Testing optimal defense theory: Root resistance selection in chicory (Cichorium intybus) reduces foliar defense and alters aphid performance and feeding behavior

open access: yesPest Management Science, EarlyView.
Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...

The epidemiology of the blackleg pathogen, Leptosphaeria maculans, impacts fungicide resistance management strategies

open access: yesPest Management Science, EarlyView.
Understanding how infection timing drives disease is essential for the development of fungicide resistance management strategies. For blackleg disease of canola, all infection timings can contribute to the following generation, therefore all fungicide applications have the ability to select for resistance.

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

open access: yesPest Management Science, EarlyView.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Evaluating astigmatid mites as supplemental food for Macrolophus pygmaeus: contrasting responses between commercial and wild populations

open access: yesPest Management Science, EarlyView.
Astigmatid mites provide low‐cost supplemental food for Macrolophus pygmaeus, supporting survival and development, with population‐specific responses and Acarus siro and Carpoglyphus lactis as the most promising alternatives. Abstract BACKGROUND Early establishment of Macrolophus pygmaeus in crops depends on the availability of supplemental food ...

Effects of pupal hypoxia duration and holding temperature on quality control parameters of sterile Queensland fruit fly

open access: yesPest Management Science, EarlyView.
Queensland fruit fly pupae tolerate hypoxia up to 2 days without compromising quality. Prolonged hypoxia, especially at 25 °C, reduces emergence and flight ability. Storage at 18 °C is recommended. Abstract BACKGROUND The sterile insect technique is used to eradicate outbreaks of Queensland fruit fly (Q‐fly) Bactrocera tryoni (Froggatt) in fruit‐fly ...
