    "abstract": "We study the steady state properties of an insect (spruce budworm) outbreak\nmodel in the presence of Gaussian white noise. Based on the corresponding\nFokker-Planck equation the steady state solution of the probability\ndistribution function and its extrema have been investigated. It was found that\nfluctuations of the insect birth rate reduces the population of the insects\nwhile fluctuations of predation rate and the noise correlation can prevent the\npopulation of the insects from going into extinction. Noise in the model can\ninduce a phase transition.",
