<p class="MsoNormal"><span style="font-family:"Arial Narrow","sans-serif";color:#595959">Hi Craig,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial Narrow","sans-serif";color:#595959"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial Narrow","sans-serif";color:#595959">Aphid related calls make up approximately 90% of all public IPM service requests received by our Program each year. Over the years, we have tried a number of different
strategies to address this issue such as the release of Ladybird beetles, Orthene injection trials, educational campaigns etc. Among all of our efforts, we found the most successful means to address this issue is by responding to the caller in a quick and
proactive manner. While we do have information on the City’s website, we don’t provide any hard copy information directly to callers. Here’s the link for information about aphids and City trees on our website:
<a href="http://www.surrey.ca/community/11591.aspx">http://www.surrey.ca/community/11591.aspx</a>
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial Narrow","sans-serif";color:#595959">Our current method to address aphid calls comprises of a combination of monitoring and soap sprays by an IPM contractor. All calls are received and vetted by our lead IPM
staff arborist. Calls such as “I want my tree sprayed” or “My tree is dripping sap” are directly sent to our contractor who will make contact with the caller within 24hours. If the issue has met the City thresholds, then at the time of their initial site visit
the tree is posted for a soap spray the following day. An additional spray is then scheduled within 7 to 10 days. Severe cases or repeat callers are then put on a monitoring schedule in the event a second two-part spray is needed. The only calls staff will
address internally are callers who are fed up and have requested to have the tree removed or drastically pruned. We feel that in these situations, it is preferable to have staff respond to help placate the issue.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial Narrow","sans-serif";color:#595959">Our monitoring process is based on the severity of ‘honey dew’ rather than an aphid count. The reality with these calls is that we are dealing with the resident’s threshold
rather than the tree; we found the following metric a better alternative for tracking and generating control measures.
<o:p></o:p></span></p>
<p class="MsoNormal"><u><span style="font-family:"Arial Narrow","sans-serif";color:#595959">Honeydew Levels<o:p></o:p></span></u></p>
<p class="MsoNormal"><span style="font-family:"Arial Narrow","sans-serif";color:#595959">0.0 - none<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial Narrow","sans-serif";color:#595959">0.5 - very low<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Arial Narrow","sans-serif";color:#595959"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial Narrow","sans-serif";color:#595959">This year we are exploring the use of repeat high pressure water sprays to help control aphid populations. So far we are seeing some effectiveness with these trial sprays.

<p class="MsoNormal">I would like to ask for some advice from as it pertains to the management of Aphids populating City trees and how Municipalities respond to the public to address the concerns that are a result of the honeydew? After the extended dry and
hot summer we experienced last year we have had a real increase in the public’s concern of Aphids with the most susceptible trees being Linden, Tulip Trees and Red Oak. As a result our Parks Management team has requested that we put together an informative
fact sheet to provide the public that explains the life cycle of Aphids , our maintenance procedures as it relates to IPM and city by-laws, as well as the benefits of using beneficial insects to achieve acceptable thresholds.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If some of you could share any information or strategies used it would be greatly appreciated.<o:p></o:p></p>
