Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

open access: yesPest Management Science, EarlyView.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the

Theoretical Study of Pest Control Using Stage Structured Natural Enemies with Maturation Delay: A Crop-Pest-Natural Enemy Model [PDF]

open access: yes, 2013
In the natural world, there are many insect species whose individual members have a life history that takes them through two stages, immature and mature. Moreover, the rates of survival, development, and reproduction almost always depend on age, size, or

Leaf penetration by endophytic Metarhizium brunneum enables infection of Phthorimaea absoluta in tomato mines while inducing the crop defense system

open access: yesPest Management Science, EarlyView.
Spraying Metarhizium brunneum on tomato plants controls heterogeneous and upcoming Phthorimaea absoluta populations by infecting larvae within mines and priming plant induced systemic defences. Abstract BACKGROUND The endophytic entomopathogenic fungus Metarhizium brunneum Petch EAMa 01/58‐Su shows strong potential for managing Phthorimaea absoluta, a ...

Organic Centre Wales Technical Note 5: Biology and management of wireworms [PDF]

open access: yes, 2005
Wireworms are the larvae of a group of beetles commonly known as click beetles. After falling on their backs they right themselves by flicking themselves into the air and produce a “clicking” sound.

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

open access: yesPest Management Science, EarlyView.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.

Ecological Balance in Unmanaged Beech Reserves: Scolytids or Their Natural Saproxylic Beetle Enemies?

open access: yesInsects
The accumulation of dead wood can serve as a potential source of insect pests, with scolytids being the most frequently discussed group. The aim of this study was to quantify the abundance and species composition of scolytids and their natural saproxylic

Functional biodiversity to improve pest control in organic cropping systems [PDF]

open access: yes, 2013
A sustainable use of functional agrobiodiversity (FAB) providing habitats with suitable floral resources is needed to conserve and improve pest control by natural enemies in organic cropping and other low-input systems.

Evaluating astigmatid mites as supplemental food for Macrolophus pygmaeus: contrasting responses between commercial and wild populations

open access: yesPest Management Science, EarlyView.
Astigmatid mites provide low‐cost supplemental food for Macrolophus pygmaeus, supporting survival and development, with population‐specific responses and Acarus siro and Carpoglyphus lactis as the most promising alternatives. Abstract BACKGROUND Early establishment of Macrolophus pygmaeus in crops depends on the availability of supplemental food ...

Aphid control using natural enemies: Lessons for fine-tuning banana-aphid management

open access: yesBiological Control
Aphids are serious crop pests and vectors of plant-pathogenic viruses. Natural enemies (parasitoids, pathogens, and predators) can be effective aphid control agents. Vector control can achieve the sustainable management of vector-borne diseases. However,
