Abstract:
Dioryctria rubella Hampson is an important pest of the larger pine. It is widely distributed in China. There are two~three generatios a year in Nanjing. The larvae are borers which infest shoots of pines, and overwinter in the tunnels of dried shoots. The adult emerges from July to August the next year and lay its eggs in the needle of dried shoots. It is most active in the evening and responds positively toward a source of light. Both mating and ovipositing occur in the evening. The effective control measures for this pest are: Silvicultural measures including cutting off and clearing away the infested shoots. Natural enemies should also be protected and utilized;Tests results showed that the best chemical control was destroying adults by spraying with Fenitrothion;
