Effect of Photoperiod and Temperature on the Life Table Parameters of Onion Thrips (Thrips tabaci) Lineages

Journal of Horticultural Research, 2022
This study investigated the effect of photoperiod and temperature on the bionomics of the three Thrips tabaci lineages (L1 and L2 – leek-associated, and T – tobacco-associated).

Restricted Gene Flow among Lineages of Thrips tabaci Supports Genetic Divergence Among Cryptic Species Groups. [PDF]

PLoS ONE, 2016
Knowledge of the relative influence of population- versus species-level genetic variation is important to understand patterns of phenotypic variation and ecological relationships that exist among and within morphologically indistinguishable cryptic ...

The kin selection theory of genomic imprinting and modes of reproduction in the eusocial Hymenoptera

Biological Reviews, Volume 98, Issue 2, Page 677-695, April 2023., 2023
ABSTRACT Genomic imprinting is known from flowering plants and mammals but has not been confirmed for the Hymenoptera even though the eusocial Hymenoptera are prime candidates for this peculiar form of gene expression. Here, the kin selection theory of genomic imprinting is reviewed and applied to the eusocial Hymenoptera.

The Existence of Deuterotokous Reproduction Mode in the T. tabaci (Thysanoptera: Thripidae) Cryptic Species Complex

Journal of Horticultural Research, 2020
The present study aimed to investigate whether adult males could fertilize immature female pupae in the leek (L1) and tobacco-associated (T) Thrips tabaci lineages and to investigate the potential effects of mother to son inbreeding on the appearance of ...

Detection of Gene Flow from Sexual to Asexual Lineages in Thrips tabaci (Thysanoptera: Thripidae). [PDF]

PLoS ONE, 2015
Populations of Thrips tabaci are known to have two sympatric but genetically isolated reproductive modes, arrhenotoky (sexual reproduction) and thelytoky (asexual reproduction).

Identification of two leafminer parasitoids (Hymenoptera: Eulophidae), Neochrysocharis formosa and Proacrias sp. from Australia, with both showing thelytoky and infection by Rickettsia

Austral Entomology, Volume 61, Issue 3, Page 358-369, August 2022., 2022
Abstract Liriomyza huidobrensis, L. sativae and L. trifolii are polyphagous agromyzid leafminers that have recently arrived in Australia, posing a threat to Australian vegetable and ornamental crops. Adventive and endemic hymenopteran parasitoids of agromyzid leafminers already present in Australia should assist in the management of these invasive ...

Evolution of parasitoid host preference and performance in response to an invasive host acting as evolutionary trap

Ecology and Evolution, Volume 12, Issue 7, July 2022., 2022
Invasive species can act as an evolutionary trap for parasitoids when they are unsuitable for reproduction but indistinguishable from suitable hosts. Such incompatible interactions reduce parasitoids’ fitness and can reduce the viability of the population. Using an individual based model, we show how genetic variation in host preference and performance

Spontaneous parthenogenesis in the parasitoid wasp Cotesia typhae: low frequency anomaly or evolving process?

Peer Community Journal, 2022
Hymenopterans are haplodiploids and unlike most other Arthropods they do not possess sexual chromosomes. Sex determination typically happens via the ploidy of individuals: haploids become males and diploids become females.

Native egg parasitoids on Leptoglossus occidentalis Heidemann (Hemiptera: Coreidae) in Spain: Potential biological control agents?

Journal of Applied Entomology, Volume 146, Issue 5, Page 525-538, June 2022., 2022
Abstract Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae), commonly known as western conifer seed bug (WCSB), is an invasive pest in the Mediterranean, where it has been associated with the decline of Pinus pinea L. kernel production. A biological control of WCSB populations with native egg parasitoids may reduce economic losses.

Commodity risk assessment of Acer palmatum plants grafted on Acer davidii from China

EFSA Journal, Volume 20, Issue 5, May 2022., 2022
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by 2‐year‐old bare rooted plants for planting of ...
