“…Adult psyllids were examined daily over the 2Ð3 d preceding the establishment of female/male pairs and assigned to one of two color categoriesÑ gray/brown or blue/greenÑ based on the color of the ventral side of the abdomen (see Wenninger and Hall 2008a). Orange/yellow abdominal color, which is associated with the production of eggs and (in older males) the visibility of internal reproductive organs (Wenninger and Hall 2008a), is not considered in the current investigation.…”

“…Previously, Wenninger and Hall (2008a) showed that gray/brown individuals of both sexes in D. citri have lower body mass relative to blue/green individuals and found suggestive evidence of lower reproductive output in gray/brown females. In the present investigation, we directly examine whether female fecundity and egg fertility are related to female and male abdominal color.…”

“…Based on previous work (Husain and Nath 1927, Skelley and Hoy 2004, Wenninger and Hall 2008a, we recognize three more or less discrete color classiÞcations in the abdominal color of adult D. citri: gray/brown, blue/green, and orange/yellow. Abdominal color in D. citri may change over the life of an individual (Wenninger and Hall 2008a) and thus seems not to represent morphotypes that are exclusively determined genetically or seasonal morphotypes as are found in many sternorrhyncan species in more temperate climates.…”

Diaphorina citri Kuwayama (Hemiptera: Psyllidae), a vector of huanglongbing (citrus greening disease), exhibits three more or less distinct abdominal colors in the adult stage: gray/brown, blue/green, and orange/yellow. A previous report showed that, relative to blue/green individuals, gray/brown individuals of both sexes have lower body mass, and gray/brown females may have lower reproductive output. In the present investigation, we directly examined the relationships between female and male abdominal color and reproductive output. We also assessed how psyllid body mass was inßuenced by transfer to fresh plant material and how female and male abdominal color affected behavioral responses of males to crushed females in a petri dish assay. Relative to blue/green females, gray/brown females exhibited lower fecundity over the Þrst 2Ð5 d after mating, but fecundity did not differ over the remainder of a 21-d observation period. Regardless of abdominal color, females mated with gray/brown males showed an earlier, sharper peak in fecundity, whereas females mated with blue/green males showed a later, more gradual peak in fecundity. Gray/brown males elicited lower egg fertility in their mates, but egg fertility did not vary according to female abdominal color. MalesÑirrespective of abdominal colorÑ exhibited stronger evidence of attraction to crushed blue/ green females than to crushed gray/brown females. Gray/brown individuals of both sexes showed an increase in body mass 5Ð 6 d after transfer to a new citrus seedling, suggesting that abdominal color (which is closely related to body mass) may be inßuenced at least in part by plant quality.

“…Color morphs of ACP were classified as either blue/green or gray/brown 119 based on the abdominal color of newly emerged adults (Wenninger & Hall, 2008). Many ACP 120 possessed yellow ova or reproductive structures on the blue/green or gray/brown abdomens, yet 121 this color was not considered in the analysis as it occurs on both male and females and is thought 122 to be related to the age of the ACP (Wenninger et al, 2008). All ACP samples were measured 123 after mounting the body, right forewing and tibia onto glass slides using 10% bovine serum 124 albumin solution.…”

The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, is one of the most serious citrus pests worldwide due to its role as vector of huanglongbing or citrus greening disease.While some optimal plant species for ACP oviposition and development have been identified, little is known of the influence of host plants on ACP size and shape. Our goal was to determine how size and shape of ACP wing and body size varies when development occurs on different host plants in a controlled rearing environment. ACP were reared on six different rutaceous species; Bergera koenigii, Citrus aurantifolia, Citrus macrophylla, Citrus maxima, Citrus taiwanica and Murraya paniculata. Adults were examined for morphometric variation using traditional and geometric analysis based on 12 traits or landmarks. ACP reared on C. taiwanica were consistently smaller than those reared on the other plant species. Wing aspect ratio also differed between C. maxima and C. taiwanica. Significant differences in shape were detected with those reared on M. paniculata having narrower wings than those reared on C. macrophylla. This study provides evidence of wing size and shape differences of ACP based on host plant species which potentially may impact dispersal. Further study is needed to determine if behavioral and physiological differences are associated with the observed phenotypic differences. 63Morphometric analysis provides a tool to evaluate phenotypic variation that results from 64 a range of biotic and abiotic factors (Daly, 1985). Traditional morphometric analysis of size and 65 size ratios has been the classical approach for quantifying variation in biological specimens. It is 66 used to determine instar, and to compare genetic, environmental and phenotypic variation (Daly, 67 1985). A newer approach, geometric morphometric analysis, provides a mechanism to evaluate 68 shape independent of size through the use of landmarks on two-and three-dimensional surfaces , 1990; Bookstein, 1991 Bookstein, , 1996 Rohlf & Marcus, 1993;Dryden & Mardia, 1998).70 Geometric morphometric analysis has provided insight into patterns of morphological variation 71 associated with Musca domestica L. wild populations and laboratory colonies (Ludoški et al.,72 2014), wild sandfly populations (Santos et al., 2015), the discrimination of four species of Culex 73 mosquitoes (Laurito et al., 2015) and synonymy of two Bactrocera species (Schutze et al., 2015).74 Geometric morphometric analysis has also been instrumental in visualizing and comparing

“…Green-blue color morphs are known to have greater fitness, with greater fecundity, greater flight capability, greater mass, and greater resistance to insecticides compared with other color morphs (Wenninger & Hall 2008;Wenninger et al 2009;Tiwari et al 2013;Martini et al 2014). It is therefore possible that the green-blue morphotype of D. citri has the greatest potential for infesting new flush in the spring.…”
