Oxygen demand of bean bruchids (Acanthoscelides obtectus Say)

July 2020

The common bean (Phaseolus vulgaris L) is an important crop in many countries and its safe storage is crucial in maintaining a sufficient and high quality food supply for the community. A non-chemical storage technique, hermetic storage, is being used to control the bean bruchid (Acanthoscelides obtectus Say), a beetle which can cause large losses to stored beans. Experiments were carried out using hermetically sealed...

Determination of appropriate packaging materials for cowpea seed storage

June 2019

Quality seed is an important resource for any seed-propagated crop. Cowpea (Vigna unguiculata) seed is prone to cowpea weevil (Callosobruchus maculatus) infestation during storage. This can result in 100% seed loss when stored without treatment. Smallholder farmers in Kenya use traditional methods of storage and occasionally accompanied by pesticides treatment. Due to health concerns, pesticide use is discouraged....
