The subject matter of the booklet is extremely correct to the present emphasis on setting conservation, with specialize in local biodiversity conservation in agro-ecosystems. the present impetus being given to natural farming and export orientated agri-hortculture within the nation demands entry to suitable clinical wisdom base one of the stakeholders. learn on organic pest keep an eye on is greater than a century outdated in India. Egg parasitoids, that are commonly tiny wasps, led through the relatives Trichogrammatidae, are the main generally applied average enemies for organic keep an eye on globally. Over thirty nations are utilizing those bioagents to guard over 10 million hectares of agricultural and forestry vegetation from many very important insect pests. The publication includes 18 chapters, that are prepared in continuum, beginning with uncomplicated points of data and finishing of their usage ambitions. The chapters hide extensively 4 components: bio-diversity and typical incidence of egg parasitoids, behaviour and edition of egg parasitoids, mass construction and secure use of egg parasitoids and utilisation of egg parasitoids in numerous crop ecosystems. a few of the chapters cater to the wishes of discipline-wise replace at the present R&D scenario-like insect taxonomy, biotechnology, mass-production and quality controls of the objective organisms - egg-parasitoids, that are precious for laboratory scientists/researchers. There also are chapters dedicated to wisdom prestige and scope for usage of egg parasitoids in several objective vegetation, which cater to requisites of box entomologists and extensionists to be used of their initiatives of guiding farmers/local courses. The ebook is varied in technique, approach, constitution and content material and guarantees holistic insurance of the subject. The chapters are written via energetic and skilled employees in numerous plants and points and co-edited through 4 very skilled specialists who've over 3 a long time R&D event within the topic. all of the authors have uniformly focussed on finished literature research and demanding identity of information gaps for destiny R&D, therefore the booklet is novel in outlook, updated in content material and accomplished in assurance of issues. This publication could be necessary for supplementary analyzing for MSc Agriculture and PhD Agriculture scholars, in addition to MSc/PhD examine scholars in Zoology/Environmental Biology, who're specialising in Entomology. it is going to additionally function a truly beneficial reference e-book for researchers around the world, although concentration can be there on Indian paintings. It addresses the distinct details wishes of scholars and school, along with practitioners and extensionists within the Australasia and Africa areas and therefore now not constrained to the R&D wisdom generated in built countries.

Morphologically, the 11 species and a subspecies have been shown under two major groups (Nagaraja 1973a, b, 1978a, b; Nagarkatti and Nagaraja 1977) and four minor groups at r-0 level using numerical taxonomy and a dendrogram. In addition, Yousuf and Hassan (2006) described a new species from central India. The following characters were used for the taxonomic study (Nagaraja 1973a, b). Male Antenna (Fig. 1b) The male antenna has a five-segmented flagellum apart from two ring segments, two funicular and three club segments.
Nana under the ‘Specimens examined’ in the publication of description of the Indian species (Nagaraja 1978a, b). This mistake occurred due mainly to the earlier records in India of Tr. , Noctuidae) (Glover and Gupta 1939; Negi et al. 1945,1946), coconut leaf-eating caterpillars in Fiji (Tothill 1927) and slug caterpillar in Malaysia (Wood 1968) and many other references in Indonesia, Taiwan, etc. and hence the author construed this to be Tr. nana, since this was considered to be the most common oriental species elsewhere in Southeast Asia.
