OUR NATIVE TERMITES — SNYDER 505 



One fungus, Lentinus lejndeus^ produce metabolites (end prod- 

 ucts) that appear to be very toxic to termites. Lemites trabea pro- 

 duces an attractant. Poria incrassata extended the laboratory life 

 considerably. Poria monticola exhibited a somewhat repellent effect. 

 Still other fungi seem to be neutral in eifect. At least one of the com- 

 mon molds {Penicillium spp,, Aspergillus spp., etc.) reduced the 

 longevity and the termites' death followed shortly. 



As yet some of these relationships are not supported by laboratory 

 or field evidence.
