ANT CONTROLLERS AND METHOD FOR

APPLICATION THEREOF

BACKGROUND OF THE INVENTION FIELD OF THE INVENTION

The present invention relates to novel ant controller containing a hydrazine derivative as an active ingredient and to a method for application of the ant controller.

RELATED ART

The hydrazine derivatives represented by the formula (I) which can be used as active ingredient of the ant controllers of the present invention are known compounds disclosed in JP-A-5-4958, JP-A-5-17428, JP-A-5-32603, JP-A-5-262712, etc. In these patents, it is described that these derivatives have an insecticidal activity as agrihorticultuarl insecticides against

LEPIDOPTERA such as diamondback moth, rice leafroller, etc., HEMIPTERA such as tea green leafhopper, pear lace bug, etc., COLEOPTERA such as twenty-eight-spotted ladybird, maize weevil, etc., DIPTERA such as melon fly, house fly, house mosquito, etc., and TYLENCHIDA such as coffee root-lesion nematode, root-knot nematode, etc.

Any of these patent gazettes, however, does neither describe nor suggest that said hydrazine

derivatives have a marked insecticidal effect against ISOPTERA such as formosan subterranean termite, kolbe, etc., HYMENOPTERA such as cabbage sawfly, Carpenter ant, etc., ORTHOPTERA such as Japanese cockroach, field cricket, rice grasshopper, etc., and PSOCOPTERA such as large pale booklouse, etc.

SUMMARY OF THE INVENTION

The present inventors have conducted extensive studies with the aim of creating a novel ant controller having a marked controlling effect upon ants doing harm to the wooden materials constituting houses, furniture, etc. or crops and human being. As a result, it has been found that some of the hydrazine derivatives described in the above-mentioned prior art have a marked

insecticidal effect upon termites and ants. The present invention has been accomplished on the basis of this findings.

inoculated with Coptotermes formosanus Shiraki. Seven days after the inoculation, percentage of dead insects was investigated, from which mortality was calculated. The results were evaluated according to the following criterion. The test was carried out with triplicate group of 10 insects.


The results are summarized in Table 6.

Test Example 2

The ant controller of the present invention was applied to nests (anthill) of fireant (Solenopsis geminata) with drench treatment, in terms of 1 g of the active ingredient per one nest. 14 Days after the treatment of the ant controller, the activity of the nests was evaluated according to the following

criterion. The test was carried out with one block per one nest.
