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.

Selective and persistent toxicity of seven insecticides to five egg parasitoids of Spodoptera frugiperda

open access: yesCABI Agriculture and Bioscience
Background Spodoptera frugiperda, a major migratory and invasive pest, inflicts significant yield loss on rice and maize in China. As part of an integrated pest management system, biological control agents can be used against S.

Egg parasitoid attraction toward induced plant volatiles is disrupted by a non-host herbivore attacking above or belowground plant organs.

open access: yesFrontiers in Plant Science, 2014
Plants respond to insect oviposition by emission of oviposition-induced plant volatiles (OIPVs) which can recruit egg parasitoids of the attacking herbivore.

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.

Egg Parasitoids of Stink Bugs (Hemiptera: Coreidae and Pentatomidae) on Soybean and Cowpea in Brazil

open access: yes, 2015
Parasitoids naturally attacking stink bug (Hemiptera: Coreidae and Pentatomidae) eggs and interactions with their hosts were recorded on soybean (Glycine max [L.] Merril; Fabales: Fabaceae) and cowpea (Vigna unguiculata [L.] Walp.; Fabales: Fabaceae ...

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 ...

The Prevalence of Egg Parasitoids of Two Cobweb Spiders in a Tropical Urban Gradient

open access: yesArthropoda
Parasitoidism strongly influences the structure of the spiders’ populations, and it can be affected by environmental factors such as those caused by anthropogenic actions.

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 ...
