  In this article, we explore two distinct issues. Initially, we examine the
utilization of the Pontriagin maximum principle in relation to fractional delay
differential equations. Additionally, we discuss the optimal approach for
solving the control problem for equation (1.1) and its associated payoff
function (1.2). Following that, we investigate the application of the
Pontryagin Maximum principle in the context of Volterra delay integral
equations (1.3). We strengthen the results of our study by providing
illustrative examples at the end of the article.
