How do you control the giant caterpillar on eucalyptus? Please explain.
The eucalyptus giant caterpillar can be controlled by referring to the following methods:
1. Manual capture: During the period when adults emerge in large numbers and lay eggs, promptly capture and kill the adults and egg masses in the orchard. During the larval damage period, the larvae generally rest quietly on the lower part of the host branches and trunk during the day, making them very easy to spot. Once larvae are seen at this time, deal with them immediately. When pruning in winter and spring, promptly cutting off the overwintering cocoons can also eliminate the overwintering pupae inside them.
2. Chemical control: In summer and after fruit harvest, in combination with the control of other pests, focus on spraying the leaf canopy with 90% trichlorfon 1000-1200 times dilution or 50% fenitrothion emulsifiable concentrate 1200-1500 times dilution.
