| Abstract | The contact and oral toxicity of fielddoses of selected pesticides against the cocoon andadult stages of a hymenopterous parasitoid Diadegma semiclausum were studied using severalbioassays. Field rates of ten pesticides wereselective to the parasitoid pupae. Fresh residue(s)of cartap, chlorfenapyr, emamectin benzoate andpermethrin were highly toxic, causing 100% mortalityof adult females in every treatment. Residual effectsof these four insecticides on cabbage foliage showedthat only cartap was highly persistent. Cartapresidues caused 100% mortality for over 30 d. In thesame assay three chitin synthesis inhibitors(chlorfluazuron, flufenoxuron and teflubenzuron) andone fungicide/bactericide (copper nonylphenolsulfonate) and two bactericides (kasugamycin andoxolinic acid) were nontoxic to adults. Effects ofcontact toxicity of chitin synthesis inhibitors andfungicides/bactericides on the untreated progeny oftreated parents was also determined: there was nosignificant difference in parasitism rates betweenprogeny of treated and untreated adults. When thefield doses of these chemicals were fed orally,mortality of female parasitoids ranged from 0% to17.23%. However, oral ingestion adversely affectedthe parasitism rate (p < 0.05) in alltreatments except oxolinic acid. Selectivity oftested pesticides against D. semiclausum andintegration of compatible pesticides with thisparasitoid for IPM of cabbage are discussed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
