| Abstract | Two field experiments were conducted in Hawaii to determine the responses of lepidopteran pests and their associated natural enemies to broccoli (Brassica oleracea), grown in monoculture or interplanted with chili pepper (Capsicum annuum), or yellow sweetclover (YSC) (Melilotus officinalis). The population responses of Artogeia rapae and Trichoplusia ni to habitat types were not consistent during the field trials. Additionally, their reactions to habitat diversification differed according to non-host plant species. For example, Trichoplusia ni densities were significantly lower in the broccoli–YSC habitat contrasted with the broccoli–pepper habitat on most sampling dates. Similarly, the proportion of plants damaged by Hellula undalis was significantly lower in the broccoli–YSC habitat contrasted with broccoli–pepper habitat. Findings from the study, suggest that biological control agents (e.g., spiders, parasitoids, and␣entomopathogens) are the most significant factors influencing the abundance of A.␣rapae in habitat type and that these agents inflict greater mortality on A. rapae in diculture than monoculture habitats. |

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.
