Survey of arthropod biodiversity in the brinjal field.

摘要

Field experiment was conducted to study the arthropod biodiversity in the brinjal field during February to August. Twenty species of harmful arthropods under 17 families were observed belonging to 6 different orders. The brinjal shoot and fruit borer (Leucinodes orbonalis), jassid (Amrasca biguttula biguttula), epilachna beetle (Epilachna sp.) white fly (Bemisia tabaci) and aphid (Aphis gossypii) were found as the most common and major insect pests of brinjal. Ten plant dwelling predaceous arthropod families were found in the field among them 42.44% were occupied by three families under Coleopteran insect. Spider under lycosidae family possessed 30.23%, which was ranked as the second most important arthropods. Surface dwelling arthropods caught in pitfall traps were grouped into 17 families among them 7 families were identified as predators. Formicidae was occupied 67% of the total surface dwelling predaceous arthropod.
