Table 8. Calculation of t h e Quadratic Equation for Snail Feeding 

 on Citrus Rust Mite . Refer to table 4 for source of quadratic. Table 

 7 gives calculated values. 



Y = 2.8613 - .003X^, + .0266 X^ + 1.0896X - .2993X - 1.1446 (X-N) 

 + .1392 (X-N^) + .2914 (X^-N) - .0351 (X^-N^) 



X = Average initial surface area per cubic foot = 1707.43 



X„ = Average untransformed initial mite count = 9.4111 

 2 



X = Number of snails 



N = Number of days (or nights)
