BIOLOGICAL insecticide Beauveria bassiana
Fellow farmers and agricultural lovers all, this time gateway Agriculture will be slightly reviewed mold or mildew natural enemies of insect pests such as various types of Beauveria bassiana . This fungus commonly known as insect pathogenic fungi are fungi that can cause disease in insects. How it works is this mushroom will make the pain then causes the insect pest is dead. Some examples of insects can be controlled by Beauveria bassiana include various types of leafhoppers, grasshoppers, locusts rice bug, caterpillar, javelin and sundep outs (borer),.
Beauveria bassiana is naturally present in the soil as a saprophyte fungus. The growth of the fungus in the soil is influenced by soil conditions, such as organic matter, temperature, humidity, insect eating habits, their synthetic pesticides, and time aplikasi.Secara general, temperatures above 30 ° C, reduced soil moisture and the antifungal or pesticides can inhibit growth.
How mushrooms Beauvaria bassiana infects the body starts to contact insect host, enter the host's body, reproduction in one or more network host, then contact and infect a new host.
According to some articles that maspary read Beauveria bassiana in to the host insect's body through the skin, gastrointestinal tract, spiracles and other openings. Fungal inoculum which is attached to the body of the insect host will germinate and grow to form a tube sprouts, then enter the body through the skin. Penetration done mechanically or chemically by removing the enzyme or toksin.Pada further processing, mold will reproduce in the host body. The fungus will grow in the body and invade host tissues throughout the body, so that the dead insects. Fungal mycelia penetrate to the outside of the body of the host, grow over the host body and produce konidia.Dalam matter of days, the larvae will die. Insects with the fungus Beauveria bassiana will die with hardened body like a mummy and a mold covered the body with a white host.
In infection, Beauveria bassiana will look out of the body infected insects first of the attachment (apendages) as between segments of the antenna, between segments of the head with the thorax, between segments of the thorax with abdomen and the abdominal segment with cauda (tail). after a few days later the entire surface of the infected insect body will be covered by a mass of colored mushrooms putih.Penetrasi entomopathogenic fungi often occur in the membrane between the capsule head with the thorax or between the segments as well as fungal mycelium apendages out the first time in these parts.
From the information obtained Gate Farm has been known for more than 175 types of insect pests that hosts the fungus Beauveria bassiana . Great is not it ??? Based on the findings of this fungus effectively control rice pest insect pests (Leptocorisa oratorius) and brown plant hopper shaft (Nilaparvata lugens) in rice plants and pest infestation (Aphis sp.) On vegetable crops. Some other examples that hosts the B. bassiana is crickets, silkworms, and red ants. Because B.bassiana can attack almost all kinds of insects, mushrooms have been classified as non-selective pesticides that are not recommended for use in assisted conception crops by insects.
The use of this fungus to eradicate the pest can be done by several methods. These fungi can be used to trap pests. As for how it's used by inserting Beauveria bassiana and gimmickry in the form of interest aroma insect (pheromones) into a bottle of mineral. Insects will fit into the bottle and exposed to the spores. Eventually causing the infected insects. Its application is by spraying method.
Insects that have been infected with Beauveria bassiana will further contaminate the environment, either by producing spores penetrate the cuticle out of the host's body, as well as through contaminated feces. Insects sound will then be infected. The line is called horizontal transmission of pathogens (inter / intra generation).
According to Gateway Agriculture constraints in the field of biological pesticides, biological pesticides, which are highly sensitive to environmental conditions. If the biological pesticide applications in environmental conditions that are less favorable for the development of pesticide application biological pesticides will be less effective. For example if extreme heat or cold, humidity is too low, the wind is too strong etc. Then the biological pesticide application is to consider the state of the environment.
So a bit of articles on Beauveria bassiana which can be used as an alternative non-chemical pest control pests on food crops and horticulture. Hope Maspary and Gateway Agriculture Hopefully this article can give you new insights and inspiration in controlling pests on plants (maspary).
