Fruit fly trapping guide - IAEA Publications - International Atomic ...

II. Trapping Survey Objectives
The operational concept of survey as used
in these guidelines, is based on the following
definition as defined by the Food and Agriculture
Organization (FAO) in 1990:
An official procedure conducted
over a defined period of time to
determine the characteristics of a
pest population, or to determine
which species occur in an area.
The three objectives of trapping survey are:
A. Detection survey: To determine if species are
present in an area.
B. Delimiting survey: To determine the boundaries
of an area considered to be infested or
free from a pest.
C. Monitoring survey: Ongoing survey to verify
the characteristics of a pest population including
seasonal population fluctuation, relative
abundance host sequence and others.
III. Trapping Applications
Trapping surveys are applied in:
Infested area: to determine species presence and
to monitor established fruit fly populations (it
is assumed that no fruit fly control measures
are used in the area).
Suppression: Suppression is a process that is applied
to reach a fruit fly low prevalence area.
Trapping is applied to measure the efficacy of
control measures such as bait sprays, Sterile
Insect Technique (SIT), biological control and
Male Annihilation Technique (MAT), used in
an infested area to reduce the fruit fly population
and thereby limit damage and spread.
Eradication: Eradication is a process applied to
reach a fruit fly free area. Trapping is applied
to measure the efficacy of control measures
such as bait sprays, SIT, biological control,
and MAT, used to eliminate a pest from an
area.
Exclusion: Exclusion is a process applied to minimize
the risk of introduction or re-introduction
of a pest in a free area. Trapping is applied
to determine the presence of species that
are under exclusion measures and confirms or
rejects the free area status.
