Result of regression of LC50 and larval diets’ protein content
| Parameter estimate | r 2 | ||
|---|---|---|---|
| Age (instar) | a (y intercept) | b (slope) | |
| Second | −2.24 (0.53) | 0.21a (0.02) | 0.56 (0.43) |
| Fourth | 1.18 (0.52) | 0.14b (0.02) | 0.82 (0.42) |
General form of regression is y = a + bx, where y is the LC50 of Cx. quinquefasciatus on temephos, a is the y intercept, b is the change in LC50 per change of protein percentage, x is the protein content. Numbers in parentheses are standard error of the estimates. Means numbers in same column followed by different letters are significantly different at P < 0.05.
