EPPO Bulletin, Volume 54, Issue 3, Page 369-380, December 2024.Abstract Cereal grains both for human consumption and animal feed are an essential component of global food systems. However, during production they are often targeted by various pest insects, including aphids. A survey was carried out from 2017 to 2021 in six cereal production sites in Tunisia to evaluate aphid diversity and identify natural enemies ...

Bifurcation and Chaos in a Parasitoid-Host-Parasitoid Model
International Journal of Modern Nonlinear Theory and Application, 2018 This paper discusses a parasitoid-host-parasitoid ecological model and its dynamical behaviors. On the basis of the center manifold theorem and bi-furcation theory, the existence conditions of the flip bifurcation and Neimark-Sacker bifurcation are derived. In the end of the paper, some typical numerical experiments are performed, which illustrate that

Journal of Applied Ecology, Volume 61, Issue 2, Page 304-315, February 2024.To achieve lower pest burdens and higher abundances of potential pollinators and natural enemies, African cocoa farms should maintain a dense canopy of shade trees. The current shift towards high‐intensity cocoa farming in Africa could result in long‐term losses due to pest infestations and loss of arthropod‐mediated ecosystem services.

Frutíferas hospedeiras de moscas-das-frutas: arrancá-las ou conservá-las?
Agropecuária Catarinense, 2022 No Sul do Brasil, a incidência da mosca-das-frutas sul-americana Anastrepha fraterculus (Diptera: Tephritidae) tem sido uma das principais limitações à produção de frutíferas de clima temperado nativas e exóticas.

Moscas minadoras del girasol y sus enemigos naturales [PDF]
RIA: Revista Investigaciones Agropecuarias, 2011 Las "moscas minadoras" se caracterizan por excavar túneles ("minas") en el interior de las hojas, consumiendo el mesófilo y dejando intacta la epidermis foliar o, al menos, su pared externa.
