Chemical pesticide –
Guideline for honeybee semi-field test
1 Scope
This Standard specifies the trial conditions, bee colony management, methods, quality
control, statistical analysis, test report and other basic requirements for honeybee
semi-field test for the effects of pesticides.
This Standard applies to the semi-field test of the effects of chemical pesticides on
honeybee; it can work as a reference for other pesticides.
This Standard does not apply to volatile and insoluble chemical pesticides.

3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
semi-field test
A trial process in which the controllable field conditions, such as cages, tunnels and
tents, are used to observe the effects of pesticides on the population and development
of honeybees.
3.2
exposure
to which pesticides are applying or has been applied; the post-exposure stage is the
monitoring stage, including the several investigations of colony conditions, and
evaluations of honeybee mortality and activities, etc.
5 Trial method
5.1 Materials and conditions
5.1.1 Trial bees
The bee type for the trial is a representative local bee species which has a definite
strain. The bee colony for the trial shall come from the same breeding strain; the
original and quality shall be reliable. Bee colony having any visible biological pest or
disease, shall not be used for the trial. Bee colony shall not be treated with pesticides
within 4 weeks before it is used for the trial. Queen bees shall be hatched from the
sister queens of the same batch which do mating flight at the same time. Only the
healthy bee queens with strong fecundity, which are newly-bred before the trial, can
be used for the trial. Each colony shall contain 3000 ~ 5000 worker bees and 3 full
frames at least. But it can be adjusted in accordance with the objectives of the trial.
Each colony shall contain all brood stages and an appropriate amount of stores of
pollen/nectar for the development of brood. The colony for the trial shall be in the prime
breeding period or active foraging period.
5.1.2 Test crops
Select crops which are highly attractive to bees, such as rape, cotton and so on. When
the test product is a systemic seed treatment agent or granula, the realistic target crops
of nectar/pollen source recommended for it shall be used.
5.1.3 Test products
Formulated products of pesticides shall be used.
5.1.4 Major equipment and facilities
5.1.4.1 Beehives
Local commonly-used beehives need to be used; or they are customized as required
by the trial.
5.1.4.2 Dead-bee traps
In order to collect dead bees, dead-bee traps shall be installed at the front end of the
entrance of each beehive for the trial, at least 3 d before the investigation of honeybee
mortality. Dead-bee traps shall be made of nonirritant, odorless materials such as
distance between the boundary of the whole trial area and the surrounding field shall
be more than 3 m. There shall be not other agricultural activities than the trial, such as
fertilizer application and control of plant diseases and insect pests; it shall be ensured
that the fertilizer used, pesticide products, their operating process, etc. will not exert
any effect on the results of the trial.
5.2.1.2 Monitoring stage
A site with abundant nectar source (such as wild flowers) is selected as the feeding
and monitoring points of the bee colony at the pre-exposure stage and post-exposure
stage; the distance between the monitoring point and the test field shall be greater than
3 km to prevent honeybees from flying to the test field for the exposure stage before
and after the exposure stage. Around the monitoring point, there shall be no flowering
crops which attract honeybees to forage on to prevent honeybees foraging on
pollen/nectar containing other pesticides, which interfere the results of the trial. When
the external food is insufficient, artificial feeding can be done. The food consumption
of the colony shall be recorded.
5.2.2 Test duration
The test duration is decided in accordance with the development period of test crops,
the pesticide application period of control target and the objectives of the trial.
5.2.3 Management of test colony
In accordance with the investigation results of all brood state proportions of the colony
before exposure, coordinate and distribute the colony between all treatments. The time
of migration of the test colony can be the dusk or evening when the colony finishes the
flight activities of the day, or the morning before honeybees start flight activities. When
the colony is kept in the test cage, one water source free of contamination needs to be
provided for honeybees (it is preferably prepared independently outside the beehive
or added directly to the feed bunk inside the beehive if necessary). When the
nectar/pollen of the test crops is not abundant, the colony shall be fed with an
appropriate amount of sugar (honey) water and/or pollen, but in order to ensure the
activeness of the foraging activities of honeybees, they shall not be fed excessively.
When the colony is kept at the monitoring point, feeding management can be done by
following the experiences of the local bee keepers, but during the whole trial process,
the following operation shall not be done for the test colony.
a) using pesticides toxic to queen bees or worker bees to contro...
