BibTeX, biblatex and biber ⇒ Change comma to colon between volume and year in apacite

[Catherinejj]

Hi,

I use a natbib package and bibliography style of "apacite". The reference format I would like to get is :

Coeurdacier, N. and Rey, H. 2013. Home bias in open economy financial macroeconomics. Journal of Economic Literature, 51(1):63–115.

But what I am currently getting is :
Coeurdacier, N. and Rey, H. (2013). Home bias in open economy financial macroeconomics. Journal of Economic Literature, 51(1), 63–115.

I would like to change the comma between volume (number) and year into the colon. Any ideas? Thanks.

The code I am using is
\documentclass[11pt]{article}
\usepackage{times}
\usepackage{setspace}
\usepackage[margin=1in]{geometry}
\usepackage{apacite}
\usepackage{natbib}
\setlength{\bibhang}{0pt}
\AtBeginDocument{
\renewcommand{\BBOP}{}%%% Removing parentheses around year in bibliography
\renewcommand{\BBCP}{}
}

\begin{document}
blah..blah..blah.

\bibliographystyle{apacite1}
\bibliography{mybib}
\nocite{*}

\end{document}

.bib file entry is
@article{coeurdacier2013home,
title={Home Bias in Open Economy Financial Macroeconomics},
author={Coeurdacier, Nicolas and Rey, Helene},
journal={Journal of Economic Literature},
volume={51},
number={1},
pages={63--115},
year={2013}
}
