Bioefficacy of insecticides used against diamondbackmoth and their potential impact on natural enemies in cauliflower [PDF]

open access: yes, 2022
Field experiments were conducted at two different geographical regions viz., tropical region (Naraseepuram village, Coimbatore) and temperate region (Kookal village, Kotagiri, The Nilgiris) in summer and winter season’s to assess the bioefficacy of ...

Using plant chemistry to improve interactions between plants, herbivores and their natural enemies: challenges and opportunities [PDF]

open access: yes, 2021
Plant secondary (or specialized) metabolites determine multitrophic interaction dynamics. Herbivore natural enemies exploit plant volatiles for host location and are negatively affected by plant defense chemicals that are transferred through herbivores ...

The state of commercial augmentative biological control: plenty of natural enemies, but a frustrating lack of uptake [PDF]

open access: yes, 2012
Augmentative biological control concerns the periodical release of natural enemies. In com- mercial augmentative biological control, natural enemies are mass-reared in biofactories for release in large numbers to obtain an immediate control of pests. The

Natural enemies drive geographic variation in plant defenses [PDF]

open access: yes, 2012
Plants defend themselves against attack by natural enemies, and these defenses vary widely across populations. However, whether communities of natural enemies are a sufficiently potent force to maintain polymorphisms in defensive traits is largely ...

Hibernation of predatory arthropods in semi-natural habitats. [PDF]

open access: yes, 2009
Non-crop habitats provide important resources for natural enemies. Many natural enemies hibernate in non-crop habitats, from which they may colonise arable fields in the spring.

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.

The effect of within-crop habitat manipulations on the conservation biological control of aphids in field-grown lettuce [PDF]

open access: yes, 2011
Within-crop habitat manipulations have the potential to increase the biological control of pests in horticultural field crops. Wildflower strips have been shown to increase the abundance of natural enemies, but there is little evidence to date of an ...

Detection of refuge from enemies through phenological mismatching in multitrophic interactions requires season-wide estimation of host abundance [PDF]

open access: yes, 2011
The concept of ‘‘enemy-free space’’ (EFS) refers to ways of living that reduce or eliminate the vulnerability of a species to natural enemies. It has been invoked to explain host shifts of phytophagous insects.
