Baculoviruses manipulate host lipid metabolism via adipokinetic hormone signaling to induce climbing behavior.
Article in PLoS pathogens, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Baculoviruses can induce climbing behavior in caterpillar hosts, which provides an excellent model for studying parasite manipulation of host behavior. Herein, we found that Helicoverpa armigera single nucleopolyhedrovirus (HearNPV) promoted lipid metabolism of infected H. armigera larvae, and changes in lipid metabolism can affect climbing behavior. Therefore, understanding the molecular mechanisms between lipid metabolism and climbing behavior is particularly important. In this study, we found adipokinetic hormone 1 (HaAKH1), adipokinetic hormone 2 (HaAKH2) and their receptor HaAKHR were essential for promoting lipid metabolism and climbing behavior in response to HearNPV infection. Both molecular docking result and Ca2+ imaging showed that both HaAKH1 and HaAKH2 could interact with HaAKHR. Knockdown of HaAKH1, HaAKH2 and HaAKHR resulted in not only the accumulation of triacylglycerol (TAG), but also the reduction of the replication of HearNPV and the crawling ability of infected H. armigera larvae, resulting in a decrease in the final death height of the infected larvae. We further validated this conclusion by injecting active peptides of HaAKH1 and HaAKH2 to infected larvae. In addition, we investigated the downstream of HaAKH signaling and found that hormone-sensitive lipase (HaHSL) changed with changes in HaAKH signaling and HaHSL played the same role as HaAKH signaling. These findings not only revealed the mechanism by which parasites manipulated host lipid metabolism, but more significantly, explored the relationship between lipid metabolism and behavioral changes of hosts manipulated by parasites, broadening our understanding of the phenomenon of parasites manipulating host behavioral changes.
