surviving canopy of the chestnut tree,The imagoes and the larvae reach the peak ofdamage
from mid July to mid August.In a control test against this pest ,five pesticides wereapplied.
Comparatively,two of them proved good and effective , which are 40%oxidized Rogorwith 2000
times of diluent and 95%dipterex with l000 times of diluent. |
