Temporal fluctuations and geographic distributions of Leptopilina (Hymenoptera: Figitidae) species in North Carolina: implications for biological control of Drosophila suzukii (Diptera: Drosophilidae).
Article in Journal of economic entomology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Biological control is an important component of integrated pest management programs. This can include classical biological control agents, but also adventive biological control agents that naturally established. Here, we provide details of the presence and seasonal biology of potential biological control agents for the invasive Drosophila suzukii Matsumura in Southeastern USA blackberry production systems, including a recently established adventive parasitoid wasp species, Leptopilina japonica Novković & Kimura. To better understand the populations of this new species, we compare detection methods and report on temporal fluctuations and geographic distributions in North Carolina blackberry fields. In total, we collected 1,142 specimens from 6 sites including 5 different Leptopilina species: Leptopilina boulardi Barbotin, Carton & Kelner-Pillault, Leptopilina clavipes Hartig, Leptopilina heterotoma Thomson, Leptopilina japonica, and Leptopilina leipsi Lue & Buffington. We confirm previous reports of L. japonica, L. boulardi, and L. heterotoma in North Carolina, but report L. clavipes and L. leipsi in the state for the first time. While several Leptopilina species have now been documented in North Carolina, L. japonica shows the most promise as a biological control agent for D. suzukii. Understanding the when and where each of these parasitoid species is present in crop fields is an important first step in improving D. suzukii management efforts. These data will aid in understanding how best to protect these species and how best to incorporate them into on-farm management plans.
