^aIncludes cells with more than five CABs.

^bThe CABs/cell frequencies have been calculated assuming that the cells with more than five CABs contained only five CABs, and are therefore an underestimation of the actual frequencies.

^cNormal wandering third larvae with comparable body and brain sizes.

^dNot significantly different in the Chi square test.

^eSmall larvae dying at the late second/early third instar.
