Allee effects in a Ricker-type predator-prey system [PDF]

open access: yesarXiv, 2014
We study a discrete host-parasitoid system where the host population follows the classical Ricker functional form and is also subject to Allee effects. We determine basins of attraction of the local attractors of the single population model when the host intrinsic growth rate is not large.

Determinants of mating success in a lek‐mating species

open access: yesAgricultural and Forest Entomology, EarlyView.
Abstract Leks are male‐biased aggregations formed for mating, where sperm is the only resource acquired by visiting females. One of the many advantages of leks is the possibility to efficiently assess the quality of potential mates by comparing aggregated individuals of the same sex with one another. When direct mate choice occurs in a lekking species,

The temperature affects the impact levels of synthetic insecticides on a parasitoid wasp used in the biological control of pentatomid pests in soybean crops [PDF]

open access: yesarXiv
The impact of climate change has led to growing global concern about the interaction of temperature and xenobiotics in agricultural toxicological studies. Thus, for the first time, we evaluated the lethal, sublethal and transgerational effects of six insecticides used in the management of stink bug complex in soybean crops on the different life stages ...
