Beauveria bassiana is a fungus that occurs naturally in soils worldwide and acts as a parasite on various arthropod species, infecting them without the need to be ingested. It is used as a biological insecticide to control pests such as termites, thrips, whiteflies, aphids, and beetles. The rate at which Beauveria spores kill their host depends on temperature; small potato beetle larvae are killed in 3-5 days at a constant 72 oF, while under field conditions, it may take 7 to 10 days. The time it takes for pest control to work varies, but it is important to give the treatment time to be effective and to follow any advice given by the exterminator to prevent pests from returning.

Beauveria bassiana is a naturally occurring fungus in soils worldwide
Beauveria bassiana is a naturally occurring fungus found in soils worldwide. It was discovered in 1835 by Italian entomologist Agostino Bassi, who found it in silkworms (Bombyx mori). It is a parasite that infects various arthropod species, causing white muscadine disease. It is an entomopathogenic fungus, which means it does not need to be ingested by its host to cause infection. Instead, the spores of the fungus simply need to come into contact with the host's cuticle (skin). Once the host is infected, the fungus proliferates throughout the insect's body, feeding on its nutrients and producing toxins, eventually killing the host.
Beauveria bassiana is a type of entomopathogenic fungus, which means it acts as a parasite on arthropods, causing disease. It infects a broad range of insects, including whiteflies, aphids, thrips, grasshoppers, and beetles. It is used as a biological insecticide to control pests such as termites, thrips, whiteflies, aphids, and beetles. It is also being investigated for its potential use in controlling bed bugs and malaria-transmitting mosquitoes.
The fungus is named after Bassi, who discovered it and determined it to be the cause of the muscardine disease. Further studies were conducted by Jean Beauverie in 1911, and the next year, Jean Paul Vuillemin made it the type species of his new genus, Beauveria. The species was also previously known as Botrytis bassiana and Tritirachium shiotae, among other synonyms.
Beauveria bassiana is a safe and effective insecticide as it rarely infects humans or other animals. It can be used until the day of harvest since it is not harmful to consumers. However, it is still recommended to follow safety precautions and wear protective clothing when applying products containing the fungus.
The rate at which Beauveria bassiana spores kill their host depends on the temperature. In a controlled environment of 72°F, small potato beetle larvae are killed in 3-5 days. In field conditions, it may take 7 to 10 days to kill larvae.

It causes white muscadine disease in insects, killing them within days
Beauveria bassiana is a naturally occurring fungus found in soils worldwide. It causes white muscadine disease, a fatal condition for many insects. When spores of this fungus come into contact with the cuticle (skin) of susceptible insects, they germinate and grow directly through the cuticle to the inner body of their host. The fungus then proliferates throughout the insect’s body, producing toxins and depleting the insect of nutrients, eventually killing it. The rate at which Beauveria spores kill their host depends on the temperature. For example, at a constant 72 oF, small potato beetle larvae are killed in 3-5 days. Under field conditions, it may take 7 to 10 days to kill larvae.
White muscadine disease gets its name from the fact that, once the fungus has killed its host, it grows back out through the softer portions of the cuticle, covering the insect with a layer of white mold. This downy mold then produces millions of new infective spores that are released into the environment.
Beauveria bassiana differs from other insect pathogens such as Nosema locustae in that it does not need to be ingested by the host. Instead, B. bassiana spores simply need to come into contact with a host to infect it. This characteristic makes Beauveria bassiana a useful biological insecticide to control a number of pests, including termites, thrips, whiteflies, aphids, and various beetles. It is also being investigated for use in controlling bed bugs and malaria-transmitting mosquitoes.
As a biological insecticide, Beauveria bassiana products are considered reduced-risk pesticides. They can be applied up until the day of harvest, as the residue is not harmful to consumers. However, applicators should wear long-sleeved shirts, long pants, and a dust/mist filtering respirator when handling these products. Beauveria products should not be applied to areas where bees are actively foraging or to water, as they are potentially toxic to fish.

