Pareto-efficient biological pest control enable high efficacy at small costs [PDF]

open access: yesarXiv, 2016
Biological pest control is increasingly used in agriculture as a an alternative to traditional chemical pest control. In many cases, this involves a one-off or periodic release of naturally occurring and/or genetically modified enemies such as predators, parasitoids, or pathogens. As the interaction between these enemies and the pest is complex and the

High-throughput profiling of diapause regulated genes from Trichogramma dendrolimi (Hymenoptera: Trichogrammatidae)

open access: yesBMC Genomics, 2020
Background The parasitoid wasp, Trichogramma dendrolimi, can enter diapause at the prepupal stage. Thus, diapause is an efficient preservation method during the mass production of T. dendrolimi.

Stability Analysis and Control Optimization of a Prey-Predator Model with Linear Feedback Control

open access: yesDiscrete Dynamics in Nature and Society, 2018
The application of pest management involves two thresholds when the chemical control and biological control are adopted, respectively. Our purpose is to provide an appropriate balance between the chemical control and biological control.

A Constant Introduction of Additional Food Does Not Yield Pest Eradication in Finite Time [PDF]

open access: yesarXiv, 2018
Biological control, the use of predators and pathogens to control target pests, is a promising alternative to chemical control. It is hypothesized that the introduced predators efficacy can be boosted by providing them with an additional food source.

Biological Control of Insect Pests in Bermuda

open access: yesBulletin of Entomological Research, 1959
Projects undertaken on the biological control of insect pests in Bermuda since the first introduction of Bufo marinus in 1875 and including those still in progress are discussed. Work on 15 pests or groups of pests has been undertaken involving the introduction of over one hundred species of beneficial organisms.Icerya purchasi Mask.
