“…Such variation in the adults could result from interactions among various factors such as adult age, sex, and nutritional status. Considering that the age of the adults tested was homogeneous and sex was not a signiÞcant factor, the nutritional status during the im- mature stages (often measured by body size or weight) might be one of the most contributing factors to this variation (Scriber and Slansky 1981;Brodbeck et al 1995Brodbeck et al , 2004. Nonetheless, the variation was adequately quantiÞed by using the Weibull model in this study, and it is a key component to building realistic life history models (Sharpe et al 1981, Ré gniè re 1984.…”

Survival of the glassy-winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), was studied under various constant temperatures and feeding conditions. When provided a host plant (Citrus limon L. Burm. f.) to feed on during a 21-d trial, 100% mortality occurred at 0.1, 3.2, and 40.1 degrees C, whereas an average of 74-76% of adults survived in the 13.2-24.5 degrees C range. When individually confined with moist cotton, adult longevity was greatest (16.3 d) at 13.3 degrees C, but it was <3 d at -2.4 and 36.2 degrees C. In a companion study comparing the presence versus absence of a host plant, the presence of a host plant was not a significant factor influencing survival at temperatures < or =7.8 degrees C but was at temperatures > or =18.9 degrees C. The relationship between temperature and survival was described by a nonlinear function that estimated the optimum temperature in each feeding regimen: no host plant or moist cotton (5.5 degrees C), moist cotton (9.9 degrees C), and accessible host plant (25.1 degrees C). The model quantitatively predicted that H. vitripennis would survive longer periods at a wider temperature regimen when provided with a host plant than when provided with water alone (moist cotton) or when provided with neither plant host nor water. Our results suggest that continuous exposure to either low (<5 degrees C) or high (>30 degrees C) temperatures are detrimental for adult survival. Specifically, low temperatures caused early mortality because of inhibition of feeding activity and presumably this threshold lies between 7.8 and 13.2 degrees C. Furthermore, this study clearly shows that temperature may influence the survival of H. vitripennis adults regardless of feeding regimens, and its implications for population dynamics are discussed.

“…The preference and performance of H. coagulata on other host species have been shown to vary with host plant chemistry (Brodbeck et al 1990(Brodbeck et al , 1999(Brodbeck et al , 2004. Cultural conditions such as irrigation and fertilization also inßuence xylem ßuid chemistry (Andersen and Brodbeck 1989a, b, 1991, Andersen et al 1995a, which may impact H. coagulata feeding and performance (Andersen et al 1992, Brodbeck et al 1999.…”

“…Moreover, insects that feed on xylem fluid provide a model system for examination of effects as organic nitrogen in xylem fluid is predominantly in amino acid form and the fluid is depauperate of secondary compounds. Essential amino acids have previously been shown to be critical to the performance (growth and development) of immature H. vitripennis (Brodbeck et al 1995(Brodbeck et al , 1996(Brodbeck et al , 2004, and also correlated to abundances of immature H. vitripennis in the field (Bi et al 2007). Recent studies under controlled conditions suggest that essential amino acids may also be the basis for adult performance (Brodbeck et al 2007).…”

“…Glutamine and amides are the predominant forms of organic nitrogen found in the xylem fluid of many, if not most, woody plant species (Pate 1980). They are also often positively correlated with essential amino acids in many, but not all plant species (e.g., Andersen et al 1992;Brodbeck et al 2004;Bi et al 2005Bi et al , 2007. In the xylem fluid of Prunus, glutamine accounts for less than 20% of the total organic nitrogen.…”

“…Diurnal feeding patterns for Cicadellinae have been shown to mirror circadian fluctuations in xylem chemistry (Brodbeck et al 1993). Xylem nutrients have also been shown to be well-correlated with the performance of developing nymphs (Brodbeck et al 1995(Brodbeck et al , 2004(Brodbeck et al , 2007Bi et al 2007) as well as adult leafhoppers (Brodbeck et al 2007). Allocation of ingested nutrients may directly influence reproduction, body size and body composition for adult H. vitripennis as adults are long-lived (typically up to 4 months; Sisterson 2008) and feed copiously, gain body mass, and maintain high fecundity months after reaching maturity (Andersen et al 1989(Andersen et al , 1992Brodbeck et al 1995).…”

Nutrient mediation of behavioral plasticity and resource allocation in a xylem-feeding leafhopper

Phenotypic plasticity may be critical for nutrient-limited organisms that allocate ingested nutrients to the competing demands of reproduction and survivorship. Leafhoppers that feed on xylem fluid allow assessment of plasticity in response to the constant selective pressure of nutritional inadequacy. We examined feeding behavior (host selection and consumption rates) and nutrient allocation (fecundity, change in body mass and composition) of the xylem fluid-feeding leafhopper Homalodisca vitripennis (Hemiptera:Cicadellidae) on ten genotypes of related Prunus germplasm when adults first seasonally appear, and later during population peaks, to examine the effects of genotypes and season on plasticity of life history and behavioral traits. Behavior and resource allocation to life history traits were both mediated by xylem nutrients, although nutrients impacting behavior differed from those mediating life history. Host selection and consumption varied with genotype between June and July, yet behavior consistently reflected concentrations of dietary glutamine. Resource allocations also increased linearly with nutrient concentrations, but were best correlated to ingested essential amino acids rather than glutamine. Body mass and composition were highly correlated to dietary essential amino acids in June; 6 weeks later, fecundity was instead proportional to essential amino acids. The discrepancy in nutrients which impact behavior versus those mediating life history may explain the weak preference-performance linkage documented for many insects. The demarcation in allocating resources to biomass in June to fecundity in July suggests increased allocation to reproduction during periods of nutrient stress as predicted by the theory of optimal resource allocation; other contributing biotic and abiotic factors are also discussed.
