DESCRIPTION:
BRIEF SUMMARY
The present invention relates to compositions for attracting flies to capture and kill them. The invention also relates to attracting-insecticidal compositions for attracting and killing flies and to attractant-bait compositions for poisoning flies by attracting the flies and inducing them to ingest the composition.
Unexamined Japanese Patent Publication SHO No. 56-115706 discloses that flies are attracted to yellow-colored substances having a hue of 5YR to 7.5GY according to the standard prescribed in JIS Z 8721. However, the attracting effect of the yellow-colored substances of this hue on flies is insufficient and in no way satisfactory.
On the other hand, it is also known that 9-tricosene, cis-9-tricosene, etc. have a fly attracting effect as sex pheromones of flies. Nevertheless, the attracting effect of these sex pheromones is also insufficient, so that the fly controlling agents incorporating these pheromones as attractants are still low in controlling efficiency.
The present invention provides a fly attracting composition having an exceedingly higher attracting effect on flies than is achievable by the prior art mentioned.
The invention further provides an attracting-insecticidal composition for attracting flies very effectively and controlling them.
The invention further provides an attractant-bait composition for attracting flies very effectively and causing them to be attracted to the bait with enhanced tenacity so that the insecticidal component thereof can be taken into the body in an increased amount to completely control the flies.
These and other objects of the present invention will become apparent from the following description.
The fly attracting composition of the present invention is characterized by: selected from the group consisting of 9-tricosene, cis-9-tricosene, 10-methyl-9-tricosene, cis-2-methyl-8-docosene, cis-9-docosene, cis-8-docosene and cis-10-tricosene, mean grain size.
The fly attracting compound to be used in the present invention is known as a sex pheromone of flies having a fly attracting effect, but the effect is low, whereas our research has revealed that when the preparation containing the compound has a yellowish red color in the range of 2.5R to 2.5YR in hue and is in the form of grains having a mean size in the specific range of about 0.5 to about 5 mm, the preparation unexpectedly exhibits a surprisingly high attracting effect on flies. The high fly attracting effect is available only when the attracting compound, hue and form of the preparation are as specified above in combination. Such a remarkable attracting effect can not be obtained if other attracting compounds are used, or if the hue of the preparation is outside the specified range of 2.5R to 2.5YR, or if the preparation is not granular or is outside the above range in grain size even when granular.
The attracting compound to be used for the present invention is a sex pheromone selected from among 9-tricosene, cis-9-tricosene, 10-methyl-9-tricosene, cis-2-methyl-8-docosene, cis-9-docosene, cis-8-docosene and cis-10-tricosene. Among these, cis-9-tricosene is especially preferable. According to the present invention at least one of these compounds is used. The concentration of the attracting compound in the preparation is usually about 0.01 to about 15 wt. %, preferably about 0.02 to 4 wt. %, although widely variable.
It is essential that the fly attracting composition of the present invention exhibit a yellowish red color in the range of 2.5R to 2.5YR in hue according to the standard prescribed in JIS Z 8721. If the hue has a closer resemblance to red off 2.5R or to yellow off 2.5YR, the contemplated high fly attracting effect is not available. More preferably, the hue is in the range of 7.5R to 2.5YR. It is also desirable that the present preparation having the above-specified hue be at least 4, more preferably at least 5, in lightness and at least 6, more preferably at least 7, in saturation according to JIS Z 8721.
