Thus it is only a matter of when, not if, some insects develop resistance to Bt.

Most insects cannot be properly identified until they are mature adults, usually the time when insects have developed wings.

These insects had developed an alarming resistance to bugspray and were out of control most of the time.

The chromosome household is disturbed, the genes are changed and insects develop in an unprogrammed sequence.

Aquatic insects have developed freeze tolerance much like their terrestrial counterparts.

These insects (Figure 1) always develop not from a single fertilized egg but from two genetically different cells.

Weeds and insects develop genetic resistance to farm chemicals, often forcing farmers to use ever greater amounts to achieve the same effect.

His studies, he said, show that insects had developed close relationships, which included pollination, with plants that came before angiosperms.

Many insects have developed ways to defend against these plant defenses (in an evolutionary arms race).

Pearson devotes what is left of his life to helping the insects develop their society.
