Summary

This summary is machine-generated.

The parasitoid wasp Telenomus dilophonotae was found in Paraná, Brazil, parasitizing Erinnyis ello eggs in cassava fields. This southernmost record provides new distribution data and DNA barcode for this important insect species.

Area Of Science

  • Entomology
  • Biological Pest Control
  • Biodiversity Studies

Background

  • Telenomus dilophonotae Cameron, 1913 (Hymenoptera, Scelionidae) has limited documented occurrences in South America.
  • Previous Brazilian records of T. dilophonotae were from Bahia, associated with rubber and cassava crops, parasitizing Erinnyis ello (Lepidoptera, Sphingidae).

Purpose Of The Study

  • To report the first occurrence of Telenomus dilophonotae in the state of Paraná, Brazil.
  • To document the southernmost distribution record for T. dilophonotae.
  • To provide genetic and morphological data for this parasitoid wasp.

Main Methods

  • Field surveys in cassava production areas in western Paraná.
  • Identification of parasitoid wasps and their hosts.
  • DNA barcoding for species identification and genetic analysis.
  • Geographic mapping of occurrence records.

Main Results

  • Telenomus dilophonotae was recorded for the first time in Paraná, Brazil.
  • The species was found parasitizing Erinnyis ello eggs in cassava fields (Manihot esculenta).
  • This represents the southernmost distribution record for T. dilophonotae, expanding its known range.
  • The first DNA barcode sequence for this species was generated, along with photographs and a distribution map.

Conclusions

  • The discovery in Paraná highlights the importance of continued biodiversity surveys in agricultural landscapes.
  • T. dilophonotae plays a role in the natural regulation of Erinnyis ello populations in Brazilian cassava agroecosystems.
  • The genetic data contributes to the taxonomic understanding and conservation of this beneficial insect.
