Crop protection in South Asia is predominately based on chemical pesticides in spite of its adverse effects of human health and environment. Concurrent with the removal of some of the highly toxic compounds has been the development of alternative crop protection approaches such as integrated pest management (IPM) which can accommodate the use of microbial pesticides as an integral component. Though there has been considerable research and development activities focused on microbial pesticides by research institutions of SAARC countries, the registered products coming out and extent of agricultural lands under microbial pesticide use is negligible in most countries except India. The increasing consumer demand for health food commodities without pesticide residues and global export horticultural standards are the drivers for microbial pesticide use. However, the microbial pesticide use in South Asia is lagged behind compared to other regions. The consultation was organized to understand the modalities which support the use of microbial pesticides in South Asia. National Focal Point Experts from SAARC Member Countries and a couple of invited experts shared their knowledge and experiences towards the facilitating of microbial pesticide use in the South Asia. It was evident that production and availability of microbial pesticides are not issues in most cases. But there is technology gap on storage, packaging, delivery and application. Further regulatory hurdles, registration formalities, Intellectual Property Rights, export/import, political interference and several other concerns are required due attention and regional harmonization for facilitating the microbial pesticide uses. I strongly believe this publication titled “Facilitating Microbial Pesticide Use in Agriculture in South Asia” is a comprehensive overview of microbial pesticide production, registration, regulation and use in South Asia and bring out value recommendations for facilitating the microbial pesticide use in South Asia.

Wickramaarachchi SAARC Agriculture Centre, BARC Complex, Farmgate Dhaka 1215, Bangladesh Email: [email protected] Abstract Reliance on chemical pesticides for crop production has caused several detrimental effects such as pesticide resistance, pest resurgence and outbreak of secondary pests which reflect the repeated and over use of chemical pesticides to achieve the expected level of control. To overcome the hazards associated with chemical pesticides, the use of bio- pesticides which are derived from plants and microorganisms is increasingly being adopted. Out of all the bio-pesticides used today, microbial bio-pesticides constitute the largest group of broad-spectrum bio-pesticides. Microbial control agents based on naturally occurring fungi, bacteria, viruses or nematodes have offered some realistic alternatives to chemical pesticides. Microbial pesticides have gained attention because of their relatively low toxicity, potential for local production and compatibility with smallholder farming. However, the widespread use of microbial pesticides in South Asia has been restricted owing to various constraints at the developmental, registration and production levels. Efficacy of microbial pesticide in field is highly dependent on the environment conditions. There are potential problems associated with contamination, formulation potency, attenuation of pesticide activity and shelf life. To deal with all these aspects require equipment, expertise, material and capital. Microbial pesticides are regulated by systems designed originally for chemical pesticides that have created market entry barriers by imposing burdensome costs on the microbial pesticide industry. Regulatory authorities generally require bulk information on a microbial pesticide for characterization, assessing its potential risks on human and environment and confirming its effectiveness against pest. There are no properly defined and harmonized regulatory procedures for microbial pesticides in most of South Asian counties. Lack of regional harmonization in enabling regulations is one of the most important barriers to the wider implementation of microbial pesticides. Couple of areas has to be strengthened for facilitating and microbial pesticide development and adaptation. They include increasing the product range aiming the major plant protection issues, development 1 of resilient microbes, ensuring the quality and quantity available in the market, improving storage and quality control, introducing policies to promote microbial pest control strategies, ensuring favorable intellectual property rights for researching, create a healthy regulatory environment, regulatory harmonization across the region and encouraging public private partnerships to attract more SMEs into the microbial pesticide industry. Key words: Microbial pesticides, registration, regulation, commercialization Introduction The world population is projected to grow by 34 percent from 6.8 billion today to 9.1 billion in 2050. In order to meet the demand of increasing population, the global demand for food, feed and fiber is expected to grow by 70 percent while crops may also be increasingly used for bio- energy and other industrial purposes. It is estimated that demand for food in South Asian region will increase by 40 percent by 2050 due to rapid population growth along with climate volatility. At present, South Asia is home for 27 present of global population. Further, 40 percent of poor people and 35 percent

Field testing of the candidate chemicals, indole, phenol, and anisole, both alone and as binary mixtures, led us to conclude that anisole was the major component of the sex pheromone. Neither male nor female beetles were attracted to indole or phenol on their own. Similarly, when indole and anisole were combined, the attractiveness of the solution did not increase over that obtained with anisole alone.

Sivakumar1*, M. Kannan2, V. Ramesh Babu3, M. Mohan1, Surabhi Kumari1, R. Rangeshwaran1, T. Venkatesan1 and Chandish R. Ballal1 Abstract Jute hairy caterpillar, Spilosoma (=Spilarctia) obliqua (Walker) (Arctiidae: Lepidoptera), is an irregular and polyphagous insect pest that occurs all over India. A severe natural viral epizootic was observed in the field population of S. obliqua in jute. The virus was characterized as Spilosoma obliqua nucleopolyhedrovirus (SpobNPV NBAIR1) based on morphological, biological, and molecular characterization. Under scanning and transmission electron microscopy (SEM and TEM), the occlusion bodies (OBs) of SpobNPV NBAIR1 appeared as both tetrahedral and triangular with the size ranged from 1.04-1.72 μm. The results on the bioassay studies revealed that the lowest 2 LC50 value of 2.93 OBs/mm by leaf disc bioassay against the second instar S. obliqua showed its high virulence. The identity of SpobNPV was further confirmed by the amplification of polyhedrin gene (NCBI GenBank accession no. MK288145). Eleven species of lepidopteran insects, viz., Spodoptera litura, S. exigua, S. frugiperda, Helicoverpa armigera, Plutella xylostella, Amsacta albistriga, Maruca vitrata, Trichoplusia ni, Pieris brassicae, Agrotis ipsilon, and Bombyx mori, were not susceptible to the infection with SpobNPV NBAIR1. Field experiments on jute crop revealed 68.92, 78.59, and 93.16% reduction in larval population of S.

It damages seedlings and adult palms by feeding on roots, boring the bole and collar regions. Understanding the ethology of the pest would aid to develop an ecofriendly pest management strategy. Though control measures have been developed, imperative need is there to search for newer method. On this line it was attempted to study the adult emergence pattern during 2011-2013 in root grub infe, Kerala. Adult emergence initiated on receipt of summer shower in third week of April in 2011, 2012 and 2013. The peak emergence attained during June, after the receipt of >200 mm rainfall. The emergence commenced when illuminance fell down to 124.37±75sted coconut gardens (N12º31.550’ E074 º58.081’) at CPCRI experimental farm, Kasaragod.5lx in the evening and prolonged up to 1.2±04lx. However, heavy rainfall during this part of the day delayed/stopped the emergence. Maximum swarming occurred at 32.6±15.1lx. Female emergence and mating started at 12.04±8.1 lx. The operational sex ratio was wider during initial days of emergence, which narrowed down in subsequent days.
