| Abstract | Females of Parastrachia japonensis (Hemiptera: Cydnidae) provision nymph-containing nests with drupes of the single host tree, Schoepfia jasminodora (Rosidae: Santales). P. japonensis feeds on the endosperm of these drupes. Foraging females approached and accepted only a few selected drupes for transport to their nests from among the hundreds of drupes scattered on the ground. The characteristics of the drupes that elicited an acceptance response under field conditions were examined. Females estimated the degree of endosperm development using volatile and nonvolatile chemicals in the outer skin as cues and selected only those drupes which had a well-developed endosperm. Although the cues that prompted approach and inspection of a drupe are in the fleshy outer skin, females presented with various substitute drupes coated with outer skin juices of acceptable drupes selected only those they could recognize as a solid mass, suggesting that they used volatile chemicals in the outer skin as cues for approaching and inspecting a drupe and then taste and tactile stimuli as cues for acceptance. Thus, this bug possesses a complex, ecologically sensitive cognitive system that enables it to recognize valuable food items by using reliable cues. The importance of selective foraging by P. japonensis females and the evolutionary significance of this behavior 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.
