| Abstract | Predation by Achaearanea tepidariorum (Koch 1841) on mealybugs Planococcus citri (Risso 1813) is facilitated by the design of its web, which features a tangle of sticky gumfooted lines, and wrap attacks as well as the ability to handle the prey, whose body is covered with a waxy secretion, via silk. Crawling, i.e., wingless, mealybugs (in particular those in the nymphal stages and adult females and, to a lesser extent, winged males) are caught by means of the gumfooted lines, covered with globules of an adhesive secretion. The process of wrap attack and subsequent handling of the captured prey is a series of the following consecutive events: (1) confining and immobilising the mealybugs with sticky silk; (2) biting with chelicerae and paralyzing the prey with a toxin; (3) detaching the confined prey, attached to the tense threads, from the plant surface and catapulting it toward the central section of the web; (4) wrapping the catapulted prey in viscid silk emitted by the spinning apparatus; (5) transporting the wrapped prey to the central section of the web; (6) wrapping the prey in the central section of the web in nonsticky silk, whose tufts are present in this part of the web even before the attack; (7) filling the prey with digestive fluid; (8) sucking the prey empty; and (9) cleaning the chelicerae and mouth parts. The process of silk tuft wrapping was described for the first time. The described ability to hunt mealybugs implies the possibility of using A. tepidariorum spiders for biological control of these pests. |

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.
