By using the maximum-likelihood analysis, functional response types obtained from P. ramburi, which is a function of the number of P. manihoti are preyed upon by many P. manihoti available. This shows that the type of functional response is type II (Figure 9). According to [1], there are three types of functional response, type 1 is a linear functional response type where predation rate increased or decreased in relation to the increase or decrease in prey populations. Type II functional response, often called the hyperbolic functional response in which the rate of predation decreases with increasing prey density. Type III, also known as the sigmoid functional response type, where the predation rate was initially slow, then increased at a rate more quickly,

before it finally became constant. The first type is usually found in passive predators just as the spider. While type II, commonly occurs in laboratory experiments, with particular prey [9].
