References AESA BASED IPM PACKAGE FOR TEA Tea-Plant description: Camellia sinensis is native to East commonly called as tea belong to family Theaceae, South and Southeast Asia, but it is today cultivated across the world in tropical and subtropical regions. It is an evergreen shrub or small tree that is usually trimmed to below 2 m (6.6 ft) when cultivated for its leaves. It has a strong taproot. The flowers are yellow-white, 2.5– 4 cm (0.98–1.57 in) in diameter, with 7 to 8 petals. The leaves are 4–15 cm (1.6–5.9 in) long and 2–5 cm (0.79–1.97 in) broad. Fresh leaves contain about 4% caffeine. The young, light green leaves are preferably harvested for tea production; they have short white hairs on the underside. Older leaves are deeper green. Different leaf ages produce differing tea qualities, since their chemical compositions are different. Usually, the tip (bud) and the first two to three leaves are harvested for processing. The leaves have been used in traditional Chinese medicine and other medical systems to treat asthma (functioning as a bronchodilator),angina pectoris, peripheral vascular disease, and coronary artery disease. The seeds of Camellia sinensis and Camellia oleifera can be pressed to yield tea oil, a sweetish seasoning and cooking oil that should not be confused with tea tree oil, an essential oil that is used for medical and cosmetic purposes, and originates from the leaves of a different plant, while both green and black teas may protect against cardiovascular disease.

AGRO-ECOSYSTEM ANALYSIS (AESA) BASED INTEGRATED PEST MANAGEMENT (IPM) A. AESA: The IPM has been evolving over the decades to address the deleterious impacts of synthetic chemical pesticides on environment ultimately affecting the interests of the planters. The economic threshold level (ETL) was the basis for several decades but in modern IPM (FAO 2002) emphasis is given to AESA where planters take decisions based on larger range of field observations. The health of a plant is determined by its environment which includes physical factors (i.e. soil, rain, sunshine hours, wind etc.) and biological factors (i.e. pests, diseases and weeds). All these factors can play a role in the balance which exists between herbivore insects and their natural enemies. Understanding the intricate interactions in an ecosystem can play a critical role in pest management. Decision making in pest management requires a thorough analysis of the agro- ecosystem. Planters have to learn how to observe the crop, how to analyze the field situation and how to make proper decisions for

But the question comes in the tea planters’ mind whether there is any adverse effect of such traps on the natural enemy complex of tea pest. In view of this, the present study was undertaken in organically managed tea garden of Meghalaya having higher diversity and density of natural enemies. The study revealed that there is no negative impact on natural enemy population concerning the use of yellow sticky traps. In addition a clear picture was received on type of arthropods trapped in the sticky traps.

To date, more than 32 viruses have been used to control insect pests in agriculture, forestry, pastures, and domestic gardens in China. In 2014, 57 products from 11 viruses were authorized as commercial viral insecticides by the Ministry of Agriculture of China. Approximately 1600 tons of viral insecticidal formulations have been produced annually in recent years, accounting for about 0.2% of the total insecticide output of China. The development and use of Helicoverpa armigera nucleopolyhedrovirus, Mamestra brassicae nucleopolyhedrovirus, Spodoptera litura nucleopolyhedrovirus, and Periplaneta fuliginosa densovirus are discussed as case studies. Additionally, some baculoviruses have been genetically modified to improve their killing rate, infectivity, and ultraviolet resistance. In this context, the biosafety assessment of a genetically modified Helicoverpa armigera nucleopolyhedrovirus is discussed. Keywords: viral insecticides; commercialization; genetic modification 1. Introduction Research on insect viruses in China started with the Bombyx mori nucleopolyhedrovirus in the mid-1950s [1] and, to date, more than 200 insect virus isolates have been recorded in China.

    Zootaxa 3262: 22–34 (2012) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ Article ZOOTAXA Copyright © 2012 · Magnolia Press ISSN 1175-5334 (online edition) Taxonomic remarks on Andraca Walker, 1865 (Lepidoptera: Bombycidae) with descriptions of five new species VADIM V. ZOLOTUHIN Department of Zoology, State Pedagogical University of Ulyanovsk, pl. Lenina 4, RUS-432700, Ulyanovsk, Russia. E-mail: [email protected] Abstract The genus Andraca Walker, 1865, is divided into two subgenera, one of them new: Chrypathemola Zolt., subgen. nov. (type species Andraca apodecta Swinhoe, 1907). The following new species are described: Andraca draco, sp. nov. (from Java); Andraca lawa, sp. nov. (from Palawan), Andraca paradisea, sp. nov. (from Philippines), Andraca chrysocollis, sp. nov. (from Philippines) and Andraca (Chrypathemola) nobilorum, sp. nov. (from Vietnam). A male lectotype for Andraca bipunctata Walker, 1865 is designated from the collection of ZMHU; this designation led to the new synonymy: Andraca bipunctata Walker, 1865 = Andraca angulata Kishida, 1993, syn. nov. The systematics of the family Bombycidae is briefly discussed. Key words: Lepidoptera, Bombycidae, Oberthuerinae, Andraca, new species, new synonymy, taxonomy Introduction This article describes new species and taxonomic arrangements in the bombycid genus Andraca Walker, 1865. The members of the genus Andraca are of non-bombycid external appearance—with broad and short wings, mostly with apex pointed to falcate, with a characteristic tuft of scales on the anal margin of the hind wing (a character typical for the Bombycidae, s. lat., and formerly treated as an autapomorphy of the family). The genus was established in Bombycidae, transferred to the Notodontidae by van Eecke (1921, Tijdschr.

    CCHHAAPPTTEERR 11 IINNTTRROODDUUCCTTIIOONN 1.1. TEA: JOURNEY FROM THE WILDERNESS TO THE CUP OF CIVILIZATION Tea [Camellia sinensis (L.) O. Kuntze] is an evergreen plant that is cultivated in tropical and sub-tropical climates for its leaves, which are dried, fermented, processed and consumed as much-loved beverage. For centuries tea has been an integral part of people around the globe for its refreshing aromatic flavor which invigorates billions of life every morning with its first sip. In fact after water, tea is the second most consumed beverage in the world (van der Wal, 2008). It was discovered in around 2700 BC, crowning it to be one of the oldest beverages in the world. It has been an integral part of human civilization for having tremendous medicinal, commercial and cultural value. The genus Camellia belongs to the family Theaceae. It was first elaborately described by Sealy in 1958 with reported 82 species, classified into 12 sections. Chang (1998) later rearranged the native Chinese Camellia into 280 species under four subgenera and 22 sections. All Camellia spp. does not produce the globally renowned beverage ‘tea’ (Benerjee, 1988), in fact many species are cultivated to produce ‘tea tree oils’ and some P a g e | 1 others like Camellia japonica, Camellia sasanqua etc. are grown as ornamental plants (Benerjee, 1992). A free grown tea tree can reach a height of 30-40 feet if left un-pruned (Carr and Stephens, 1992). However, for the ease of harvesting young shoots they are either pruned or skiffed time to time to maintain a bed of reachable height.
