Chromosomes and their meiotic behavior in two families of the sub-order heteroptera

Summary Eurydema pulchrum Westw. and Bagrada cruciferarum Kirkadly (Pentatomidae)
show 2n 1412AXY. Autosomes show gradation in size, X is of medium size while Y is the
smallest element. Both X and Y are positively heteropycnotic in diffused stage but become
isopycnotic in diplotene stage and divide equationally during meiosis-I. At metaphase-II, X
and Y get associated, the association being strong forming a pseudobivalent XY in
Eurydema pulchrum while weak in Bagrada cruciferarum. A definite pattern of arrangement …
