    There are three types of bees
+
living in a beehive: the worker

bees, the queen bee and the male
+
bees. In the colony, the work is
+
divided in such a way that each
+
caste is specialized in its activities.
+
The worker bees are infertile female
+
and represent the most numerous caste
+
in the beehive. Their main activities are
+
to clean the beehive cells, ventilate the
+
beehive, cap the beehive cells containing
+
the bee eggs, feed the larvae, gather pollen and defend the colony.

Their main activity is the reproductive function with the queen bee outside of  the beehive.

Over the last few decades, a decline in the honeybee population has been observed. In Europe 24%
 
of the domestic bee species are threatened of extinction. The more indicators you consider, the
 
more alarming the situation appears. Bee loss has a multifactorial origin. Among these factors,
 
the <b>Colony Collapse Disorder</b> (CCD) is one of the most important. CCD corresponds to a massive loss
 
of bee colonies. The causes of this syndrome are numerous: pesticides, viruses, parasites… among those,
 
a mite wisely named <!-- ANCHOR varroa --> <i id="varroa">Varroa destructor</i> is one of the bees fiercest enemies.

<h3><i>Varroa destructor</i></h3>

  <div class="group center"> <!-- FIRST PARAGRAPH -->
 
        <p align="justify" style="font-size:15px;">
 
 
<i>Varroa destructor</i> is an obligatory ectoparasite
 
of bees. This means it is an external parasite
 
and it cannot survive without its host, the bee.
 
The varroa development cycle takes place in the
 
beehive cells in parallel of the bee development
 
cycle. The key individual of the varroa development
 
cycle is the adult female commonly named “founder”.
 
The founder reproduces exclusively in a brood cell
 
that represents the beehive cell containing a bee
 
larva. The founder reproduction occurs during the
 
phoretic phase where the varroa is moved from one
 
bee colony to the other by an adult bee.

The bee infestation by varroa occurs between the egg laying of the queen bee in beehive cells and the encapsulation of the bee larva inside the beehive cell. After feeding off the larva the founder will start laying varroa eggs. The newborn varroas will develop themselves, go through different stages and will reproduce within the brood cell.
+
When the mature bee finally emerges from the brood cell, female varroas will stick themselves to it therefore becoming “phoretic”.
+
The <i>Varroa destructor</i> itself is of significant danger. However it is the association with the Deformed Wing Virus (DWV) that makes him one of the most virulent threats for honeybees. The study of the interplay between the mite and the DWV shows that an intense viral replication is triggered by the mite feeding off the bee, leading to a devastating viral outbreak.

The mite varroa was originally an ectoparasite
 
of <i>Apis cerana</i>, the Asian honey bee. The first
 
contact between varroa and <i>Apis mellifera</i>
 
occurred in the 1950s in Asia. During the
 
following years, the infestation spread to
 
Europe, Africa and America. The first signs
 
of this infestation were observed in Europe
 
and North America in the early 1980s.
 
The varroa mite is a particularly virulent
 
parasite of Apis mellifera since the European
 
honeybee did not have time to develop an adaptive
 
response to it. </p> <!-- ANCHOR fight--> <div id="fight"></div>   <p align="justify" style="font-size:15px;">In Asia on the contrary, <i>Apis cerana</i>
 
and <i>Varroa destructor</i> co-evolved over the centuries
 
and reached a certain balance. Interestingly, the Asian
 
honeybee is capable of detecting the parasite’s presence
 
and getting rid of it.

This last type is the most effective, however it is limited and their

use is complicated since bees generate consumable

products. The lack of effectiveness of those treatments allows enough varroa to decrease

bee population in hives, beyond dangerous thresholds. The use of such treatments (usually yearly) can eliminate
+
up to 90% of the varroa population,
+
which is insufficient to maintain the plague at safe levels.<br><br>
+
On top of that, such treatments may have serious disadvantages:

Furthermore, at the moment, beehives are only treated with formic acid during <b>spring</b> and <b>fall</b>, when no

honey is being made. This is due to the fact that formic acid weakens bees, but also that when varroa have entered the

brood, they are <b>not affected by the miticide</b>. <br>
+
The attraction power of ApiColi will enable us to prevent most varroas from entering the beehive and reaching the brood.

This way, our treatment would be <b>usable</b> even <b>during summer</b>.

With our project, we want to protect bee colonies from infestation by <i>Varroa destructor</i>. To achieve the establishment of the balance between the mite and honey bees, we need to <b>attract varroas prior their entrance in the beehive</b>, and to kill them. The molecules we chose to do so are butyric acid and formic acid (<i>See sections Attract and Eradicate</i>).
 
Indeed it was shown that <b>butyric acid</b> is one of the molecules produced by bee's larvae in the brood and has an <b>attractive power</b> towards varroas (based on the Patent <i>Methods for attracting honey bee parasitic mites</i>, US 8647615 B1).

Concerning <b>formic acid</b>, it is currently used by beekeepers as a treatment against varroa infestation but only during spring and fall and at high doses. Thus it has deleterous effects on bees and beekeepers.
+
/* Latest Work */
We also know that bees have a lifecycle based on the sunlight. As we explain above, during the day, bees are active and come in and out of the hive to gather pollen. This is when they bring back the varroas to the hive. During the night on the contrary, bees are less active and stay in the hive.

With all these data, we have been able to design a perfect solution fighting <i>Varroa destructor</i>. A trap containing the engineered bacteria (ApiColi) will be placed at the entrance of the beehive. <b>During the day</b>, Apicoli will <b>produce butyric acid</b> which will diffuse up to where the bees enter the hive. The varroas will be attracted and drop into the trap through a grid. Thus they will never come inside the hive.
+
.boxedicon a:hover{color:#FFFFFF;}

</div>

+
<div class="group center">
+
<p class="text">
+
To be respectful of the bees lifecycle, our bacteria will only <b>produce formic acid at night</b>. This way, the bees will be much less exposed to it since it will be confined to the trap and at much lower doses.
+
Finally, we do not know if these two molecules effect can interfere, but we do know that they can be harmful to ApiColi if accumulated. That is why alternating production of both acids according to a circadian rhythm will enable us to have a more controlled use of the carbon source, and thus a longer culture length and trap efficiency.
+
<br>
+
To do so, based on a paper published in Nature by Levskaya et al., Synthetic biology: engineering <i>E. coli </i> (2005), we used a <b>light switch system </b> composed of two membrane proteins:</p>
