Control of the Mupli Beetle, Luprops tristis (Coleoptera: Tenebrionidae), and Dormancy Phase-related Variation in Insecticide Susceptibility1

Abstract: Massive home invasions by the Mupli beetle, Luprops tristis F. (Coleoptera: Tenebrionidae), with the onset of monsoon rains, aggregation in a prolonged state of dormancy at specific locations, and repeated selection of the same locations for years provides an excellent opportunity to control the beetles employing suitable insecticides. The weak physical stature of the surviving beetles during the last phase of dormancy lead to the proposition that there were differences in insecticide susceptibility during the early- and late-dormancy phases. Hence, efficacy of three pyrethroid insecticides were tested with filter-paper bioassays to determine LC99 and KC99 values in the early and late phases of dormancy and to analyse whether the efficacy of the compounds vary between the early and late phases. During the late-dormancy phase, these compounds caused immediate knockdown but not immediate mortality at the lowest application rates. However, because the beetles have to be controlled during the early p...

Darkling beetles (Coleoptera: Tenebrionidae) of forest sites and agricultural fields in the south Western Ghats (South India)

Abstract: Data on the abundance, feeding guilds, flightlessness and endemic status of darkling beetles from selected forest sites and agriculture fields in the moist south Western Ghats in south India are provided. Overall abundance, diversity and evenness were higher in agriculture fields than in forest. Luprops tristis was the major species in agriculture field and Gonocephalum bilineatum in forest. Mycetophagous and detritivorous guilds were reported from the agriculture fields and detritivorous guild alone from the forests. Epigean, subterranean, corticolous, dung associated and mycetophagous darkling beetles were present in agriculture fields in contrast to the record of epigean and subterranean forms in forests. Higher abundance of flightless platynotine genus Menearchus, endemic to the Indian subcontinent in the agricultural field is attributed to the decaying organic matter availability in the open, dry environment conditions in agriculture field.

Taxonomy of Euschizomerus Chaudoir 1850 (Coleoptera: Carabidae: Panagaeinae) from India with a new species and new synonym.

Abstract: Description of new species Euschizomerus devagiriensis sp. nov. from south India, synonymisation of Euschizomerus schuhi Kirschenhofer, 2000 with E. indicus Jedlicka, 1955, redescriptions and new records of the earlier reported Indian species with a key to the species are provided.

Two new species of Tripogon (Poaceae: Chloridoideae: Tripogoninae): from India

Abstract: Two new species of Poaceae, Tripogon karnatakensis and T. munnarensis from South India are described and illustrated. T. karnatakensis closely resembles T. filiformis , but differs in having 15–28 cm long leaden green spikes with 2-keeled lower glumes. T. munnarensis closely resembles T. narayanae , but differs in having 10–16 mm long spikelets with 10–16 florets.
