Environmental factors and random variation have strong effects on the dynamics of biological and ecological systems. In this paper, we propose a stochastic delay differential model of two-prey, one-predator system with cooperation among prey species against predator. The model has a global positive solution. Sufficient conditions of existence and uniqueness of an ergodic stationary distribution of the positive solution are provided, by constructing suitable Lyapunov functionals. Sufficient conditions for possible extinction of the predator populations are also obtained. The conditions are expressed in terms of a threshold parameter ${\mathcal R}_0^s$ that relies on the environmental noise. Illustrative examples and numerical simulations, using Milstein's scheme, are carried out to illustrate the theoretical results. A small scale of noise can promote survival of the species. While relative large noises can lead to possible extinction of the species in such an environment.

Shows numerical simulations of deterministic DDEs (1) (left) and SDDEs (2) (right), when $\tau_1 = 1.25$, $\tau_2 = 0.6$ and $\tau_3 = 0.5$, with noise intensities $\sigma_1^2 = 0.08$, $\sigma_2^2 = 0.1$, $\sigma_3^2 = 0.06$, and parameter values: $r_1 = 0.2$, $r_2 = 0.6$, $K_1 = 0.7$, $K_2 = 0.8$, $\alpha_1 = 0.3$, $\alpha_2 = 0.6$, $\alpha_3 = 0.8$, $\beta = 0.1$, $\delta = 0.8$, $a_1 = 1$, $a_2 = 1.4$. For ${\mathcal R}_0^s>1$, the stochastic model has a unique ergodic stationary distribution $\pi(.)$ of stochastic system (2)
Numerical simulations of deterministic DDEs (1) (left) and SDDEs (2) (right), with parameter values given in Example 2, with noise intensities: $\sigma_1^2 = 0.03$, $\sigma_2^2 = 0.02$ and $\sigma_3^2 = 1.4$. When ${\mathcal R}_0^s<1$, we can clearly see that the predator goes to extinct
Shows numerical simulations of deterministic DDEs (1) (left) and SDDEs (2) (right), with the same parameter values of Figure 2, but with noise intensities $\sigma_1^2 = 1.2$, $\sigma_2^2 = 1.2$ and $\sigma_3^2 = 0.5$. When $r_1<\frac{\sigma_1^2}{2}$, $r_2<\frac{\sigma_2^2}{2}$ and ${\mathcal R}_0^s<1$, we can clearly see that all the species goes to extinct. A strong intensity of noise can be a cause for extinction of the prey species, which will also drive predator population to extinct
Numerical simulations of deterministic DDEs (1) (left) and SDDEs (2) (right), with parameter values of Figure 1, but with $\tau_1 = 10$, $\tau_2 = 0.1$ and $\tau_3 = 0.1$, under the noise intensities $\sigma_1^2 = 0.2$, $\sigma_2^2 = 0.2$ and $\sigma_3^2 = 0.2$. Clearly, time-delays can lead to Hopf-type bifurcations of deterministic systems
Shows the effect of white noise to prevent the explosion of the population. When $\beta = 0.5$, with the same parameter values of Figure 1, there is an explosion of population with deterministic model (left); While the noise prevent such explosion of the population (right)
One biological meaning for the parameters of model (2)
