| 總結: | Harumanis mango in Perl is suffered from the outbreak
of leaf hoppers, Idioscopus nitidulus Walk. in 1986 and
1987. The laboratory and field experiments were conducted to investigate some aspects of the biology of mango
leafhoppers, initidulus Walk. an important pest of
mango flowers and shoots in south East Asia. The synchrony of insect population with the phenology of the
plant was also studied.
The adults were found to survive on mature leaves
in the absence of flowers and shoots. However, reproduction occurred during the onset of flowering and young
shoot development.
The fluctuating patterns in the abundance of hoppers
coincided with the availability of flower panicles and
developing shoots. The number of hoppers appeared unaffected
by the heights and positions of flower panicles
in the tree. |
