6.1 Detection of Palmae Seedlings
When selecting points to observe the leaves, look at them from bottom to top, especially the old leaves in the lower part. Pay special attention to it first to see if there are adult insects on the leaf surface, and then
Observe that each leaflet has an ovoid sac-like bulge of 2mm to 3mm, find the cysts, and cut the whole leaf. Put the leaf in the sample bag, and the adult
Use finger tubes to hold larvae or pupae with 8% formalin vacuole and bring them back to the room for further inspection.
6.2 Detection of coconut fruit and coconut shell fiber
When selecting points for inspection, first observe whether the outer package has worms, then open the package, observe them fruit by fruit, pay attention to the pedicles or cracks that can conceal the insects, and
Invert the bag to see the debris at the bottom of the bag. Samples of coconut fruit or coconut shell fibers with suspected worms may be taken for further laboratory inspections, and pay attention to
Inspection of loading containers or loading containers.
6.3 Feeding
The immature worms, such as the pupa, larvae, and pupae of the coconut pupa, which need to be raised, together with the relevant parts of the host, should be at a temperature of 25 ℃ ～ 30 ℃
Humidity was observed at 70%, and identification was performed after emergence of adults.
7 Laboratory identification
7.1 Preparation
The surface of the insect body used for observation must be clean. If there is dirt or dust on the body surface, the specimen should be immersed in 70% ethanol and washed with a brush.

Appendix A
(Informative appendix)
Coconut Wing Breast Leaf Methyl
A. 1 host
Coconut, yata coconut, oil palm, king palm, betel palm, thorn sunflower and sago coconut.
A. 2 Geographical distribution
Distributed in Malaysia, Singapore, Brunei, Philippines, Indonesia, Sri Lanka.
A. 3 Harm
Adults feed on the leaves; larvae enter from the surface and eat on the leaves. Each larva eats food towards the leaf end throughout its life, leaving only the sacral part
Upper surface, and quickly dry brown. There are often multiple worms on the leaves that harm simultaneously. The victim leaves are curled, scorched, and easily broken by wind. Much more
This fungus invades and produces silver-gray fruiting bodies. When seriously injured, the adult and larva together can reduce the photosynthetic leaf area by 75%, so that the fruit falls,
Yield loss can reach 80%; the tree crown is brownish gray when viewed from a height, and the landscape is greatly affected.
A. 4 Biological characteristics
Adults often endanger older leaves (ie, fourth to fifth leaves) of the lower part of the plant, but when the damage is severe, the young leaves are also damaged. Adults first
A small hole is bitten on the back of the leaf to lay a single egg. Then, the feces are covered and the glue is secreted to form an oval with a length of about 2mm to 3mm.
Capsule-shaped bulging. The newly hatched larvae drilled directly into the leaf and ate towards the end of the leaf, forming a pupal with a width of about 1 cm and a length of 10 to 20 cm.
Road, emptying the mesophyll leaves only the epidermis, the surface is bubbly. Old mature larvae pupate in the tunnel.
