Optimal irradiation parameters for the development of the sterile insect technique in the seedcorn maggot Delia platura (Diptera: Anthomyiidae)

Pest Management Science, EarlyView.
X‐ray irradiation of Delia platura pupae showed that 20 Gy induces high sterility while maintaining male quality and competitiveness, establishing optimal parameters for sterile insect technique implementation in North America. Abstract BACKGROUND The seedcorn maggot, Delia platura Meigen (Diptera: Anthomyiidae), is a sporadic but economically ...

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

An AI‐based and coding‐free integration for forest Leaf Area Index calculation

Methods in Ecology and Evolution, EarlyView.
Abstract Seasonal and spatial variations in Leaf Area Index (LAI, or plant area index, PAI) are challenging to delineate in tropical forests because the changes are often too subtle to be reliably detected. Many existing DHP software tools offer one‐click processing of all images using auto‐threshold segmentation (e.g.
