| Abstract: |
Rhynchocoris Jwmeralis Thunberg (Citrus green stink bug: CGSB) is one of the important
insect pests of mandarin in the westem hills of Nepal, that causes premature fruit drop in
mandarin, resulting heavy loss in fruit yield. This study aims to manage it through integrated
approach, which comprises of its field life cycle and behavior. This study was carried at
Hemja (1060 mas 1.) and Lrmrfe (1675 mas l.) during June to December 2001 and 2002.
Freshly hatched nymphs were inoculated in sleeve cage that was confined to a branch having
2-3 small fruits. Observations were made to record incubation period of egg, duration of each
nymphal instar and number of dropped fruits at each instar. This study revealed that the pest
had five nymphal stages prior to emerge as an adult. The first instar stmted feeding on the
fruit that induced fruit drop. The adult of CGSB remained alive for more than 50 days in the
winter to build population for the next season. |
