|
| The caterpillar
of Manduca sexta |
||||||||
| is eating a portion of a
tobacco |
||||||||
| plant. The
damaged portion of plant |
||||||||
| reacts to the
invasion by giving off |
||||||||
| chemical signals
that attract parasitoid |
||||||||
| wasps that lay
their eggs on the |
||||||||
| caterpillars
(their natural host), thus |
||||||||
| killing them and
controlling their |
||||||||
| populations! But
wait. There’s more! |
