Hello everyone, today I again welcome you all to this video from our agrilearner team. So friends our today’s important topic’s name is Biological Control of Cotton Ball-worm.
So guys before going further in the explanation of this topic, we will discuss the questions which were questioned in IPBS AFO 2019-20 and what more can be asked in future from this topic. Let’s move forward to the questions.
Which entomopathogenic Fungi plays an important role as a biological control agent in controlling Cotton bollworm? (IBPS AFO 2019-20)
- Helicoverpa armigera
- Beauveria bassiana
- Metarhizium anisopliae
- Spodoptera litura
The correct answer is Beauveria bassiana.
Now let’s see the explanation of this particular question. Let’s move forward to the explanation portion.
Here we will see discuss about the Biological Control of Cotton-ball with the help of endophytic fungal.
➤The endophytic fungal entomopathogens Beauveria bassiana and Purpureocillium lilacinum enhance the growth of cultivated cotton (Gossypium hirsutum) and act as biological control agents by negatively affecting the survival of American cotton bollworm (Helicoverpazea).
➤ Next point is – many fungal insect pathogens can also colonize plants as endophytes.
➤ Endophytic Beauveria bassiana and Purpureocillium lilacinum enhance cotton growth by reducing the survival of American cotton bollworm (Helicoverpazea) larvae.
➤Manipulating fungal endophytes can play a role in sustainable IPM strategies.
