Bottom–up and top–down diversification: asymmetric processes over space and time
Coevolution in trophic interactions is often considered as a major factor underlying diversification in interacting species. Most focus hitherto has however been on bottom–up processes where host‐associated differentiation drives diversification, and less on top–down processes through enemy‐associated differentiation.

Chalcosicya maya n. sp, a new Mexican species (Coleoptera: Chrysomelidae: Eumoplinae) and its implications for morphology and biogeography [PDF]
Chalcosicya maya, new species, (Coleoptera: Chrysomelidae: Eumolpinae) is described and the species key of Blake (1951) is modified to accommodate it. This is the first known mainland species of this previously Antillean genus.

Wasp communities associated with fig trees, Ficus spp., are a model system to investigate how local and regional processes shape biodiversity across large geographical ranges. We investigated the β‐diversity of fig wasp assemblages associated with three widely distributed Neotropical fig species – F. citrifolia, F. obtusifolia and F. pertusa – using 27

Wood wasp inspired space and earth drill [PDF]
In this chapter, we explain why the low gravity encountered on Mars or on the Moon and the low mass of the probes, landers and rovers that carry drilling devices limit classical drilling techniques.

Saltbush-associated Asphondylia species (Diptera: Cecidomyiidae) in the Mediterranean Basin and their chalcidoid parasitoids (Hymenoptera: Chalcidoidea) [PDF]
Numerous species of gall midges (Diptera: Cecidomyiidae) have been recorded from saltbush (Chenopodiaceae: Atriplex) around the world but only 11 of them belong to the large cecidomyiid genus Asphondylia. Of these, two species were de-scribed in the late

Fall armyworm (FAW) preferred ovipositing on vegetative‐stage soybeans. While ‘mother knows best’ may not apply in soybean‐FAW system, muffled cues in the reproductive stage could positively influence host success. Abstract BACKGROUND While the mother knows best/preference performance hypothesis has been well tested in natural ecosystems, how these ...

The oviposition behaviour of Gryon gallardoi (Brèthes, 1914) on eggs of Spartocera dentiventris Mendonça Jr. (Berg, 1884) of different ages (2, 3, 4, 5, 6, 7, 8 and 12 days) was investigated.

Highlights: The contribution of winter and early spring‐available fruit (Aucuba japonica, Elaeagnus ×submacrophylla, and Viscum album) to the performance of D. suzukii depended on their P:C ratio and biophysical properties Even though D. suzukii performance was the lowest in A.

Aphidiinae (Hymenoptera, Braconidae) aphid parasitoids of Malta : review and key to species [PDF]
This paper brings an annotated list of the 16 aphid parasitoids detected up to 2015 in Malta. All the species were reared from identified aphid-plant associations. An illustrated key to the identification of the recorded species from Malta is provided.
