“…Similar to some earlier studies (e.g. [30][31][32] ), high CI was frequently associated with high ECI. Oenopia conglobata contaminata and H. variegata had the highest CI when fed on psylla and aphid diets, respectively.…”

Where both the psyllids and the aphids occur in pistachio orchards, especially under conditions of unlimited access to A. gossypii, C. undecimpunctata aegyptica, H. variegata and E. nigripennis may prefer to move from psylla-infested leaves of pistachio trees and travel to and stay on weeds to feed on A. gossypii. The value of using nutritional ecology as a means of understanding and predicting biocontrol outcomes and selecting better candidates for mass rearing is discussed. © 2018 Society of Chemical Industry.

“…Essential and alternative food sources have only been categorized comprehensively for a few intensively studied species. Although individuals show decreased fecundity or increased mortality in the laboratory when fed solely on alternative prey (Hodek & Honek, 1996; Jalali et al. , 2009), an ability to prey on alternative species allows individuals to survive for longer periods without essential prey (Hodek & Michaud, 2008).…”

ABSTRACT AimDetermining to what extent differing distribution patterns are governed by species' life-history and resource-use traits may lead to an improved understanding of the impacts of environmental change on biodiversity. We investigated the extent to which traits can explain distribution patterns in the ladybird fauna (Coleoptera: Coccinellidae) of Great Britain. LocationThe British mainland and inshore islands (Anglesey, the Isle of Wight and the Inner Hebrides).Methods Distributions of 26 ladybirds resident in Britain were characterized in terms of their range size (from 2661 10-km grid-squares across Britain) and proportional range fill (at 10-and 50-km scales). These were assessed relative to five traits (body length, elytral colour pattern polymorphism, voltinism, habitat specificity and diet breadth). The role of phylogenetic autocorrelation was examined by comparing the results of phylogenetic and generalized least-squares regressions.Results Diet breadth was the only trait correlated with range size: species with broad diets had larger range sizes than dietary specialists. Range fill was sensitive to the average recording intensity of a species across inhabited squares; models including both recording intensity and range size provided more explanatory power than models incorporating ecological traits alone. Main conclusionsHabitat specificity is often invoked to explain the distribution patterns of species, but here we found diet breadth to be the only ecological correlate of both range fill and range size. This highlights the importance of understanding predator-prey interactions when attempting to explain the distribution patterns of predatory species. Our results suggest that the diet breadth of predatory species is a better correlate of range size and fill than other measures such as habitat specificity.

Mating stimulates female feeding: testing the implications for the evolution of nuptial gifts

Nutritional benefits from nuptial gifts have been difficult to detect in some species, raising the question: what maintains nuptial feeding when gifts do not benefit females? The sensory trap hypothesis proposes that nuptial feeding may be explained by pre‐existing sensory responses that predispose females to ingest gifts. Recent studies have shown that male seminal proteins can induce a nonspecific increase in female feeding after mating, which may represent a sensory trap for nuptial feeding if it results in increased intake of post‐mating gifts. I tested these ideas using female beetles that ingest a spermatophore after mating. I show that males stimulate strongly increased female feeding post‐mating. However, there was little evidence for dose dependence in the feeding response that could allow males to stimulate feeding beyond the female optimum. Moreover, the post‐mating feeding response could not explain nuptial feeding: despite feeding more in general, newly mated females were less likely than nonmated females to ingest spermatophore gifts.
