QUESTION THREE
RESOURCE TWO
Sexy way to kill bugs
Scientists are making ‘sex traps’ to kill mealy bugs which damage grape vines. The mealy
bug spreads the leaf-roller virus. The sex trap will use sex hormones, which are released by
the female, to lure males into a sticky trap.

Irish wasp to fight evil weevil
A tiny wasp from Ireland is to be used by scientists to fight the clover root weevil. The
weevil costs an estimated $150 million in lost production each year. The adult weevil chews
clover leaves, while the larva attacks the clover roots and root nodules. The wasp will kill the
weevil by injecting it with an egg which hatches and eats the weevil from the inside out.

The articles above give two examples of ways that scientists are trying to prevent pests and
diseases from harming New Zealand’s primary industries.
(a)
What would have been done in the past to control the mealy bug and clover root weevil?
(b)
Why are the techniques that scientists are starting to use now to control the mealy bug and
clover root weevil better for the environment?

QUESTION FOUR
Each year fruit growers run the risk of having their crops damaged by frosts. Listed below are several
methods used by growers to combat frost, each of which has positive and negative effects on the
environment:

diesel burners

sprinklers

wind machines

cloth covers

planting on hillsides.
Select ONE method that would most effectively prevent frosts while having the lowest negative
environmental impact, and justify why your selection is better than each of the other methods.
Selected method:
