Abstract

A simple and efficient breeding method for the bagworm moth is provided, as well as a device for performing the method. Also developed and provided is a method of easily collecting eggs from a bagworm moth, an egg collection device for bagworm moths composed of a tubular container. A bagworm moth breeding method and egg collection method performed using the device are also described.

First claim

The invention claimed is:

1. A bagworm moth egg collection device composed of a tubular container, comprising:
an insert hole having an inner diameter into which a female adult of a bagworm moth fits whereby the female adult, bagworm moth is fixed to the bagworm moth egg collection device;
a receiving part capable of receiving the abdomen of the female adult; and
an egg-holding part configured to hold eggs obtained by egg-laying.

2. The egg collection device according to claim 1 , wherein the egg-holding part has a ventilating means.

3. The egg collection device according to claim 1 , wherein the egg-holding part has, therein, a removable egg-receiving means for receiving and collecting the egg obtained by egg-laying.

4. The egg collection device according to claim 1 , further comprising a lid configured to occlude the insert hole.

5. The egg collection device according to claim 1 , wherein the whole or part of the tubular container comprises a transparent material or a translucent material.

6. The egg collection device according to claim 3 , wherein the egg-receiving means consists of a thin-layer film composed of a transparent material or a translucent material.

7. The egg collection device according to claim 1 , further comprising an egg-collecting stand configured such that the egg collection device is placed in the egg-collecting stand in such a manner that the insert hole faces upward.

8. A bagworm moth breeding method, comprising:
inserting the bottom of the abdomen of a female adult of a bagworm moth into an insert hole of the egg collection device for bagworm moth according to claim 1 to fit the abdomen into the insert hole; and
inserting the bottom of the abdomen of a male adult of a bagworm moth between the insert hole and the abdomen of the female adult to induce mating.

9. The breeding method according to claim 8 , wherein the female adult of the bagworm moth is an apterous and apodous morphospecies.

10. The breeding method according to claim 8 , wherein the female adult is a virgin.

11. A bagworm moth egg collection method, comprising:
inserting the bottom of the abdomen of a female adult of a bagworm moth separated from a nest and a puparium into an insert hole of the egg collection device according to claim 1 to fit the abdomen into the insert hole;
inserting the bottom of the abdomen of a male adult of a bagworm moth between the insert hole and the abdomen of the female adult to induce mating; and
allowing the female adult to lay eggs in the egg-holding part of the egg collection device.

12. The egg collection method according to claim 11 , further comprising removing the female individual after the egg-laying process.

13. A method of producing a first instar bagworm, comprising:
incubating, in the egg-holding part, the bagworm moth egg obtained by the egg collection method according to claim 11 ; and
collecting a hatched first instar bagworm.

14. A method of producing a first instar bagworm, comprising:
collecting, from the egg-holding part, the bagworm moth egg obtained by the egg collection method according to claim 11 ; and
incubating the egg collected.
