Biological Test Example 6 0161 Peroral Acute Toxicity for Mouse 0162 Each of the present compounds was suspended in a 0.5% aqueous carboxymethylcellulose solution to obtain a suspension of a predetermined concentration. Male SIc:ICR mice (SPF) of 6 weeks old (body weight: 29.5 to 34.4 g) were fasted for 3 hours. 1 ml, per 100 g of the body weight, of the suspension was forcibly fed into the stomach of each mouse. Then, a food and water were given to the mice and they were bred in a cage. The observation period after the administration was 7 days. During that period, the life and death, general conditions and change in body weight of the mice were observed. Thereafter, pathologico-anatomic experiments were carried out (two mice in each-group). 0163 When 300 mg/kg of Compound No. 1-5 was used, the results were as follows: Neither death nor abnormality of the general conditions was recognized, the body weight of the rat increased normally, and no abnormality was found in the dissection view after the completion of the observation. 0164 It is thus understood that the compounds of the present invention have an insecticidal activity superior to that of publicly known hydrazine oxoacetamide-related compounds particularly at a low concentration and that these compounds have a high safety on animals. 0165 The present application is a continuation of PCT application JP 99-05760 filed Oct. 19, 1999, upon which priority is requested based on 35 USC 120, based on Japanese application Serial Number 10-297240 filed Oct. 19, 1998 upon which priority is requested based on 35 USC 119. 0166 Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
