Effects of Lemon Orchards Types with Different of the Land Use Types in Early Stage on Hemipteran Insects: a Case Study in Lancang County, Yunnan Province

PurposeIn order to explore the effects of the land use types in early stage on Hemipteran insect communities in lemon orchards.

MethodThe Hemipteran insect communities were investigated by sweep netting and pitfall traps in three types of lemon orchards in Lancang County, Yunnan Province in April and July, 2016.

Result(1) Species and composition and relative abundance: 1 163 Hemipteran insect individuals were collected in the natural forest transformation lemon orchards, representing 55 species; 3 136 Hemipteran insect individuals were collected in the farmland transformation lemon orchards, representing 49 species; 4 285 Hemipteran insect individuals were collected in the wasteland transformation lemon orchards, representing 34 species. (2) Diversity comparisons: there were significant differences of Hemipteran insects abundance and pest abundance, Hemipteran insects and pest abundance ranked as wasteland transformation lemon orchards>farmland transformation lemon orchards>natural forest transformation lemon orchards; there were significant differences of Hemipteran insects species richness and pest species richness, Hemipteran insects and pest species richness ranked as natural forest transformation lemon orchards>farmland transformation lemon orchards>wasteland transformation lemon orchards; there were significant differences of beneficial insect abundance, wasteland transformation lemon orchards had the highest beneficial insect abundance; there were no significant differences of beneficial insect species richness. (3) Community structures: three types of lemon garden Hemipteran insect community structure was not similar. (4) Correlation analysis: species richness of Hemipteran insects were significantly correlated with herb abundance and herb abundance, species richness of Hemipteran insect decreased with increasing of herb species richness, and first increased then tend to be stable with increasing of herb species abundance.

ConclusionDiversity of Hemipteran insect communities in lemon orchards was affected by the land use types in early stage.
