Abstract Lethal and sublethal effects of pesticides on nontarget organisms are one of the causes of the current decline of many insect species. However, research in the past decades has focused primarily on pollinators, although other beneficial nontarget organisms such as parasitic wasps may also be affected.

A Wolbachia‐free Aedes albopictus strain was developed and considered to be used for SIT programmes based on the comparable fitness cost, radiosensitivity and arbovirus susceptibility to its conspecifics. Abstract BACKGROUND The sterile insect technique (SIT) is a green and species‐specific insect pest control technique that suppresses target ...

Abstract Recovery, recolonization, and adaptation in a chemical stress context are processes that regenerate local populations and communities as well as the functions these communities perform. Recolonization, either by species previously present or by new species able to occupy the niches left empty, refers to a metacommunity process with stressed ...

Hyperovals in Knuth’s binary semifield planes
In each of the three projective planes coordinatised by the Knuth's binary semifield $\mathbb{K}_n$ of order $2^n$ and two of its Knuth derivatives, we exhibit a new family of infinitely many translation hyperovals. In particular, when $n=5$, we also present complete lists of all translation hyperovals in them. The properties of some designs associated

8 semifield planes of order 82
The authors work out a list of all eight translation planes of order 64 which contain GF(8) in its kernel and have a collineation group of order 128. By a result of \textit{M. Biliatti}, \textit{V. Jha}, the second author and \textit{G. Menichetti} [Geom. Dedicata 29, No.1, 7-43 (1989; Zbl 0673.51003)] they are all semifield planes.

On automorphisms of semifields and semifield planes
Изучается взаимосвязь полуполевой проективной плоскости и ее координатизирующего полуполя с использованием линейного пространства и регулярного множества. Установлен геометрический смысл инволюторного автоморфизма конечного полуполя, доказаны некоторые его свойства.

On translation hyperovals in semifield planes
In this paper we demonstrate the first example of a finite translation plane which does not contain a translation hyperoval, disproving a conjecture of Cherowitzo. The counterexample is a semifield plane, specifically a Generalised Twisted Field plane, of order $64$. We also relate this non-existence to the covering radius of two associated rank-metric

The avian gut microbiota constitutes a complex, multiphyla ecosystem that critically shapes host physiology, immune function, disease resistance, and antimicrobial resistance dynamics. Bacteria, archaea, fungi, and viruses collectively regulate nutrient metabolism, mucosal barrier integrity, and immunological maturation, whereas dysbiosis increases ...
