Are diamondback moth poisonous?
Are diamondback moth poisonous?
The diamondback moth was the first insect found to have become resistant to biological control by the Bt toxin (from Bacillus thuringiensis) in the field. Bt toxin is poisonous when ingested by insects but not mammals, so it was used to target low infestation levels of the moth.
What do diamondback moth eat?
Host plants: Diamondback moth larvae feed only on plants in the mustard family (Brassicaceae). This includes canola, mustard, and cruciferous vegetables (such as broccoli, cauliflower, cabbage, kale, radish and turnip). Larvae will also feed on some wild cruciferous plants, such as wild mustard.

How do you manage Plutella xylostella?
xylostella control. Chemical control of P. xylostella using a synthetic pyrethroid is recommended when larval density exceeds an economic threshold, which varies in relation to the growth stage of the crop and environmental conditions [79,80].
How do you control DBM in cabbage?
Cabbage plants intercropped or sprayed with chlorpyrifos against the DBM pests recorded significantly higher growth and yield and less pest damage compared with controls. Intercropping cabbage with onion, tomato or pepper was found to be as effective as spraying the cabbage with chlorpyrifos.
How do you control DBM?

- Grow two rows of mustard after every 25 rows of cauliflower/ cabbage as a trap crop at the time of planting.
- Mustard is sprayed with Nuvan 2 mL/L as soon as it germinates.
- Installation of light traps for adult DBM @ 3 traps/acre.
