In this paper, we introduce strongly quasi primary ideals which is an intermediate class of primary ideals and quasi primary ideals. Let $R$ be a commutative ring with nonzero identity and $Q$ a proper ideal of $R$. Then $Q$ is called strongly quasi primary if $ab\in Q$ for $a,b\in R$ implies either $a^{2}\in Q$ or $b^{n}\in Q~ (a^{n}\in Q$ or $b^{2}\in Q)$ for some $n\in \mathbb{N} $. We give many properties of strongly quasi primary ideals and investigate the relations between strongly quasi primary ideals and other classical ideals such as primary, 2-prime and quasi primary ideals. Among other results, we give a characterization of divided rings in terms of strongly quasi primary ideals. Also, we construct a subgraph of ideal based zero divisor graph $\Gamma_{I}(R)$ and denote it by $\Gamma_{I}^{\ast}(R)$, where $I$ is an ideal of $R$. We investigate the relations between $\Gamma_{I}^{\ast} (R)$ and $\Gamma_{I}(R)$. Further, we use strongly quasi primary ideals and $\Gamma_{I}^{\ast}(R)$ to characterize von Neumann regular rings.
