The present invention pertains to a poison bait for control of noxious insects.
There have heretofore been commercially available some powdery posion baits for exterminating noxious insects such as cockroaches. These conventional poison baits in a powdery form are, however, practically disadvantageous and dangerous in causing many problems fro m the standpoints of sanitary and daily usages. For instance, they attach to the hands on handling, fly about the surroundings after being situated in desired places or are apt to be erroneously taken as food by infants and household pets.
In order to solve the above problems, a poison bait in a tablet form was put into the market, which comprises boric acid as the active ingredient. For assurance of the eradicating effect, however, such poison bait tablets should contain boric acid in such a large amount as about 20 to about 30 by weight. Because of this reason, they are still not safe for infants and household pets. In fact, it is reported that even a baby powder containing boric acid in an a~nount of only 5 by weight accidentally produced the death of an infant (11th Japan Pharmacopoeia Commentary, C-1475 (1986)). In addition, the bait containing boric acid makes cockroaches suffer from diarrhea and produce soft excrements, so that their habitats and -2- 2 surroundings are considerably stained thereby.
There are also known some poison baits in tablets, which comprise as the active ingredient an insecticide chosen from organic phosphorus insecticides, and carbamate insecticides, etc. However, said insecticides have each a characteristic odor, and a tablet preparation comprising the same is apt to be repelled by cockroaches. Thus, the feeding attractant effect is much inferior, and naturally the eradicating effect is lowered. Further, these insecti- *cides easily hydrolyze even with a slightest amount of water to produce a certain specific odor, thereby the feeding attractant effect is deteriorated and the eradicating effect S is decreased. Said hydrolysis results in lowering of the content of the active ingredient itself, and the insecticidal effect is thus remarkably deteriorated.
A proposal was made to provide a poison bait ocomposition in a tablet form which comprises at least one insect-growth controlling agent chosen from insect juvenile hormone-like compounds and insect chitin-synthesis inhibitors, and crystalline cellulose (JP-A-01-143806). However, incorporation of feeding attractant having an excellent effect such as animal powders and crushed biscuit into said composition tends to cause cracking of the resultant tablet, and tabletting is made impossible unless the feeding attractant is used in a finely pulverized state. Due to the above reason, the feeding attractant as usable is restricted -3to starches or sugars, and therefore the effect is not satisfactory.
There has thus been a great demand for a poison bait having a high safety to human beings as well as domestic animals, a remarkable feeding attractant effect and a sufficient insecticidal effect in addition to the safety on handling and the stability of the active ingredient.
As a result of the extensive study, it has now been found that a tabletted poison bait composition comprising a certain specific insect-growth controlling agent in combination with some certain additives meet the above demand.
.e According to this Invention, there is provided a 15 poison bait composition in a tablet form, which comprises as the essential components at least one insectgrowth controlling agent chosen from insect juvenile hormone-like compounds and insect chitinsynthesis inhibitors, dextrin and a plant oil in an amount of not more than 10% by weight to the total bait composition, optionally with at least one feeding attractant selected from sugars in an amount of not more than 60% by weight, cereal flours in an amount of not more than 50% by weight, (d-3) o 25 crushed biscuit in an amount of not more than 50% by weight and animal powders selected from fish powders, chrysalis powders, Euphauciasea powders and shrimp powders in an amount of not more than 10% by weight to the total bait composition.
The bait composition comprising the above compo- 911107,dbdat.091,55884.res,3 i 4 nents can be stably formulated into a tablet and exerts a sufficient eradicating effect against harmful insects. The composition is also effective in inhibiting emergence of insects as well as reducing reproductivitiy. Further, incorporation of sugars, cereal flours, crushed biscuit and/or animal powders as the additional components enhance the feeding attractant effect and the stability of the essential components.
As the component there are exemplified dodecadienoate compounds, oxim ether compounds, pyridyl ether compounds, carbamate compounds, etc., of which representative compounds are shown in Table 1: Table 1

For preparation of the poison bait composition of the invention, the essential and optional components as above mentioned may be mixed together to make a uniform mixture, which is then subjected to tabletting by a per se conventional procedure. For instance, one or more insectgrowth contolling agents are mixed with dextrin, plant oil and a feeding attractant to make a uniform mixture, which is then tabletted by a per se conventional procedure to give a bait composition in a tablet of desired size normally under a pressure of about 10 to about 500 kg/cm 2 The thus obtained bait composition exerts a remarkable insecticidal effect against a wide range of harmful insects, of which examples are cockroaches (Blattidae) such as American cockroach (Periplaneta americana), German cockroach (Blattella germanica) and smokybrown cockroach (Periplaneta fuliginosa, ants (Formicidae) such as Monomorium sp. and Formica japonica, deathwatch and drugstore beetles (Anobiidae) such as cigarette beete (Lasioderma serricorne) and biscuit beetle (Stegobium paniceum), darkling beetles (Tenebrionidae) such as red flour beetle (Tribolium castaneum) and confused flour beetle (Tribolium confusum) and cucujid beetles (Cucujidae) -9such as saw-toothed grain beetle (Oryzaephilus surinamensis) and flat grain beetle (Cryprolestes pusillus), termites (Isoptera) such as Formosan subterranean termite (Coptotermes formosanus) and Reticulitermes speratus, etc.
Practical embodiments for preparation of the insecticidal composition according to the invention are illustratively shown in the following Examples wherein are by weight unless otherwise indicated.
SExamples 1 to 6 Pyriproxyfen (0.05 dextrin (96.85 in Example 1; 30.0 in Examples 2 to 6) and dehydroacetic acid (0.1 were mixed together, and an essential oil, sugar, cereal flours, crushed biscuit and animal powders as shown in Table 3 were incorporated therein, followed by mixing uniformly.
The resultant mixture was tableted under a compression of kg/cm 2 to make tablets, each weighing about 4 g (diameter, about 30 mm).
The thus obtained tablets as a bait were subjected to evaluation of the tablettability, stability of the active ingredient, the feeding attractant effect, the inhibitory go effect on emergence and the inhibitory effect on reproduction according to the following procedures, and the results are shown in Table 3: 1) Tabletability:- Observation was made immediately after the tableting under a compression of 15 kg/cm 2 and also after -a-II 10 days storage at 50 0 C, and the tabletability of a tablet of about 4 g (diameter, 30 mm) was evaluated with respect to production of cracking: no crack; cracks.
2) Stability of the active ingredient:- The bait in a tablet form was kept at 50 0 C for days and subjected to measurement of the residual percent of the active ingredient by gas chromatography. Evaluation was rade on the following criteria: Criteria Residual active ingredient 80 70 80 S. 70 3) Feeding attractant effect effect attracting and stimulating the insects to eat food):- Fifty imagos of Blattella germanica (even numbers in male and female) were admitted in a container having a bottom area of 0.12 m 2 where the bait in a tablet form as well as a solid bait as control were placed. An attractant rate was calculated on the basis of the numbers of the insect being attracted by the bait within a designated period and classified on the following criteria: Criteria Attractant rate 80 70 80 <70 4) Inhibitory effect on emergence:- Ten last instar larvae of Blattella germanica (even numbers in male and female) were admitted a 11 container having bottom area 100 cm 2 where the bait tablet form as well solid control placed, observation was made failure emergence, abnormality wings supernumerary molting over period three weeks. The number counted to calculate emergence inhibitory rate results are classified following criteria: Criteria Emergence 80 70 5) reproduction:- comparison hatched eggs observed four weeks.
