Cicada's wings as determinant factor for the sound emission: The case of \textit{Quesada gigas} [PDF]
Cicadas (Homoptera:Cicadidae) are insects able to produce loudly songs and it is known that the mechanism to produce sound of tymballing cicadas works as a Helmholtz resonator. In this work we offer evidence on the participation of the wings in a high quality resonating process which defines the details of the acoustic properties of the calling song ...

Modelling agricultural landscape complementation for natural pest control
Our modelling study provides insights in the role of landscape complementation for natural pest control in arable crops by revealing where resource discontinuities can become bottlenecks. Effective natural pest control relies on a variety of different habitats that provide floral and prey resources during different times of the year, for example a ...

Arthropod diversity in peas with normal or reduced waxy bloom [PDF]
Crop traits can alter economically important interactions between plants, pests, and biological control agents. For example, a reduced waxy bloom on the surface of pea plants alters interactions between pea aphids and their natural enemies. In this study,

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Costa Rica
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Costa Rica.
