Insects:

 

Aphids     Asian Longhorned Beetle
 


Aphids feed by sucking up plant juices through a food channel in their beaks. At the same time, they inject saliva into the host. Light infestations are usually not harmful to plants, but higher infestations may result in leaf curl, wilting, stunting of shoot growth, and delay in production of flowers and fruit, as well as a general decline in plant vigor. Some aphids are also important vectors of plant diseases, transmitting pathogens in the feeding process.

A sticky glaze of honeydew may collect on lower leaves, outdoor furniture, cars, and other objects below aphid feeding sites. Honeydew coated objects soon become covered by one or more brown fungi known as sooty molds. Crusts of sooty mold are unsightly on man-made objects, and they can interfere with photosynthesis in leaves.

The Asian longhorned beetle (ALB) is an exotic pest threatening a wide variety of hardwood trees in North America. Adults are large (0.75 - 1.50 inches long) with very long black and white banded antennae.  The body is glossy black with irregular white spots.  Adults can be seen from late spring to fall depending on the climate.

ALB attacks and kills many hardwood trees, such as maple, elm, horsechestnut, ash, birch, poplar, willow and many more.  ALB could significantly disrupt the forest ecosystem if it became established over a large area.

Diseases:

 

Wetwood (slime flux)    
 

 

Bacterial wetwood, also called slime flux, is a major bole rot of trunk and branches of trees. Slime flux has been attributed to bacterial infection in the inner sapwood and outer heartwood area of the tree.

A tree with slime flux is water-soaked and "weeps" from visible wounds and even from healthy looking bark. The "weeping" may be a good thing as it is having a slow, natural draining effect on a bacterium that needs a dark, damp environment. A tree with this bole rot is trying its best to compartmentalize the damage.
