Table 1 Classification of included articles by micro-environmental factors covered

From: Impact of micro-environmental factors on survival, reproduction and distribution of Oncomelania hupensis snails

Micro-environmental factors (n, %) Detailed factor Effect Description
Water environment (32a, 24.1%)  
 Water level (25, 18.8%) Curve relationship An optimal range exists
 Water quality (7, 5.3%) Transparency (1) Positive effects Oncomelania hupensis were more likely to survive in water with high transparency
Chemical properties (6) Need further research Results from literatures conflict
Soil environment (37a, 27.8%)
 Soil properties (31, 23.3%) Soil humidity, temperature (18) Curve relationship An optimal range exists
Soil pH value (7) Curve relationship An optimal range exists
Soil fertility indexes (8b) organic compounds, total N, total P, total K, etc Need further research Results from literatures conflict
 Soil microorganisms (6, 4.5%) Aspergillus fumigatus SL-30, Streptomyces violaceoruber, Xanthobacter autotrophicus, etc Negative effects These microorganisms have molluscicidal activity
Vegetation (72a, 54.1%)
 Plant extracts (34, 25.6%) Root, stem, and leaf extracts Negative effects These plant extracts have molluscicidal activity
 Land cover vegetation characteristics (23, 17.3%) Vegetation height, coverage (12) Curve relationship An optimal range exists
Plant species (11)
Cynodon dactylon, Alternanthera philoxeroides, Pterocarya stenoptera community and Nerium indicum community, Liquidambar formosana, Sapium sebiferum, etc
Negative effects O. hupensis are less distributed in areas with these vegetation types
 Snail control and schistosomiasis prevention forest (14, 10.5%) Negative effects The implementation of snail control and schistosomiasis prevention forest reduces the density of O. hupensis
 Plant microorganisms (1, 0.8%) Endophyte JJ18 of Pseudolarix amabilis Negative effects These microorganisms have molluscicidal activity
Predator (4a, 3.0%)
 Procambarus clarkia, Ophiocephalus argus (4, 3.0%)   Negative effects Predation reduces the density of O. hupensis
  1. In the second column, the numbers in brackets represent the number of articles on related factors
  2. aSome of the articles discussed more than one influencing factors
  3. bTwo articles specified the subspecies O. hupensis quadrasi and showed that organic compounds had a positive impact on the snail survival
