Systematic Continental Scale Monitoring by Weather Surveillance Radar Shows Fewer Insects Above Warming Landscapes in the United States. [PDF]

open access: yesGlob Chang Biol
Systematic remote sensed monitoring of insect density in the air shows fewer insects above warming landscapes in the United States. We estimate insect density at continental scales for the first time by leveraging the nationwide network of weather radars.

Evaluation of Experimental Populations and Glandular-Haired Varieties of Alfalfa for Alfalfa Blotch Leafminer (Diptera: Agromyzidae) Feeding Injury [PDF]

open access: yes, 2018
Following the spread of the alfalfa blotch leafminer, Agromyza frontella (Rondani) (Diptera: Agromyzidae), into Minnesota and Wisconsin U.S.A. during 1994-1997, three field trials were conducted in Minnesota to assess the potential for leafminer ...

Selective leaf surface defenses: trichomes trap herbivorous leafminers but spare parasitoid wasps. [PDF]

open access: yesPest Manag Sci
Hooked trichomes on kidney bean leaves selectively entrap leafminer flies but rarely affect parasitoid wasps. This morphological barrier enables pest suppression with minimal impact on beneficial insects, offering insights for breeding pest‐resistant cultivars compatible with biological control. Abstract BACKGROUND Leafminers [e.g., Liriomyza trifolii (

The Distribution and Prevalence of the Alfalfa Blotch Leafminer (Diptera: Agromyzidae) in Illinois [PDF]

open access: yes, 2018
Surveys were made in 2001 and 2002 to determine the distribution and prevalence of the alfalfa blotch leafminer, Agromyza frontella (Diptera: Agromyzidae), and its primary parasitoids, Dacnusa dryas and Chrysocharis liriomyzae (Hymenoptera: Braconidae ...

Biological Control of Alfalfa Blotch Leafminer (Diptera: Agromyzidae) in Ontario: Status and Ecology of Parasitoids (Hymenoptera: Braconidae, Eulophidae) 20 Years After Introduction [PDF]

open access: yes, 2018
Two European parasitoid species were released in Ontario during the late 1970\u27s to control the alfalfa blotch leafminer, Agromyza frontella (Rondani) (Diptera: Agromyzidae). One of these, Dacnusa dryas (Nixon) (Hymenoptera: Braconidae), rapidly became
