Propagation of Tribolium pusillum

Tribolium pusillum (Nees) H.P.Linder & Davidse, commonly known as the darkling beetle, is a pest that infests stored products like grains, flours, and cereals. While this beetle is considered as a pest, there is no denying that it is still an insect that can be propagated for various purposes such as scientific studies and as a food source for insectivorous animals.

Breeding and Rearing

The most common method of propagating Tribolium pusillum is through breeding and rearing. This process involves creating an artificial environment that mimics the insect's natural habitat, which is dry and warm. A breeding chamber is set up, either using jars or containers, and filled with grain products like wheat flour and wheat germ. Adult beetles are added to this chamber, and they will start to lay eggs within 2-3 days. The eggs hatch into larvae and then pupae before finally emerging as adult beetles. As the adult beetles emerge, they will mate and lay eggs, starting the process all over again.

Collection from the Wild

Another way to propagate Tribolium pusillum is by collecting them from the wild. Given that these beetles are commonly found in stored products and grain storage facilities, it is relatively easy to find them in their natural habitat. However, it is important to note that this method may not be suitable for large-scale propagation as it may lead to the depletion of their population in the wild, which can have an adverse effect on the ecosystem.

Conclusion

Overall, the propagation of Tribolium pusillum can be achieved through breeding and rearing or by collecting them from the wild. While these methods may have their advantages and disadvantages, they can be useful for various purposes. Careful consideration is needed when deciding which method to use to ensure that the population and ecosystem are not negatively impacted.
