Abstract

This paper covers detailed investigations on the aphid-fauna associated with forest trees of Kashmir Valley, together with their hymenopteran parasites as natural enemies of various aphid species. A total of 29 spicies under 23 genera of aphids have been found to damage 24 species of forest trees and 21 species distributed over 10 genera of aphid parasitoids are reported to occur in this region. Host plant, aphid and parasitoid list is also added.

Abstract

The present communication deals with aphid pests, damaging forest trees in diverse areas and localities in Jammu Kashmir and Ladakh region of north-west Himalaya. Updated information pertaining to systematic checklist, host-range and species richness of 51 aphid species, under 26 genera, belonging to 10 different sub-families of family Aphididae, damaging 34 forest-tree species, distributed over 17 genera of 10 families, have been provided. Salixs and poplars (Salicaceae), are found infested with highest number of aphid species as 23. The dominant aphid species attacking forest trees in different areas pertained to the sub-family Erisomatinae as 15 and aphid genera viz. Chaitophorus and Pemphigus incorporated highest number of species as 6 each. A catalogue on host-tree (forest) complex of aphids of Jammu, Kashmir and Ladakh region, has been presented.

Abstract

The present paper deals with the termite-fauna of Jammu, Kashmir and Ladakh Himalayan region. An updated annotated systematic checklist of 23 species of termites, belonging to 9 genera, under 3 major families and 6 subfamilies, occurring in vast areas/localities in diverse habitats of these regions, has been provided. Family Termitidae is the dominant component of termite-fauna (86.96 %) and most species rich genus is Odontotermes (52.18%) of total species, in this part of north-west Himalaya. The major termite pests of these Himalayan regions are: Angulitermes tilaki, Microtermes obesi, Odontotermes canidia, Odontotermes obesus and Trinervitermes biformis. These cause damage to agricultural crops (food, vegetables, fodder / grasses), forest trees and wood-building structures. Faunal distribution and biodiversity of termite species, have also been briefly discussed.
