  Recently, we proposed a new approach using a punctured Elliptic curve in the
CHY framework in order to compute one-loop scattering amplitudes. In this note,
we further develop this approach by introducing a set of connectors, which
become the main ingredient to build integrands on $\mathfrak{M}_{1,n}$, the
moduli space of n-punctured Elliptic curves. As a particular application, we
study the $\Phi^3$ bi-adjoint scalar theory. We propose a set of rules to
construct integrands on $\mathfrak{M}_{1,n}$ from $\Phi^ 3$ integrands on
$\mathfrak{M}_{0,n}$, the moduli space of n-punctured spheres. We illustrate
these rules by computing a variety of $\Phi^3$ one-loop Feynman diagrams.
Conversely, we also provide another set of rules to compute the corresponding
CHY-integrand on $\mathfrak{M}_{1,n}$ by starting instead from a given $\Phi^
3$ one-loop Feynman diagram. In addition, our results can easily be extended to
higher loops.
