| Abstract | The behavior of the neonate larvae of the western corn rootworm (WCR) Diabrotica virgifera virgifera LeConte, a major pest of maize, was assessed in the presence of maize roots constitutively emitting (E)-β-caryophyllene (EβC). This root volatile has been shown to attract both second instar WCR and insect-killing nematodes, and may offer innovative alternatives in helping to manage WCR. Under greenhouse conditions, the maize inbred line HiII, lacking the ability to emit EβC, was planted 75 cm from the maize inbred line 201-L1, the HiII inbred genetically engineered to constitutively emit EβC. WCR eggs were infested in the center of the two lines and neonate attraction toward either root system was recorded after collecting WCR larvae established on the plants. Whereas marginally more larvae were found on EβC-emitting plants, counts of recovered WCR neonates did not significantly differ between the two lines. This supports the postulate that CO2 is the primary attractant for WCR neonate larvae. The chemical ecology of WCR larvae is discussed. A conceptual model of the foraging behavior of this pest is proposed, summarizing our current knowledge on chemically mediated interactions between WCR larvae and maize roots. |

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.
