Black biting flies

These guys look like harmless house flies but pack a serious punch in swarms. Black flies do not transmit diseases like ticks and mosquitoes do but they sure can be a nuisance.

These small flies are commonly called “buffalo gnats” because of their humped back appearance. They are typically dark in color and appear in a variety of neutral shades from light gray to black.

It can hurt when a black fly bites because she cuts a hole into the skin so she can feast on a pool of blood. She also injects an anticoagulant to prevent the blood from clotting, which can cause a mild to the severe allergic reaction in some people.

The painfully itchy bite of the black fly is created when the female cuts a hole in the skin to suck blood from animals and people. Females will attack incessantly around the eyes, ears, scalp and occasionally on the arms and exposed legs. The pain and swelling of the bite are due to allergic reactions to foreign proteins and toxins that the female injects when feeding. Black flies transmit diseases in the tropics, such as River Blindness. Fortunately, they do not transmit any diseases to humans but can cause extreme discomfort and irritation due to their biting habits and/or great numbers.

The bites of black flies cause different reactions in humans, ranging from a small puncture wound where the original blood meal was taken to a swelling that can be the size of a golf ball.  Reactions to black fly bites that collectively are known as “black fly fever” include a headache, nausea, fever, and swollen lymph nodes in the neck.

Besides being a nuisance to humans, black flies can pose a threat to livestock.  They are capable of transmitting a number of different disease agents to livestock, including protozoa and nematode worms, none of which cause disease in humans.  In addition to being vectors of disease agents, black flies pose other threats to livestock.  For example, when numerous enough,  black flies have caused suffocation by crawling into the nose and throat of pastured animals.  On rare occasions, black flies have been known to cause exsanguination (death due to blood loss) from extreme rates of biting.  Saliva injected by biting black flies can cause a condition known as “toxic shock” in livestock and poultry, which may result in death.

Black fly outbreak across Spokane brings itchy, bleeding misery

June 2, 2017, The spokesman review

Danniele Hall was with her two young children and dog in the Dishman Hills when the black flies attacked.

“Within five minutes, our daughter’s forehead and the back of her neck were bleeding from five different bites,” Hall said. “In the same time, our son had bites all over his shoulders, and I had a bite that caused blood to run down my face.”

Her daughter’s ear and neck became swollen and one of the bites on her son was turning into a blister. Even the family dog suffered bites on his stomach.

“It’s as if they’re feeding on our skin!” she said.

Are black fly bites a health concern?

May 30, 2017, Washington news

Health officials said Monday that black fly populations seem to be on the rise.

The Hole family in Spokane Valley said they enjoy playing in their backyard, especially little Sophia. But Sophia found out the good times outside can come with something very unpleasant.

Sophia’s father, Chris Hole said “She started getting bit and we thought it was spiders at first but then we found it was black flies, they started getting her around the neck.”

Hole said his daughter has been bitten at least six times.

“She doesn’t ever feel them but she ends up getting little welty, red bloody wounds from it,” said Hole. “We don’t like her constantly being attacked when she comes out to play,” added Hole.

Blackflies are actually beneficial to our ecosystem. Black flies sup on nectar and therefore play a valuable role in the ecosystem as pollinators. They also feed and filter dissolved organic matter, making it available to other organisms within the food chain. Since these insects are vital for our ecosystem, it is of extreme importance to find a safe and non-toxic solution for the blackflies problem which would keep these insects at bay while not causing any harm to these beneficial insects.

Now, we no longer have to depend on these conventional, toxic insecticides to deal with these pests!

We need a long-term and effective solution to control their nuisance. We at C Tech Corporation have a solution to combat against these black flies.

Grain bag invader – Weevil

Often the grains are found with hollow holes in them. These tiny little holes emerge all of a sudden even when the grains are stored in the protective bags.

From where do the holes appear? Who make these holes in the grains?

Those are the weevils that are responsible for this menace!

What are weevils? Where do they come from? Why do they invade grain bags?

Let’s know the answer to these questions.

