Information processing by herbivorous insects can impair the accuracy of decision‐making during host‐plant selection. Consequently, insects with a narrower diet breadth are expected to be more accurate decision‐makers, as they cope with a smaller set of relevant stimuli.

Counties not countries: Variation in host specificity among populations of an aphid parasitoid
Parasitic wasps are among the most species‐rich groups on Earth. A major cause of this diversity may be local adaptation to host species. However, little is known about variation in host specificity among populations within parasitoid species.

Parasitoid wasp usurps its host to guard its pupa against hyperparasitoids and induces rapid behavioral changes in the parasitized host. [PDF]
Some parasites have an ability to fabricate the behavior of their host and impel the host to guard parasites' offspring, which is popularly called as bodyguard manipulation.

Global redistribution and local migration in semi-discrete host-parasitoid population dynamic models [PDF]
Host-parasitoid population dynamics is often probed using a semi-discrete/hybrid modeling framework. Here, the update functions in the discrete-time model connecting year-to-year changes in the population densities are obtained by solving ordinary differential equations that mechanistically describe interactions when hosts become vulnerable to ...

A Comparative Analysis of Host--Parasitoid Models with Density Dependence Preceding Parasitism [PDF]
We present a systematic comparison and analysis of four discrete-time, host--parasitoid models. For each model, we specify that density-dependent effects occur prior to parasitism in the life cycle of the host. We compare density-dependent growth functions arising from the Beverton--Holt and Ricker maps, as well as parasitism functions assuming either ...

Natural parasitism of the Citrus Leafminer (Lepidoptera: Gracillariidae) over eight years in seven citrus regions of São Paulo, Brazil [PDF]
The citrus leafminer (CLM) Phyllocnists citrella Stainton (Lepidoptera: Gracillariidae) was frst recorded in Brazil in 1996. In 1998, the parasitoid Ageniaspis citricola Logvinovskaya (Hymenoptera: Encyrtdae) was introduced and established in many ...

With increasing demand for sustainable goods, botanical dyes are of increasing interest and value to consumers, industry and small‐scale artisanal producers. Goldenrod is a widely used dye plant with a long history of traditional use. The impact of the well‐studied goldenrod stem gall produced by Eurosta solidaginis on goldenrod botanical dyes—and the ...

Host-feeding enhances stability of discrete-time host-parasitoid population dynamic models [PDF]
Discrete-time models are the traditional approach for capturing population dynamics of a host-parasitoid system. Recent work has introduced a semi-discrete framework for obtaining model update functions that connect host-parasitoid population levels from year-to-year.

The $P^*$ rule in the stochastic Holt-Lawton model of apparent competition [PDF]
In $1993$, Holt and Lawton introduced a stochastic model of two host species parasitized by a common parasitoid species. We introduce and analyze a generalization of these stochastic difference equations with any number of host species, stochastically varying parasitism rates, stochastically varying host intrinsic fitnesses, and stochastic immigration ...

Impact of urbanization on predator and parasitoid insects at multiple spatial scales [PDF]
Landscapes are becoming increasingly urbanized, causing loss and fragmentation of natural habitats, with potentially negative effects on biodiversity. Insects are among the organisms with the largest diversity in urbanized environments.
