“…If leaf size, phenolics and the presence of conspecifics are not affecting female oviposition behaviour, what cues – if any – could then be guiding female choice? In addition to the leaf traits investigated in this study, numerous chemical and physical properties of leaves, such as their nutritional value and toughness, could influence patterns of oviposition (Valladares & Lawton 1991; Derridj et al . 1996; Nieminen et al .…”

Summary1. According to the preference-performance hypothesis, female insects select resources that maximize offspring performance. To achieve high fitness, leaf miner females should then adjust their oviposition behaviour in response to leaf attributes signalling high host quality. 2.Here we investigate resource selection in Tischeria ekebladella , a leaf-mining moth of the pedunculate oak ( Quercus robur ), in relation to two alternative hypotheses: (1) females select their resources with respect to their future quality for developing larvae; or (2) temporal changes in resource quality prevent females from selecting the best larval resources. 3. Specifically, we test whether females show the strongest selection at the levels at which quality varies the most (shoots and leaves); whether they respond to specific leaf attributes (leaf size, phenolic content and conspecific eggs); and whether female preference is reflected in offspring performance. 4. Female choice of leaves was found to be non-random. Within trees, the females preferred certain shoots, but when the shoots were on different trees the degree of discrimination was about four times larger than when they were on the same trees. 5. While females typically lay more eggs on large leaves, this is not a result of active selection of large leaves, but rather a result of females moving at random and ovipositing at regular intervals. 6. The females in our study did not adjust their oviposition behaviour in response to leaf phenolic contents (as measured by the time of larval feeding). Neither did they avoid leaves with conspecific eggs. 7. Female choice of oviposition sites did not match patterns of offspring performance: there was no positive association between offspring survival and counts of eggs. 8. We propose that temporal variation in resource quality may prevent female moths from evaluating resource quality reliably. To compensate for this, females may adopt a risk-spreading strategy when selecting their resources.

“…The observed response of oviposition behavior to selection, at least within the pgm population, indicates that females can distinguish between the two mutants. Whether moths were responding to levels of nutrients in (or on) the plants (28)(29)(30) or to correlated differences in plant secondary chemistry (31) is not known.…”

Failure to adapt to a changing nutritional environment comes at a cost, as evidenced by the modern human obesity crisis. Consumption of energy-rich diets can lead to obesity and is associated with deleterious consequences not only in humans but also in many other animals, including insects. The question thus arises whether animals restricted over multiple generations to high-energy diets can evolve mechanisms to limit the deposition of adverse levels of body fat. We show that Plutella xylostella caterpillars reared for multiple generations on carbohydrate-rich foods (either a chemically defined artificial diet or a high-starch Arabidopsis mutant) progressively developed the ability to eat excess carbohydrate without laying it down as fat, providing strong evidence that excess fat storage has a fitness cost. In contrast, caterpillars reared in carbohydrate-scarce environments (a chemically defined artificial diet or a low-starch Arabidopsis mutant) had a greater propensity to store ingested carbohydrate as fat. Additionally, insects reared on the low-starch Arabidopsis mutant evolved a preference for laying their eggs on this plant, whereas those selected on the high-starch Arabidopsis mutant showed no preference. Our results provide an experimental example of metabolic adaptation in the face of changes in the nutritional environment and suggest that changes in plant macronutrient profiles may promote hostassociated population divergence.geometric framework ͉ nutrition ͉ Plutella

“…Insects probably detected chemicals on the surfaces of leaves and used them as cues for feeding and oviposition (Fiala et al, 1990;Derridj et al, 1996). Mann et al (2012) found that Las-infected citrus plants had lower levels of nitrogen, phosphorus, sulfur, zinc, and iron and higher levels of potassium and boron than uninfected plants.…”

Differences in Selection Behaviors and Chemical Cues of adult Asian Citrus Psyllids, Diaphorina citri, on Healthy and Huanglongbing-Infected Young Shoots of Citrus Plants

The pathogen Candidatus Liberibacter asiaticus (Las) causes devastating citrus huanglongbing in many parts of Asia. The host selection behavior of the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Sternorrhyncha: Psyllidae), the only known Las vector, is critical to its epidemics. Las-infected citrus plants attract adult psyllids by altering their color and chemical cues. However, it is unclear whether any changes in selection behavior or chemical cues occur in young shoots. Selection behavior bioassays showed the number of adults and eggs on Las-infected shoots was significantly higher than on healthy shoots. Significantly more adults responded to the odor of Las-infected shoots than to that of uninfected shoots. GC-MS analysis of volatile constituents showed that the quantitatively dominant constituents were β-elemene and β-phellandrene in both samples, (+)-epi-bicyclosesquiphellandrene was only detected in Las-infected shoots, but ocimene, germacrene D, δ-cadinene, d-longifolene, and α-sinensal were detected only in healthy shoots. Analysis of the concentrations of surface-soluble carbohydrates indicated that the levels of sucrose, fructose, and glucose were significantly higher on the surfaces of Las-infected shoots than on the surfaces of healthy shoots. Alteration of volatile compounds and soluble surface carbohydrates of young shoots after Las infection could be attributed to the preference of Asian citrus psyllids for Las-infected young shoots. The knowledge obtained from this investigation may contribute to novel control measures for plant diseases transmitted by insect vectors.
