One of the diseases that can be transmitted by flies is diarrhea. Green betel leaf contains essential oils, chavicol, arecoline, phenol, and tannins which function as plant-based insecticides. This study aimed to determine the effectiveness of green betel leaf extract (Piper betel) as a plant-based insecticide on the number of mortality of house flies (Musca domestica). The research was an experimental study used After Only Design used the One Way Anova test with a 95% confidence level. The samples used were 360 ​​house flies. Each treatment of 30 house flies with 4 repetitions and used three concentrations of green betel leaf extract (25%, 50%, 75%). The study was conducted at the Chemistry and Microbiology Laboratory of Health Polytechnic Tanjungpinang, while the location of the fly collection was at the Tokojo Garbage Collection Station in Bintan Regency. The number of mortality of house flies at a concentration of 25% was 81 heads (67.5%), 50% concentrations were 93 heads (77.5%), and at a concentration of 75% were 103 heads (85.83%). There was an effect of green betel leaf extract on the mortality of house flies (p-value 0.0001 <0.05) with the most effective concentration of 75%. Further research is needed to obtain a finished product utilizing green betel leaf extract as a vegetable insecticide, especially in controlling the fly vector. Need further research on the use of green betel leaf extract as a vegetable insecticide controlling the fly vector by taking into account the amount of spraying and the age of the fly.   Keywords: Green betel leaf extract , organic insecticide, houseflies

The control of houseflies (Musca domestica L.) in veterinary surveillance premises is an important measure for the welfare of animals against infectious and invasive diseases. For this purpose, the most effective chemical insecticides are used. To prevent possible resistance to them, bait insecticides with two active binary ingredients from different chemical classes are used. The work was carried out in the laboratory of the Tyumen Scientific Center and in the production conditions of ZAO Pyshminskaya Poultry Farm. This material presents the main stages in the development of a prototype of the insecticidal bait Mukhnet AX containing two insecticides: 1.5% acetamiprid and 6% chlorfenapir. For this purpose, adults of houseflies Musca domestica L. 3-5 days old were used. Under laboratory conditions, effective rational doses of the above insecticides were determined by group feeding, feeding and by the method of assessing food insecticidal baits when fighting flies from 0.00002 to 4% concentrations. According to the results of laboratory studies, it was found that the optimal doses causing 100% death of insects were 0.5% for acetamiprid and 2% for chlorfenapir. The insecticidal efficiency of the developed bait Mukhnet AH against flies in production conditions on the first day after the treatment of the livestock building was 91.25%. The insecticidal effect of the measures taken lasted for at least 6 days. The restoration of the number to the previous level of the number of insects occurred after 10 days. Based on the results obtained, the Method of using the composition of an insecticidal bait agent in the fight against Musca domestica was proposed and patented.

In Musca domestica, the primary signal for sex determination is the dominant factor M, which is assumed to regulate a postulated female-determining gene F. Presence of M prevents expression of F so that male development ensues. In the absence of M, F can become active, which dictates the female pathway. The existence of F is inferred from FD, a dominant factor that is epistatic to M. We describe a new mutation masculinizer, which has all the properties expected for a null or strongly hypomorphic allele of F: (1) it maps to the same chromosomal location as FD, (2) homozygous man/man animals develop as males, (3) homozygous man/man clones generated in man/+ female larvae differentiate male structures, (4) man has a sex-determining maternal effect. About a third of the morphological males synthesize yolk proteins, which indicates that they are intersexual in internal structures. The maternal effect of man is complete in offspring that derive from homozygous man/man pole cells transplanted into female hosts. In this case, all man/+ progeny become fertile males that do not produce yolk proteins. A sex-determining maternal effect has previously been demonstrated for FD. Like F, maternal man  + is needed for zygotic man  + to become active, providing further evidence that man is a loss-of-function allele of F.
