Abstract

Morphotypes of extrafloral nectarines were elevated at petioles, basal portion of leaf margins; paired, stalked button shaped in petioles, basal portion of leaf margins, smooth surfaced and bigger on petioles, smaller on leaf margins on Impatiens balsamina L. The number of EFNs were maximum and minimum at 36th and 42nd standard week in all the three varieties respectively. Population of Myrmicaria brunae was higher at 35th, 34th, 36th standard week. Population of Camponotus rufoglaucus J. were maximum at 36th standard week in variety 1 -purple and variety 2 - white and 35th standard week in variety 3 -purple with white. Population of M. brunae and C. rufoglaucus were lowest at 42nd standard week in all the three varieties. In I. balsamina, significantly positive correlation was observed between M. brunae, C. rufoglaucus and EFN numbers. Significantly positive correlation was also observed between M. brunae and C. rufoglaucus in variety 1,3 but were nonsignificant in variety.
