Blood sucking bugs contain parasites and drug resistance

Initial studies have shown that the bug bugs feed on the parasite's blood and they are also resistant to pesticides.

Detecting single-cell parasites

Associate Prof. Dr. Truong Xuan Lam, Institute of Ecology and Biological Resources, Vietnam Academy of Science and Technology said, blood-sucking bugs are a blood-sucking insect so its injection makes people uncomfortable, wide allergies , even fever, especially for children. In addition, this species is known as a Trypanosoma cruzi parasite vector in Latin America causing Chagas disease. In our country during the study, scientists have confirmed the presence in the digestive system of kissing bugs with single-celled parasites of Trypanosoma genus (the name has not been identified).

At the moment, it has not been determined to what extent the parasite is causing the disease, but in the aspect of entomology, it is necessary to carefully study the spread and spread of this insect, especially the long follow-up arrangement. term for those who have been stung by stinking bugs, identify the parasite species name and establish an adaptive epidemiological surveillance system to prevent the occurrence of Chagas disease in Vietnam.

Dr. Pham Thi Khoa, Institute of Malaria - Parasites - Insensitive insects, Chagas disease is mainly distributed in the new world. The causative agent is the Trypanosoma cruzi single-celled parasite blood which invades the body through the individual bugs that suck blood on the subject or mucosa skin. Since early 2010, Triatoma rubrofasciata has caused many concerns and worries among people in many places in Vietnam. Their activities mainly suck blood at night. In particular, biting bugs cause itching and swelling, but so far there have been no studies of parasites in the kissing bugs and the possibility of transmission to humans.

High drug resistance

During the study of stink bugs, Dr. Pham Thi Khoa raised them and was surprised at the development of this species. Specifically, the reproductive ability of stink bugs is very high regardless of laboratory conditions. A female stink bug that absorbs rat blood every 2 days can lay 327 eggs in 7 months.

In addition, to prepare a campaign that can directly fight the kissing bugs, aims to assess the susceptibility of insects as well as help people reduce stress because of anxiety of burning stink bugs, Dr. Pham Thi Khoa tested them with pesticides commonly used in Vietnam. Stink bugs were tested for pesticides in the form of impregnated paper for 1-3 days, depending on the stage of development (second or fifth pupae stage), indicating that they are resistant to alpha-cypermethrin at 30mg / m 2 .

Schofield CJ (UK) has "devised" to reduce blood sucking bugs and epidemiological control for Vietnam or Southeast Asia: Insect surveillance is necessary to avoid major risks. New and non-passive vector transmissions like Latin American countries. In addition, more data is needed to understand the migration routes of local species, homeowners, interests, active, passive dissemination capabilities and mechanisms of attacks on people. A long-term epidemiological surveillance must be established to confirm that the parasite found in the kissing bugs sucking blood collected indoors does not harm humans.

For resistant stink bugs, it is necessary to use trained technical treatment teams, use good quality pesticides, modern application equipment to make sure to prevent the bugs from sucking blood.
