Experimental evolution of immunological specificity
Innate immune memory (i.e., immune priming) is found in many invertebrates. In some cases, immune priming provides protection against infection only when the same bacteria are used for priming and challenge; that is, priming can be specific.

In low‐latitude mountains, we found insectivorous bird communities switched from breeding before to after the dry season at a threshold in dry‐season insects. Localized breeding season reversal of insectivores across wet‐to‐dry gradients magnified short‐term effects of drought and contrasted with the seasonal stability of nectar‐fruit consumers.

Los Nemátodos Entomopatógenos: una alternativa en la lucha contra el gusano cabezudo (Capnodis Tenebrionis Linnaeus) (Coleoptera, Buprestidae) [PDF]
El gusano cabezudo Capnodis tenebrionis es una importante plaga de los cultivos de frutales de hueso. La larva de este coleóptero se desarrolla y alimenta en el interior de las raíces de los árboles atacados, lo que dificulta su lucha con los ...

Enhancement of Bacillus thuringiensis toxicity by feeding Spodoptera littoralis larvae with bacteria expressing immune suppressive dsRNA [PDF]
RNAi interference (RNAi) for insect pest control is often used to silence genes controlling vital functions, thus generating lethal phenotypes. Here, we propose a novel approach, based on the knockout of an immune gene by dsRNA-expressing bacteria as a ...

Analysis of plasmid transconjugants relative to plasmid‐free and plasmid‐carrying Serratia spp. demonstrates erratic disease phenotypes and reduced fitness. Transconjugants also show reduced ability to degrade substrates associated with virulence, supported by transcriptomic data.

From beginning to end: the synecology of tree‐killing bark beetles, fungi, and trees
ABSTRACT Over a century of research has revealed an amazing complexity of behaviours and physiological adaptations that allow tiny bark beetles to overcome large trees, sometimes resulting in outbreaks that kill millions of trees. Turning a tree into a home and successfully raising offspring involves constant interactions among the beetles, the tree ...

Pareto-efficient biological pest control enable high efficacy at small costs [PDF]
Biological pest control is increasingly used in agriculture as a an alternative to traditional chemical pest control. In many cases, this involves a one-off or periodic release of entomopathogens.
