Beauveria Bassiana Triggers Soybean Systemic Resistance and Causes Sublethal Effects in Spodoptera frugiperda

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The interaction of soybean plant and the endophytic microorganism Beauveria bassiana was evaluated by inoculating a single trifoliate leaf. The effects of this inoculation on the herbivory, larval development, and life traits of Spodoptera frugiperda were measured.

A New Experimental Setup to Study the Olfactory Behaviour of Trichogramma Egg Parasitoids

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We developed an experimental setup to assess odor‐induced egg‐laying behavior in tiny egg‐parasitoid wasps. This Y‐shaped olfactometer, coupled with an AI‐based image‐recognition model, automatically quantifies egg parasitism by Trichogramma wasps. Olfactory‐driven egg‐laying preferences were analyzed using Bayesian inference.

The first record of Aphidius ervi Haliday in Slovenia

open access: yesActa Agriculturae Slovenica, 2009
In 2008, a lucerne aphid parasitoid Aphidius ervi Haliday was first recorded in Slovenia. This oligophagous parasitoid is used as biological control agent against bigger aphid species. By sampling aphid mummies on different locations in Slovenia in 2008,

Orchard Management Influences Predation of Halyomorpha halys Eggs

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We investigated predation of eggs of the invasive stink bug Halyomorpha halys on apple trees in conventional, organic, and extensively managed Dutch orchards. Predation exceeded 40% in extensively managed orchards but was only about 10% in conventional and organic ones. We used camera traps to reveal natural enemies that may contribute to H.

Solving the trophic puzzle: Host–parasite associations in Neotropical fig wasps associated with fig trees of section Americanae

open access: yesEcological Entomology, EarlyView.
We determined the trophic associations among fig wasp species associated with Ficus citrifolia by integrating gall morphology, the temporal sequence of wasp colonization, and oviposition behaviour. Dissection of galls produced by four gall‐inducing species at a late developmental phase enabled direct identification of occupants and inference of host ...

Parasitoid species diversity has no effect on protective symbiont diversity in experimental host‐parasitoid populations

open access: yesEcology and Evolution
How does diversity in nature come about? One factor contributing to this diversity are species interactions; diversity on one trophic level can shape diversity on lower or higher trophic levels.

Nutrient addition, but not vertebrate predator exclusion, shapes arthropod communities and herbivory in a temperate forest

open access: yesEcological Entomology, EarlyView.
We experimentally manipulated top‐down (predator exclusion) and bottom‐up (fertilisation) forces in a temperate forest understory to test effects on arthropod densities, body sizes and herbivory. Predator exclusion had no detectable effect on arthropod density, herbivory damage or body size, whereas fertilisation increased herbivory damage and ...

Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

open access: yesEcological Entomology, EarlyView.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...
