The rose sawfly, Arge ochropus (Gmelin), is one of the most destructive pests attacking rose bushes in northernIran. In the present study, the haemocyte reactions of A. ochropus larvaewere assessed against two entomopathogenicnematodes, Steinernema carpocapsae (Weiser) and Heterorhabditis bacteriophora Poinar. With injection ofinfective juveniles of H. bactriophora into A. ochropus larvae, the total haemocyte count showed alternatingfluctuations at all time intervals. Encapsulation occurred 22 hours post injection (hpi) of H. bacteriophorainfective juveniles into the rose sawfly larvae, while melanization was observed after 24 h. In the case of S. carpocapsae, initial attachment of the haemocytes was detected at 18 hpi and complete encapsulation at24 hpi; no melanization was observed. In general, findings showed strong immune responses of the rose sawflylarvae against H. bacteriophora,while these reactionswere weakened for S. carpocapsae. Therefore, it is concludedthat S. carpocapsae has more ability to overcome the host defence system, and this research provides a newwindow on its potential as a biocontrol agent.

Polylysine–resorcinol coated alumina nanotube has been synthesized based on Mannich reaction. Synthetic polymer has been obtained using lysine and resorcinol as monomer and p-formaldehyde aslinker by condensation reaction. The nanosorbent was employed for cadmium adsorption from aqueoussamples. Effective parameters on sorption process have been optimized with Box–Behnken design (BBD). Equilibrium time was 11 min as well as adsorption capacity was 220 mg g 1. Regeneration of the sorbentwas performed with HNO3 solution (0.5 mol L 1). The accuracy of the method was evaluated bydetermination of cadmium in various real samples.
