors are applied, with the special emphasis on the possible, or impossible, use of pesticides, the paper also analyzes the control measures which were taken, i.e. the reduction of the density of the gypsy moth to the normal population level. In addition, the effect of two species of egg parasitoids, as well as of Entomophaga maimaiga and Lymantria dispar multicapsid nuclear polyhedrosis virus (LdMNPV) - pathogenic worms, on the population level of the gypsy moth in some years of the outbreak was studied.
