Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The field of invention relates to insect barrier structure, and more particularly pertains to a new and improved gypsy moth larvae barrier apparatus wherein the same is arranged for the prevention of access of gypsy moth larvae and other crawling insects to direct travel upwardly about a tree trunk for access to an associated tree. 
     2. Description of the Prior Art 
     Gypsy moth infestations have effected tree growth to limit, and in some instances destroy, the foliage of deciduous and coniferous trees. Serious infestations will destroy trees wherein barrier spraying has assisted resistance due to the application of such spray over a large area, as well as the trees. The cycle of a gypsy moth and larvae are such that the larvae crawl to the foliage adjacent portions of a tree. The instant invention attempts to overcome deficiencies of the prior art by providing a readily efficient barrier mounted to an associated tree trunk to prevent such traverse of the tree trunk. Examples of the prior art include U.S. Pat. No. 4,766,695 to Harlow utilizing a tree-protecting band formed of a flexible polymeric film utilizing an adhesive or elastomeric material layer on a surface and contact with a tree and coating the exterior surface of the tree with a gypsy moth toxin. 
     U.S. Pat. No. 4,223,007 to Spence, et al. sets forth a microbial insecticide for use in protection of trees. 
     U.S. Pat. No. 3,885,341 to Kuchenbecker, et al. sets forth a gypsy moth trap utilizing one-way ports mounted within a container for receiving an insect therewithin. 
     As such, it may be appreciated that there continues to be a need for a new and improved gypsy moth larvae barrier apparatus as set forth by the instant invention which addresses both the problems of ease of use as well as effectiveness in construction and in this respect, the present invention substantially fulfills this need.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 11 thereof, a new and improved gypsy moth larvae barrier apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     FIG. 1 illustrates a prior art gypsy moth larvae barrier structure, as set forth in U.S. Pat. No. 4,766,695, wherein the polymeric band of the invention 1 is mounted about a tree trunk 2 utilizing an adhesive or elastomeric interior surface and an exterior coating of an insecticide. 
     More specifically, the gypsy moth larvae barrier apparatus 10 of the instant invention essentially comprises a porous, fabric web 11 mounted continuously about a tree trunk to orthogonally align relative to an axis of the tree trunk. A mounting band 12 of an elastomeric or flexible construction is mounted about the web medially of the web to define a central web valley circumferentially directed about an exterior surface of the web defining an upper projecting barrier ridge 14 and a lower projecting ridge 15 to effect impediment to larvae attempting traverse of the web. 
     Further, the organization may optionally utilize a dispensing band 16 that is utilized and projected through a web top surface 37 (see FIG. 8) to provide supplemental projection of a pesticide or insecticide within the web 11. The band 16 may be provided by a spool 17 of such material and the band 16 severed from the spool of a length as desired dependent upon the circumferential dimension of an associated tree trunk 2. A plug member 19 contained within a plug member container 18 is utilized, wherein the plug member (see FIGS. 9-11) is directed within a complementarily configured central reservoir cavity 27 that is formed within a central body portion 24, to be described in more detail below. 
     Reference to FIGS. 5-8 illustrate the use of the dispensing band 16 that is formed to define a band trough 21 formed to a top surface of the dispensing band, wherein the trough 21 is defined between a rear wing 22 and a forward wing 23 that project upwardly to define the central band trough 21. The dispensing band includes the central body portion 24 that coextensively is formed with a first channel 25 that bisects an included angle defined by an intersection or junction defined by the rear and forward wings 22 and 23 and projects in communication with the band trough 21 into the first channel 25 that is coextensively formed throughout the body portion 24. Reference to FIG. 11 illustrates that a plurality of first channel entrance openings 36 directed into the top surface of the dispensing band 16 or the junction of the rear and forward wings is in communication with the first channel 25. The reservoir cavity 27 is filled with a pesticide powder 28, wherein a lower terminal end of the generally triangular cavity 27 includes a lower pointed end into fluid communication with a dispensing channel 29 that is aligned with the first channel 25, with the dispensing channel 29 projecting through a forward face of the dispensing band 16 adjacent a lower terminal pointed end 35. The lower body portion 30 of the dispensing band 16 is formed of a generally arrow shaped configuration, including rear and forward spur projections 31 and 32 that are directed rearwardly to enhance engagement of the dispensing band 16 within the web top surface 37. A first removable tape 26 is removably mounted overlying the plurality of the first channel entrance openings 36, with a second removable tape 33 removably mounted overlying the dispensing channel openings 34. During irrigation or accumulation of rain within the band trough 21, water is directed into the first channel entrance openings 36 and thereafter into the central reservoir cavity 27 to effect directing of an aqueous solution of pesticide or insecticide directed through the dispensing channel openings 34 into the body of the porous web 11. In this manner, the web is eventually and continuously metered with the insecticide to further inhibit traverse of various insects thereacross. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
