A species of Acanthoscelides, Also known as Bean seed beetle, Dried bean weevil, Bean bruchid

Bean weevil larvae infest and damage legumes, leading to reduced germination and crop yield. Severe infestations can cause total stock loss, impacting food supply and causing economic harm. Control measures are crucial to mitigate these risks.

Harmful Facts About Bean weevil

Why are Bean weevil harmful to humans?

Bean weevil tends to infest stored legumes, which are a common staple in human diets. The females lay eggs on dried beans, and once the larvae hatch, they burrow into the beans, causing internal damage and spoilage. This directly affects humans as it can compromise food security by reducing the quantity and nutritional value of these essential food items, and in severe cases, can lead to a complete loss of the stored product.

What is the best prevention for Bean weevil?

To prevent bean weevil infestation, ensure that storage facilities for legumes are clean and well-sealed. Regularly inspect beans for signs of damage or larvae. Using airtight containers for storing legumes can significantly hinder the ability of bean weevil to lay eggs on the pulses. Employing pheromone traps can also monitor and control the adult population without the use of chemicals.

What are the solutions for injuries caused by Bean weevil?

Upon discovering an infestation of bean weevil, remove and discard the affected produce to prevent further spread. Clean the storage area thoroughly to remove any larvae or eggs. Freezing legumes for several days or heating them for a short period can kill any remaining insects. Maintaining a dry and cool environment can deter future infestations. During recovery of the legumes stock, ensure proper sanitation and stock management to prevent reoccurrence.

Damage Level

Severe

Bean weevil poses a severe threat to stored legumes. Adults lay eggs on dry pulses, and the emerging larvae burrow inside the beans, causing internal damage. This not only results in significant product loss but also lowers the market value. Infestations can lead to total loss of the affected stock, posing great challenges in maintaining the quality of stored legumes. Control measures are essential to prevent economic losses due to this pest.
