Three new species of parasitic wasps (Braconidae: Microgastrinae) from southern India are described and illustrated. Glyptapanteles clanisae sp. nov., a remarkable gregarious endoparasitoid, was bred from the caterpillar of Clanis phalaris Cramer (Lepidoptera: Sphingidae) on the host plant Pongamia pinnata (L.) (Leguminosae) along with a hyperparasitoid, Eurytoma sp. (Eurytomidae). Glyptapantel...

Studies that rigorously measure the effectiveness of anti-predator traits in complex ecological communities are rare. Rarer still are studies that compile the results of these trait analyses in a framework that explains the variation in predation pressure by a predator assemblage. Here the risk of predation by ants is quantified for a community of caterpillar species that employ several putativ...

This demonstration introduces Caterpillar, an open-source Business Process Management System (BPMS) that runs on top of the Ethereum blockchain. Like any BPMS, Caterpillar supports the creation of instances of a process model (captured in the Business Process Model and Notation – BPMN) and allows users to track the state of process instances and to execute tasks thereof. The specificity of Cate...

We study caterpillar tree automata [3] that are restricted to enter any subtree at most one time (or k times). We show that, somewhat surprisingly, the deterministic one-visit automata can already, for instance, evaluate trees where the nodes represent some non-associative operations. We show that there exist regular tree languages that cannot be accepted by a one-visit automaton, thus proving ...

A graph G of order n is called arbitrarily vertex decomposable if for each sequence (a1, . . . , ak) of positive integers such that a1+. . .+ak = n there exists a partition (V1, . . . , Vk) of the vertex set of G such that for each i ∈ {1, . . . , k}, Vi induces a connected subgraph of G on ai vertices. D. Barth and H. Fournier showed that if a tree T is arbitrarily vertex decomposable, then T ...

Bacillus thuringiensis (Bt) synthesizes crystalline inclusions that are toxic to caterpillars (Lepidoptera) and other orders of invertebrates. Materials associated with 37 caterpillars from 16 species, collected while feeding on 15 different species of host plants in dry, cloud and rain forests located in the Area de Conservación Guanacaste in northwestern Costa Rica, were examined for the pres...

Alternative ways to control caterpillar pests and reduce the use of pesticides in apple orchards are in the interest of the environment, farmers and the public. Great tits have already been shown to reduce damage under high caterpillar density when breeding in nest boxes in an experimental apple orchard. We tested whether this reduction also occurs under practical conditions of Integrated Pest ...

A general field bioassay for detecting biologically active compounds in plants and insects has been developed and tested for efficacy and sensitivity. Methanolic extracts, in sucrose solution, of 20 plant and six caterpillar species were offered to the ponerine ant Paraponera clavata and the feeding preferences observed. The bioassay resulted in the detection of nine plant and three caterpillar...
