Development, Survival and Phenology of the Sweetclover Weevil Parasitoid, \u3ci\u3ePygostolus Falcatus\u3c/i\u3e (Hymenoptera: Braconidae) [PDF]

, 2018
Biennial sweetclovers were widely used for soil improvement and as for- ages in the first half of the 1900s. The introduction of the sweetclover weevil, Sitona cylindricollis, caused a drastic decline in sweetclover acreage.

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.

Parasitoid wasp controls blue gum psyllid [PDF]

California Agriculture, 1998
The blue gum psyllid was first discovered in North America in Monterey County in January 1991. Since then it has quickly spread throughout the California coastal area and has became a major pest on Eucalyptus palverulenta in commercial foliage plantations. Large amounts of pesticides have been used to control the psyllid in these plantations. A primary

Host and symbiont genetic contributions to fitness in a Trichogramma-Wolbachia symbiosis. [PDF]

, 2018
The fitness effects associated with Wolbachia infection have wide-ranging ecological and evolutionary consequences for host species. How these effects are modulated by the relative influence of host and Wolbachia genomes has been described as a balancing

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.

Ooencyrtus pitosina (Hymenoptera: Encyrtidae)-A natural enemy of Samoan swallowtail butterfly Papilio godeffroyi (Lepidoptera: Papilionidae).

PLoS ONE, 2023
A new species of encyrtid wasp, Ooencyrtus pitosina Polaszek, Noyes & Fusu sp. n., (Hymenoptera: Encyrtidae: Encyrtinae) is described as a gregarious parasitoid in the eggs of the endemic Samoan swallowtail butterfly Papilio godeffroyi (Lepidoptera ...

Extrinsic Inter- and Intraspecific Competition in Parasitoid Wasps

Annual Review of Entomology, 2022
The diverse ecology of parasitoids is shaped by extrinsic competition, i.e., exploitative or interference competition among adult females and males for hosts and mates. Adult females use an array of morphological, chemical, and behavioral mechanisms to engage in competition that may be either intra- or interspecific.

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Phenological Attributes and Phylogenetic Relationships of \u3ci\u3eRhagoletis Juniperina\u3c/i\u3e Marcovitch (Diptera: Tephritidae) in the Great Lakes Region [PDF]

, 2018
Rhagoletis juniperina Marcovitch (Diptera: Tephritidae) infests Eastern Red Cedar (Juniperus virginiana L.) and other North American junipers. While several Rhagoletis species are of interest as orchard crop pests (apple maggot, blueberry maggot, cherry ...

Rhizobacteria regulate colonising Sitobion avenae aphid populations through induced host resistance and alter plant volatiles promoting early parasitoid recruitment on barley (Hordeum vulgare)

Pest Management Science, EarlyView.
Rhizobacterial inoculation of barley reduced Sitobion avenae populations by inducing plant resistance and modifying volatiles that attracted parasitoid wasps earlier, enhancing both bottom‐up and top‐down pest control. Abstract BACKGROUND Soil rhizobacteria can enhance crop resistance to insect herbivores and influence higher trophic interactions ...
