Diapause completion in the almond seed wasp, Eurytoma amygdali (Hymenoptera: Eurytomidae) following early low temperature treatment

Role of Photoperiod and Temperature in Diapause Induction of Endoparasitoid Wasp Microplitis mediator (Hymenoptera: Braconidae)

Diapause in Microplitis mediator Haliday (Hymenoptera: Braconidae) is manifested during the pupal stage and normally occurs during the winter season because of a photoperiodic response that is highly dependent on temperature. No diapause was observed at temperatures above 20 Cregardless of the photoperiod.Only a small part of the population entered diapause at 20 Cunder short daylengths of ligh...

Karyotypic diversity in the subfamily Eurytominae (Hymenoptera: Eurytomidae).

New data on the karyotype structure of five species of the subfamily Eurytominae are described, including the following species: Eurytoma rosae (2n = 20), E. robusta (n =7, 2n = 14), E. serratulae (n = 6, 2n = 12), E. compressa (2n = 10) and Sycophila biguttata (2n = 18). 2n = 10, 12 and 14 are reported for the first time for the Eurytominae, in which only 2n = 20 and 18 have been previously fo...

Monitoring the Attack Incidences and Damage Caused by the Almond Bark Beetle, Scolytus amygdali, in Almond Orchards

The almond bark beetle, Scolytus amygdali Geurin-Meneville, is responsible for significant loss of fruit production in almond orchards throughout the world. Here, we studied the damage and the incidences of S. amygdali attack on two different scales: (1) at the level of a single tree; and (2) in an entire orchard. Our results revealed no differences in attack level among four orientations (east...
