التنوع الحيوي و ديناميكية المجتمع الحشري للخنافس الجوالة (Coleoptera : Carabidae)‎ في بعض بساتين الفاكهة في طرطوس، سورية

الملخص EN

The diversity and seasonal abundance of ground beetles were measured in a loquat and guava orchards located at the coastal area in Tartous, Syria from March to the end of September 2014.

The predatory beetles were captured by pitfalls traps.

Beetle species diversity was assessed using two indicators: species richness and Shannon index for both habitats.

Results indicated that beetles were found in both orchards in spring and early summer and disappeared in the fall.

One population peak was observed in loquat orchard with total catch of 46 individuals during May and two peaks in guava orchard in early May and early June with the same number of 22 individuals.

The overall abundance of carabids was reduced in both orchards in the late summer.

A total of 281 carabid beetles were collected and the species were identified as: Carabus hemprichi, Harpalus sp.

1, Harplaus sp.

2, Calathus sp.

and Pseudoophonus rufipes.

The dominant species was C.

hemprichi in loquat orchard, while Harpalus sp.

1 was the predominat species in guava orchard.

The dominant species should be investigated further to determine their role in regulating the pest population in fruit orchards in the agro-ecosystem of the Syrian coast.
