A multidisciplinary approach considers inte-gral control and favours biological control measures, whereby it is crucial to conduct a com-prehensive examination of the existence of poten-tial candidates to prevent the spread and destroy generative propagation of insects, in particular the invasive ones. Such an integral approach makes it possible to create conditions required for restoration and protection of stocks of seeds and forest cul-tures, as well as seed stocks for human consump-tion. This would ensure the future use of species whose seeds are kept for restoration of rare species, and most importantly, for keeping stocks with enormous economic and social importance. This paper provides an overview of occurrence and use of potentially harmful Bruchinae insect, honey locust seed beetle, the use of which in practice would be compliant with the principles of sustaina-ble development, given the proven competition with bean weevil. The researched Bruchinae species Megabruchidius tonkineus (Pic, 1904) has recently been proven not to be monophagous in Serbia, and to attack and infest bean seeds in addition to Ken-tucky coffee tree seeds. During a three-year re-search (in the period 2019 – 2021), analyses were conducted on data from statistically important samples from 3 localities across the county (3 ex-perimental host plants per locality). The second Bruchinae beetle is the best-known bean pest Acan-thoscelides obtectus Say. The two noted seed pred-ators were over this period subjected to various laboratory examinations in order to collect data on their general impact on one another. Such a combi-nation or community may form the key for adop-tion of the host to the pests, modifying the plants themselves phenotypically, genetically and chemi-cally, and in turn the probability of attack by a known seed predator.