Weevil species occur in a wide range of colors and body shapes. Many are slender or oval-shaped insects. Depending on the species, weevils range in size from about 3 mm to over 10 mm in length. They are usually dark-colored—brownish to black. Some have scales or shiny hair covering part of their bodies. The most distinctive feature of weevils is the shape of their head. An adult weevil has an elongated head that forms a snout. The mouth is at the end of the snout. Some weevils have a snout that is as long as the body. Another family of beetles called Bruchidae, such as the cowpea weevil, have a different appearance from the typical weevil. They lack the elongated snout found in the Curculionidae.

Weevils feed on plants in the larval stage and as adults. Some weevils can be very destructive to crops. For many years, one of the most destructive weevils was the cotton boll weevil which feeds on cotton buds and flowers. The black vine weevil is found in many parts of the United States. It feeds on a variety of plants, including hemlocks and rhododendrons.

Often called flour bugs, because that is where they are frequently found, there are actually a number of types of weevil, including rice weevils, seed weevils, granary/grain weevils, maize weevils, and bean/pea/seed weevils, but the “true” weevils – with the snout nose, are the granary, rice, and maize weevils.

Most weevils are found in fields, gardens or orchards. A few weevils attack stored grains and seeds. They can be very destructive, and their damage is often very expensive. The most common stored product weevils are the rice weevil, the granary weevil, and the cowpea weevil.

However, a few weevils become structural pests. These are the weevils that upset homeowners because they invade homes—often in great numbers. Some of them invade in the fall. They hide during the winter and leave in the spring. Others invade in the summer when the weather starts turning hot.

But unlike beetles that live and feed on foods, these weevils actually live and feed inside the food.

The female chews a hole into a seed or grain kernel and deposits an egg inside. The female weevil then seals up the opening, leaving the egg inside. When the egg hatches (inside the grain/seed), the larva feeds on the meat inside until it is fully grown. Once fully grown, the adult weevil eats its way out of the grain/seed.
When they infest grain that is stored in bins and remains undisturbed, they can completely destroy the food.

In the home, weevils can be brought in packaged foods or they can come in from outside. Once inside, a population can grow and expand to food items stored nearby if they are not controlled.

Pests plague Negros Oriental coffee farm

Jude Torres, ABS-CBN News Posted on Sep 26 2017

DAUIN, Negros Oriental – A coffee farm in this town is fighting off an infestation of coffee bean borers and coffee weevils, which eat and destroy the coffee cherries, the local agriculture office said.

The Baslay Farmer’s Association last month noticed a defect in the coffee cherries in their 70-hectare coffee farm. In the evaluation of the Regional Crop Protection Center of the Department of Agriculture-Central Visayas, 3 hectares of the Baslay Coffee farm were found to be infested with pests.
Boll weevil bottled up in Texas’ Rio Grande Valley
Ron Smith 1 | Feb 22, 2013

The struggle against the boll weevil will continue until officials get a handle on boll weevils coming out of Mexico. The Lower Rio Grande Valley remains the last bastion of boll weevil infestation in the country, and the decades-old eradication program continues to deplete the pest’s numbers there, but as long as a viable population exists, cotton farmers cannot rest.

We can’t allow these pests to destroy our crops and grains now and then. The loss due to them is just unnecessary. Insecticides have proven inefficient in combating these pests and there’s an urgent call for stopping their menace in a non-hazardous way.

To get the solution, why not we opt for the non- hazardous, low-toxic and eco- friendly products provided by CTech Corporation.

Termirepel™ an anti-insect additive, a CTech Corporation product is an ideal solution for the prevention and control of bedbug infestation. The masterbatch of Termirepel™ can be incorporated in wires and cables which are used in domestic wiring. Termirepel™ liquid concentrate which can be mixed in paints and can be applied to damaged applications. While Termirepel™ lacquer can be used as a topical application which can be applied to furniture, walls, ceilings etc. It follows 6 pronged strategies which are extremely effective on weevils as well as insects like ants, beetles, grasshopper, termites etc.

Termirepel™ is a non-toxic and non-hazardous anti-insect additive. It is thermally stable and does not degrade on exposure to heat and sunlight. It does not kill or harm the insect but repels them. It does not volatilize and does not degrade the soil.
