Whole‐genomic DNA amplifications from individually isolated sweet sorghum microspores

Applications in Plant Sciences, Volume 10, Issue 6, November-December 2022., 2022
Abstract Premise Sorghum is a multi‐use crop, the efficient breeding of which requires the development of new genetic tools. One such tool could be the genetic assessment of free microspores, which are released just after the tetrad stage of pollen development.

Archetype models upscale understanding of natural pest control response to land‐use change

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Control of crop pests by shifting host plant availability and natural enemy activity at landscape scales has great potential to enhance the sustainability of agriculture. However, mainstreaming natural pest control requires improved understanding of how its benefits can be realized across a variety of agroecological contexts. Empirical studies

Effects of cis-Jasmone Treatment of Brassicas on Interactions With Myzus persicae Aphids and Their Parasitoid Diaeretiella rapae

Frontiers in Plant Science, 2021
There is a need to develop new ways of protecting plants against aphid attack. Here, we investigated the effect of a plant defence activator, cis-jasmone (CJ), in a range of cultivars of Brassica napus, Brassica rapa and Brassica oleracea.

Assessing flower‐visiting arthropod diversity in apple orchards through metabarcoding of environmental DNA from flowers and visual census

Environmental DNA, Volume 5, Issue 1, Page 117-131, January 2023., 2023
The diversity of flower‐visiting arthropods in four Danish apple orchards was assessed using molecular (metabarcoding) and non‐molecular techniques. The aim was to obtain a broader overview of arhtropod communities present to support future management practices towards more sustainable agricultural systems.

Aquatic‐Terrestrial Insecticide Fluxes: Midges as Neonicotinoid Vectors

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 60-70, January 2023., 2023
Abstract Exposure of freshwater ecosystems to insecticides can negatively impact the development of emerging aquatic insects. These insects serve as an important nutritional subsidy for terrestrial insectivores. Changes in insect emergence phenology (i.e., emergence success and temporal pattern) or fluxes of insecticides retained by the emerging adults

Limited sex differences in plastic responses suggest evolutionary conservatism of thermal reaction norms: A meta‐analysis in insects

Evolution Letters, Volume 6, Issue 6, Page 394-411, December 2022., 2022
Abstract Temperature has a profound effect on the growth and development of ectothermic animals. However, the extent to which ecologically driven selection pressures can adjust thermal plastic responses in growth schedules is not well understood. Comparing temperature‐induced plastic responses between sexes provides a promising but underexploited ...

Breeding and selection of taro (Colocasia esculenta) for improved disease‐resistance in Hawaiʻi

PLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 123-145, January 2023., 2023
Taro is a root crop with wide geographic range and high cultural significance to Indigenous peoples of Hawaiʻi and the Pacific. Taro Leaf Blight (TLB) is a worldwide disease of taro, and Hawaiian taro varieties exhibited little resistance to it. To improve TLB‐resistance, conventional breeding was conducted by hand‐pollination.

First report of the aphid Tinocallis kahawaluokalani (Hem.: Aphididae) from Iran [PDF]

نامه انجمن حشره‌شناسی ایران, 2017
The aphid Tinocallis kahawaluokalani is reported here for the first time from Iran. The aphid specimens were collected on Crape myrtle bushes, Lagerstroemia spp. (Lythraceae), in the west of Mazandaran province in 2017.
