Intrinsic competition and its effects on the survival and development of three species of endoparasitoid wasps

, 2009
In natural systems, pre-adult stages of some insect herbivores are known to be attacked by several species of parasitoids. Under certain conditions, hosts may be simultaneously parasitized by more than one parasitoid species (= multiparasitism), even ...

Noncrop flowering plants restore top-down herbivore control in agricultural fields [PDF]

, 2013
Herbivore populations are regulated by bottom-up control through food availability and quality and by top-down control through natural enemies. Intensive agricultural monocultures provide abundant food to specialized herbivores and at the same time ...

Antennal Structures Used in Communication by Egg Parasitoids [PDF]

, 2009
Egg parasitoids are considered the most effective biocontrol agents of crop pests among parasitic wasps, since they are able to remove the herbivore from the agroecosystem before larval eclosion. The use of arthropod eggs as hosts by parasitoids has evolved in the Hymenoptera at least in 14 families.

Field Control Effect of Telenomus remus Nixon and Trichogramma chilonis Ishii Compound Parasitoid Balls against Spodoptera frugiperda (J. E. Smith)

Insects
Although the release of egg parasitoids has proven to be an effective strategy for the control of the fall armyworm (FAW), a single egg parasitoid, however, has exposed some deficiencies in practice, and it is worthwhile to explore whether the ...

Egg parasitoid attraction toward induced plant volatiles is disrupted by a non-host herbivore attacking above or belowground plant organs.

Frontiers in Plant Science, 2014
Plants respond to insect oviposition by emission of oviposition-induced plant volatiles (OIPVs) which can recruit egg parasitoids of the attacking herbivore.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Impacts of belowground herbivory on oviposition decisions in two congeneric butterfly species

, 2010
Root-feeding insects can affect the performance of aboveground insect herbivores when they are forced to feed on the same host plant. Here we explored whether the oviposition behaviour of two closely related herbivorous species (cabbage butterflies ...

First record of Gonatocerus litoralis (Haliday) (Hymenoptera: Mymaridae) from Anoplotettix putoni Ribaut (Hemiptera: Cicadellidae)

Journal of Entomological and Acarological Research, 2013
The mymarid Gonatocerus litoralis (Haliday) is recorded for the first time as an egg parasitoid of the leafhopper Anoplotettix putoni Ribaut. A study of the main morphological characters shows unusual variation in distribution of the multiporous plate ...

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

Pest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Functional response and life history parameters of Apanteles taragamae, a larval parasitoid of Maruca vitrata

, 2010
The legume pod borer Maruca vitrata Fabricius (Lepidoptera: Crambidae) is a serious pest of cowpea in West-Africa. The parasitoid Apanteles taragamae Viereck (Hymenoptera: Braconidae) that originates from Taiwan is a potential candidate for biological ...
