4.Initiate a scientific journal on poll<strong>in</strong>ator<br />

biology <strong>in</strong> <strong>Brazil</strong>. <strong>Brazil</strong> h<strong>as</strong> many bee<br />

researchers, however much of the <strong>in</strong>formation<br />

is not readily available. A scientific<br />

journal will help remedy this problem and<br />

will help direct students and professors to<br />

study poll<strong>in</strong>ation problems. This journal<br />

could be produced onl<strong>in</strong>e at relatively low<br />

cost, and could help consolidate bee<br />

research <strong>in</strong> <strong>Brazil</strong>.<br />

5.Develop a manual on research techniques for<br />

poll<strong>in</strong>ator studies, especially to determ<strong>in</strong>e the<br />

value of <strong>poll<strong>in</strong>ators</strong> for crop production.<br />

Rational Program of Poll<strong>in</strong>ation<br />

1.Determ<strong>in</strong>e how well crops are poll<strong>in</strong>ated<br />

currently and <strong>in</strong>vestigate the production<br />

potential if there were full, adequate<br />

poll<strong>in</strong>ation. Some crops are already<br />

well poll<strong>in</strong>ated, and additional <strong>poll<strong>in</strong>ators</strong><br />

do not <strong>in</strong>cre<strong>as</strong>e production. In other crops<br />

and regions, there are so few natural <strong>poll<strong>in</strong>ators</strong><br />

that supplemental poll<strong>in</strong>ation can<br />

make the difference between uneconomical<br />

production and profit.<br />

2.Estimate economic viability of poll<strong>in</strong>ation<br />

program. The producer needs to have<br />

an idea about whether it will be economically<br />

viable to use poll<strong>in</strong>ation for his crop, consider<strong>in</strong>g<br />

the costs <strong>in</strong>volved with personnel,<br />

transport, and rent<strong>in</strong>g bee colonies, compared<br />

to the <strong>in</strong>cre<strong>as</strong>es <strong>in</strong> production.<br />

3.Identification of the requirements of the<br />

crop and determ<strong>in</strong>ation of the poll<strong>in</strong>ation<br />

needs. Each vegetal species h<strong>as</strong> its<br />

own specific poll<strong>in</strong>ation needs and appropriate<br />

poll<strong>in</strong>ation techniques are needed to fulfill<br />

these needs.<br />

4.Determ<strong>in</strong>e the poll<strong>in</strong>ation strategy that<br />

should be used. There is a need to determ<strong>in</strong>e<br />

the number of colonies per hectare,<br />

the arrangement and temporal placement<br />

of the colonies and <strong>in</strong>tegration with other<br />

cultural practices.<br />

5.Design and <strong>in</strong>stall apiaries and <strong>in</strong>fr<strong>as</strong>tructure<br />

necessary for poll<strong>in</strong>ation.<br />

Determ<strong>in</strong>e the number of apiaries and<br />

colonies that will be needed at appropriate<br />

times to give support to the poll<strong>in</strong>ation<br />

activities.<br />

6.Tra<strong>in</strong><strong>in</strong>g of personnel responsible for<br />

ma<strong>in</strong> ta<strong>in</strong><strong>in</strong>g the colonies <strong>in</strong> conditions<br />

ade quate for poll<strong>in</strong>ation. Prepar<strong>in</strong>g colo -<br />

nies for poll<strong>in</strong>ation requires specific management<br />

so that they will be at an adequate<br />

stage of development and with sufficiently<br />

large populations to adequately<br />

poll<strong>in</strong>ate the crop.<br />

7.Tra<strong>in</strong><strong>in</strong>g of personnel to collect poll<strong>in</strong>ation<br />

data <strong>in</strong> the field or hire such help. The<br />

results of poll<strong>in</strong>ation should be constantly<br />

monitored.<br />

F<strong>in</strong>al recommendations<br />

Consider<strong>in</strong>g what are the conservation me<strong>as</strong>ures<br />

necessary to keep a stable population of<br />

Africanized bees <strong>in</strong> the cropp<strong>in</strong>g are<strong>as</strong>:<br />

1.<strong>in</strong>centives, such <strong>as</strong> tax exemptions for beekeepers<br />

and for growers for poll<strong>in</strong>ation of<br />

crops <strong>in</strong> <strong>Brazil</strong>;<br />

2.PDF-B should make a policy of recogniz<strong>in</strong>g<br />

the need for Africanized bees for poll<strong>in</strong>ation;<br />

3.conduct c<strong>as</strong>e studies to show the importance<br />

of wild <strong>poll<strong>in</strong>ators</strong> <strong>in</strong> respective habitats;<br />

4.stop <strong>in</strong>discrim<strong>in</strong>ate logg<strong>in</strong>g and commercial<br />

fell<strong>in</strong>g of trees by enact<strong>in</strong>g laws;<br />

5.promote and encourage re-conversion of a<br />

certa<strong>in</strong> percentage of <strong>in</strong>tensively cultivated<br />

are<strong>as</strong> to provide rescue space for the multiplication<br />

of wild honey bee colonies by<br />

provid<strong>in</strong>g <strong>in</strong>centives (tax exemptions, subsidies<br />

etc.);
