1 · What the graph read from it

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.

2 · The registry

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

The bio-efficacy of Solanum xanthocarpum leaf extract and bacterial insecticide, Bacillus thuringiensis, were assessed against the first to fourth instar larvae and pupae of Culex quinquefasciatus, under the laboratory conditions. The medicinal plants were collected from the outskirt Bharathiar University, Coimbatore, Tamil Nadu, India. The shade dried plant materials were extracted by employing the Soxhlet apparatus with ethanol (organic solvent) for 8 h and filtered. The extracts were concentrated at reduced temperature on a rotary evaporator and stored at a temperature of 4°C. Both S. xanthocarpum and B. thuringiensis show varied degree of larvicidal and pupicidal activity against various stages of C. quinquefasciatus. The LC(50) and LC(90) of S. xanthocarpum against the first to fourth instar larvae and pupae were 155.29, 198.32, 271.12, 377.44, and 448.41 ppm and 687.14, 913.10, 1,011.89, 1,058.85, and 1,141.65 ppm, respectively. On the other hand, the LC(50) values of B. thuringiensis against the first to fourth instar larvae and pupae were 133.88, 157.14, 179.44, 206.80, and 240.74 ppm; the LC(90) values were 321.04, 346.89, 388.86, 430.95, and 492.70 ppm, respectively. However, the combined treatment of S. xanthocarpum + B. thuringiensis (1:2) material shows highest larvicidal and pupicidal activity of the LC(50) values 126.81, 137.62, 169.14, 238.27, and 316.02 ppm and the LC(90) values 476.36, 613.49, 705.29, 887.85, and 1,041.73 ppm against C. quinquefasciatus in all the tested concentrations than the individuals and clearly established that there is a substantial amount of synergist act. Therefore, the present investigation clearly exhibit that both S. xanthocarpum and B. thuringiensis materials could serve as a potential of highest mortality rate against the mosquito larvae laboratory as well as the field conditions. Since C. quinquefasciatus is a ditch breeder vector mosquito, this is a user and eco-friendly biopesticide for the control of mosquito vector management program.
