Bottom Line: Three major findings included: (1) widespread use of the two compounds [of the 147 Phyllophaga (sensu stricto) species found in the United States and Canada, males of nearly 40% were captured]; (2) in most species intraspecific male response to the pheromone blends was stable between years and over geography; and (3) an unusual pheromone polymorphism was described from P. anxia.At additional locations, the L-valine methyl ester-responding populations and the L-isoleucine methyl ester-responding populations were both present, producing a bimodal capture curve.In southeastern Massachusetts and in Rhode Island, in the United States, P. anxia males were captured with blends of L-valine methyl ester and L-isoleucine methyl ester.

ABSTRACT
The sex pheromone of the scarab beetle, Phyllophaga anxia, is a blend of the methyl esters of two amino acids, L-valine and L-isoleucine. A field trapping study was conducted, deploying different blends of the two compounds at 59 locations in the United States and Canada. More than 57,000 males of 61 Phyllophaga species (Coleoptera: Scarabaeidae: Melolonthinae) were captured and identified. Three major findings included: (1) widespread use of the two compounds [of the 147 Phyllophaga (sensu stricto) species found in the United States and Canada, males of nearly 40% were captured]; (2) in most species intraspecific male response to the pheromone blends was stable between years and over geography; and (3) an unusual pheromone polymorphism was described from P. anxia. Populations at some locations were captured with L-valine methyl ester alone, whereas populations at other locations were captured with L-isoleucine methyl ester alone. At additional locations, the L-valine methyl ester-responding populations and the L-isoleucine methyl ester-responding populations were both present, producing a bimodal capture curve. In southeastern Massachusetts and in Rhode Island, in the United States, P. anxia males were captured with blends of L-valine methyl ester and L-isoleucine methyl ester.

i1536-2442-6-39-1-f96: P. hirtiventris ♂ catches

Mentions: Male trap captures are graphically illustrated in Figures 64–126. The figures are arranged alphabetically by Phyllophaga species. Within each species figure, graphs are arranged alphabetically by state or province abbreviation. The graphs demonstrate three general patterns of species-specific male responses to a particular blend or group of blends. The three general patterns are displayed in Figure 127. First, some species, such as P. vehemens, flew primarily to the 100/0 L-valine methyl ester/L-isoleucine methyl ester lure and were sensitive to increasing amounts of L-isoleucine methyl ester in the other blends, its presence significantly reducing captures1. P. congrua, however, had a broader response profile and was captured not only with the 100 % L-valine methyl ester lure, but also with blends containing 10%–20% L-isoleucine methyl ester (Figure 71). A similar situation was seen in responses of male P. hirtiventris (Figure 96). The second case (Figure 127) involved species such as P. forbesi that were captured primarily with the 100% L-isoleucine methyl ester lure. Increasing titers of L-valine methyl ester resulted in reduced or no captures2. In the third case (Figure 127), some species of Phyllophaga, such as P. glabricula, required the presence of both compounds before captures occurred3. An examination of these male- response curves reveals that, whereas certain species had a rather broad response range to the L-valine methyl ester/L-isoleucine methyl ester blends,4 others exhibited response curves occupying a narrower range of blends5.
