Sisal elephant quarantine identification method
1 Scope
This standard applies to the quarantine and identification of sisal weevil.
2 Principle
Spread over long distances. Both sisal and larvae can cause damage to host plants. adults feed on host plant leaves and plant below the ground.
The leaf base or rot tissue of the object lays eggs, and the larvae after hatching enter the plant stems, which endangers the young tissues and growth points of the plants. The worm
Biological characteristics and their morphological characteristics are the basis for the development of this standard.
3 instruments, reagents
3.1 Biological microscope, stereo microscope, magnifying glass.
3.2 Hatchet, scissors, scalpel, anatomical needle, insect needle, scorpion, writing brush, flashlight.
3.3 Insect tanks, worm tanks, petri dishes, finger tubes.

Raised under 70% of the conditions, and observe whether there are adults.

The external morphological features of the worms (4.3 and 5.1) were observed under a stereo microscope.
5.3 Morphological characteristics
5.3.1 Eggs
It is 1.6mm to 1.75mm long and 0.7mm wide. It is long oval and milky white. The egg shell is smooth and thin.
