2. Behavioral Control
Dispense a large amount of sex
pheromone within the crop.
Disturb the normal behavior of male
insects so that they cannot find female
hence interfering with mating.

3. Behavioral controls utilize some
chemicals to modify insect pest
behavior, and control pest without the
use of toxins, thereby playing an
important role in area-wide control
system. At present, behavioral
modification method e.g
(pheromones) have been used to
confuse or trap the male population.

4. Pheromones- are chemicals
released by an organism into its
environment enabling it to
communicate with other members
of its own species.

5. 1. Monitoring with Attractant
 Baited is an important component of pest
management program.
 Pheromones are widely used in pest
monitoring due to the specificity, selectivity
and mainly for not affecting the health of
workers and environment.

6. Food attractant can also be used for
monitoring pest. In horticulture,
the technique is widely used to
monitor fruit flies. In this case,
Food baits are used in traps to
attract insects and pest.

8. 2. Mating Disruption
 This method consist of distributing a large
amount of synthetic sex pheromones in the
field, aiming to prevent the male to find a
female, disrupting mating. Therefore, new
pest generations do not occur on treated
area.

9. An ant lay a trail pheromone to direct
other ants to a food source. Aphids
release an alarm pheromones that
warns other aphids of potential danger,
usually the presence of a predator or
parasites.

10. Mating Disruption

11. 3. Attract and Kill ( A&K) System
 This strategy is a new pest management
technique, an extension of mating
disruption, which is characterized by the
inclusion of and insecticide (killing agent)
in addition to the pheromone to achieve the
same control methods as mating
disruptions.

12. Attract and kill system effective against
Alfalfa Looper.
Starve alfalfa looper adults (moths)
were strongly attracted to the attract
and kill station in a flight tunnel, and
90.9 % of female moths and 87.6 % of
male moths that contracted the station
died.

14. 4. The Push-Pull Strategy
 Insect control methods exploiting natural
chemical messengers, collectively semio-
chemicals, are becoming increasingly familiar.
 “Push-Pull”, also called stimulo-deterrent diversion
involves “pushing” the insects away from the
harvestable, economic crops, and “pull” onto a trap
crop where their population is reduced by
biological control agent specific but slow-acting
insecticide.

15.  Used for controlling agricultural pest by using
repellant “push” plants and trap “pull” plants.
 Cereal crops like maize or sorghum are often
infested by stem borers. Grasses planted around
the perimeter of the crop attract and trap the pest.
Whereas other plants like Desmodium, planted
between the rows of maize repel the pest and
control the parasitic plant STRIGA.

16. Push-Pull Strategy

17. The benefits of push-pull strategy
include a lower requirement for broad
spectrum pesticides, saving these
valueable materials for a “ fire fighting
role”. There is less risk of producing
population resistant insect.

18. 5. Mass Trapping
 The purpose is to reduce the number of
individuals of the next generation removing
only males of both insect sexes of the area.
 The mass trapping, when is not enough by
itself to control pest population, can be used
in combination with other methods of pest
control within the philosophy of integrated
pest management.

19. The adult phase of thrips and
whiteflies can be caught in huge
numbers with to river sticky.raps.

21. 6. Attractive Lures and Toxic
Lures
 Another aspect of behavioral control is used
of secondary plant substances they play an
important role in the feeding of
monophagous or oliphagous insects. These
substances are used in insect behavioral and
biology studies, such as
attraction/repellence, feeding and
oviposition deterrence.

22. Initial control of flies in Africa used
odor released by oven or buffalo urine
to attract flies to cloth. Dropped with
insecticides. Later, flies were attracted
to electricified nets with these and
other odorants. An alternative to
conventional insecticides could make
use of insect pathogens as bio-
pesticides if they can kill the attracted
insect before mating occurs.
