Chronic Use

The housefly, Musca domestica, L. (Diptera: Muscidae) is a genuine danger to human and creature wellbeing. Houseflies are vectors of in excess of 100 human and creature intestinal maladies. They are fit for communicating parasites that cause illnesses, for example, typhoid fever, cholera, bacillary looseness of the bowels, juvenile the runs, tuberculosis, plague, sickness, yaws, samonellosis, trachoma, and Bacillus anthracis. Creature wellbeing concerns incorporate the transmission of pinkeye. If we want to quell this insect pest the humans using insecticides and repellents but due to chronic use of these chemical compounds will create insecticide resistance in these domestic insect pests. There are numerous proteins/enzymes responsible for degradation of the chemicals used to get rid of these pests, but due to the action of some of the proteins/enzymes namely Ache gene(considering in the current study) will be rigorously involved in degradation of chemical compounds results in expressing the resistance in Houseflies. With the application of network biology the current study dealt efficiently in understanding how the interacting/supporting mechanism helps in expressing the resistance mechanism. With the help of STRING DATABASE in data collection and CYTOSCAPE-3.0 in visualization helps to its best in understanding the mechanism.

Amine Liberation

Several chemical compounds induce amine liberation from mast cells but do not necessarily provoque the granule expulsion. For example, poly-dl-lysine induces modifications of the cellular membrane permeability which promotes ion exchange at the level of mast cell granules. Few of them are expulsed but the majority remains in the cytoplasm and appears less dense to the electrons. A cytochemical analysis has been performed to determine the composition of these granules after the polylysine action.We have previously reported that it was possible to demonstrate polyanions on epon thin sections using a cetylpyridinium ferric thiocyanate method. Organic bases are selectively stained with cobalt thiocyanate and the sulfhydryle groups are characterized with a silver methenamine reaction. These techniques permit to reveal the mast cell granule constituents, i.e. heparin, biogenic amines and basic proteins.

Considerable interest has been generated in solid state reactions between thin films of near noble metals and silicon. These metals deposited on Si form numerous stable chemical compounds at low temperatures and have found applications as Schottky barrier contacts to silicon in VLSI devices. Since the very first phase that nucleates in contact with Si determines the barrier properties, the purpose of our study was to investigate the silicide formation of the near noble metals, Pd and Pt, at very thin thickness of the metal films on amorphous silicon.Films of Pd and Pt in the thickness range of 0.5nm to 20nm were made by room temperature evaporation on 40nm thick amorphous Si films, which were first deposited on 30nm thick amorphous Si3N4 membranes in a window configuration. The deposition rate was 0.1 to 0.5nm/sec and the pressure during deposition was 3 x 10 -7 Torr. The samples were annealed at temperatures in the range from 200° to 650°C in a furnace with helium purified by hot (950°C) Ti particles. Transmission electron microscopy and diffraction techniques were used to evaluate changes in structure and morphology of the phases formed as a function of metal thickness and annealing temperature.

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.