It does not need to be ingested by the host, only to come into contact with it
Beauveria bassiana is a fungus that grows naturally in soils worldwide and acts as a parasite on various arthropod species, causing white muscardine disease. It is named after Italian entomologist Agostino Bassi, who discovered it in 1835 in silkworms.
B. bassiana is unique in that it does not need to be ingested by the host insect to be effective. The microscopic spores of the fungus only need to come into contact with the body of an insect host to infect it. Once the spores come into contact with the host's cuticle (skin), they germinate, penetrate the cuticle, and grow inside the insect's body. The fungus then proliferates, producing toxins and draining the insect of nutrients, eventually killing it within a matter of days.
The ability of B. bassiana to infect the host without ingestion sets it apart from bacterial and viral pathogens of insects. This contact-based infection makes B. bassiana a highly effective biological insecticide for controlling a range of pests, including termites, thrips, whiteflies, aphids, and various beetles.
The use of B. bassiana as a natural insecticide offers several advantages. Firstly, it can be used up until the day of harvest since its residue is not harmful to consumers. Secondly, it is generally non-toxic to beneficial insects, although care should be taken to avoid application in areas where bees are actively foraging. Additionally, B. bassiana is effective against a broad range of insects, although different strains may have narrower host ranges.
In conclusion, the effectiveness of B. bassiana in pest control lies in its ability to infect the host without ingestion. This contact-based infection, coupled with its broad host range and low toxicity to beneficial insects, makes it a valuable tool in managing various pests.

It is used as a biological insecticide to control pests such as termites, thrips, and beetles
Beauveria bassiana is a naturally occurring fungus in soils that has been researched for pest control. It is used as a biological insecticide to control pests such as termites, thrips, and beetles. When B. bassiana spores come into contact with the cuticle (skin) of susceptible insects, they germinate and grow directly through the cuticle to the inner body of the host. The fungus then proliferates throughout the insect's body, producing toxins and draining the insect of nutrients, eventually killing it.
B. bassiana causes white muscadine disease in a range of insects, including thrips, certain types of beetles, whiteflies, aphids, and grasshoppers. It infects the insect upon contact and does not need to be ingested by the host. Once the host insect is infected, the fungus rapidly grows inside the insect, feeding on its nutrients and producing toxins. When the host dies, the B. bassiana covers the carcass in a layer of white mold that produces more infective spores.
Thrips are tiny, cigar-shaped, slender-bodied bugs that are brown, yellow, or black. They are hard to spot due to their small size, and the damage they cause often resembles a nutritional or disease problem rather than an insect issue. Thrips can be found on various plants, from flowers to crops, including asparagus, avocado, beans, lettuce, strawberries, and tomatoes. They damage plants by feeding on their juices, and they move quickly and travel in clusters.
The rate at which B. bassiana spores kill their host is temperature-dependent. For example, at a constant 72 degrees Fahrenheit, small potato beetle larvae are killed in 3-5 days. Under field conditions, it may take 7 to 10 days to kill larvae. B. bassiana is a reduced-risk pesticide, but it is still recommended to take safety precautions when applying products containing the fungus.

B. bassiana is generally considered safe as an insecticide, but applicators should wear protective clothing.
B. bassiana infects its host by releasing spores that come into contact with the cuticle (skin) of susceptible insects. The spores then germinate and grow directly through the cuticle to the inner body of the host. The fungus proliferates throughout the insect's body, producing toxins and draining the insect of nutrients, eventually killing it.
As an insecticide, B. bassiana spores are sprayed on affected crops as an emulsified suspension or wettable powder or applied to mosquito nets as a mosquito control agent. It is used to control a number of pests, including termites, thrips, whiteflies, aphids, and various beetles.
While B. bassiana is considered a reduced-risk pesticide, applicators should still take precautions when applying products containing the fungus. It is recommended to wear long-sleeved shirts and pants, along with a dust/mist filtering respirator and goggles. These precautions are important as the spores may exacerbate breathing difficulties, and it is also recommended to avoid applying the product to areas where bees are actively foraging.
Additionally, B. bassiana products should not be applied to water as they are potentially toxic to fish. It is also important to note that while the fungus rarely infects humans or other animals, there has been at least one case of human infection reported in an individual with a suppressed immune system.
