An observational study to determine the common behaviours of seed beetles carried out across five foundation study groups at Evolvingminds.
Using the seed beetle Callosobruchus maculatus, we aimed to understand what common behaviours male and female beetles exhibited when introduced as pairs within a glass container for approximately 45 minutes. C. maculatus is a common pest of stored legumes and are easy to rear for studies to understand their lifecycle. Larvae (four instars) of this species burrow into the dry seeds and remain there by feeding on the seed for about 20 days (temperature dependent). Once they pupate they emerge from the seed as a mature adult and can readily mate with females. Females of this species (and strain) are known to be bigger than males and each female can lay up to 200 eggs in their lifetime (condition dependent)...Biology Read More
