to place them. Agricultural extension does not<br />

currently tra<strong>in</strong> farmers about ways to manage<br />

their crops for maximum poll<strong>in</strong>ation.<br />

Extension services need to develop courses<br />

and educational material. They should develop<br />

c<strong>as</strong>e studies <strong>in</strong> cooperation with local<br />

growers (on-farm experiments).<br />

Consumers are not aware of how to<br />

select good quality (well poll<strong>in</strong>ated)<br />

fruits and vegetables<br />

Demonstration materials should be developed<br />

to help the consumer recognize and choose<br />

good quality products. Fruits and vegetables,<br />

such <strong>as</strong> melons, watermelons, apples and<br />

cucumbers, often have fewer than normal<br />

seeds, which results <strong>in</strong> <strong>in</strong>ferior products with a<br />

bad t<strong>as</strong>te. Such an awareness and educational<br />

programs will create a more sophisticated consumer<br />

and will encourage growers to use bees<br />

to produce high quality fruit.<br />

Other problems:<br />

• beekeepers generally are not concerned<br />

about determ<strong>in</strong><strong>in</strong>g the poll<strong>in</strong>at<strong>in</strong>g efficiency<br />

of their colonies, but are only try<strong>in</strong>g to produce<br />

the largest possible amount of honey;<br />

• beekeepers do not know how to stimulate<br />

the bees to collect pollen, which <strong>in</strong>cre<strong>as</strong>e<br />

poll<strong>in</strong>ation efficiency, <strong>in</strong>stead of nectar;<br />

• beekeepers do not know how to direct bees<br />

to a crop that needs poll<strong>in</strong>ation;<br />

• beekeepers distribute their beehives <strong>in</strong> a manner<br />

that is convenient for management, without<br />

concern or knowledge about the most<br />

efficient arrangement to facilitate poll<strong>in</strong>ation;<br />

• beekeepers manage their bees only for<br />

honey production because the farmers normally<br />

do not pay for poll<strong>in</strong>ation services;<br />

• we do not know the support capacity of<br />

agricultural are<strong>as</strong> for honey bee colonies or<br />

how many honey bee colonies can be<br />

placed <strong>in</strong> a specific area.<br />

Rear<strong>in</strong>g and management<br />

of Africanized honey bees<br />

<strong>in</strong> greenhouses<br />

Current problems:<br />

• lack of knowledge of the m<strong>in</strong>imum requirements<br />

necessary to use Africanized bees <strong>in</strong><br />

greenhouses (size of the colony, best time to<br />

<strong>in</strong>troduce the bees to the crop, culture<br />

specifics and management techniques);<br />

• misconceptions about Africanized bees <strong>as</strong><br />

effective <strong>poll<strong>in</strong>ators</strong>;<br />

• aggressiveness of the bees;<br />

• lack of technical and practical experience.<br />

Proposals:<br />

Workshop I 69<br />

• make producers aware of the usefulness of<br />

honey bees for poll<strong>in</strong>at<strong>in</strong>g <strong>in</strong> green houses;<br />

• <strong>in</strong>form public and private agencies <strong>in</strong>volved<br />

<strong>in</strong> rural extension, technical <strong>as</strong>sistance and<br />

promotion;<br />

• encourage research <strong>in</strong>stitutions to make<br />

studies on this subject, through specific<br />

guidel<strong>in</strong>es and f<strong>in</strong>anc<strong>in</strong>g;<br />

• develop <strong>in</strong>formative material, <strong>as</strong> a tool to<br />

encourage <strong>in</strong>cre<strong>as</strong>ed use of honey bees <strong>in</strong><br />

greenhouses, <strong>in</strong>form<strong>in</strong>g about successful<br />

experiences <strong>in</strong> <strong>Brazil</strong> and from other parts<br />

of the world, and by exam<strong>in</strong><strong>in</strong>g economic<br />

criteria;<br />

• develop <strong>in</strong>centives for us<strong>in</strong>g honey bees <strong>as</strong><br />

<strong>poll<strong>in</strong>ators</strong> <strong>in</strong> greenhouses and reduc<strong>in</strong>g the<br />

use of pesticides (tax deductions, low <strong>in</strong>terest<br />

loans, etc.);<br />

• publicity campaigns <strong>in</strong>form<strong>in</strong>g about the<br />

better quality of well-poll<strong>in</strong>ated fruits and<br />

vegetables, uncontam<strong>in</strong>ated by pesticides;<br />

• encourage and make available techniques<br />

for produc<strong>in</strong>g food <strong>in</strong> greenhouses;<br />

• capacitate technicians <strong>in</strong>volved <strong>in</strong> extension<br />

and who <strong>as</strong>sist farmers so that they can<br />

help them use honey bees <strong>as</strong> <strong>poll<strong>in</strong>ators</strong> <strong>in</strong><br />

greenhouses.
