Insecticidal effect of two plant extract seeds, on Agonoscena pistaciae (Hemiptera: Aphalaridae) under laboratory conditions

Mansore Hassanshahi, Mohammad Reza Hassani and Zahra Sheibani

The pistachio psyllid, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Aphalaridae), is a severe pest of pistachio trees in all pistachio planted area. The toxicity of seed extracts of two plants Amygdalus scoparia and Prunus dulcis var amara were tested against fifth instar nymphs of A. pistaciae under laboratory conditions. Bioassay was carried out using a dipping technique. The results showed that A. scoparia and P. dulcis var amara seed extracts were effective against A. pistaciae. Mortality of fifth instar nymphs were significantly increased with increasing concentrations of both plant extracts. Probit analysis of concentration-mortality data were conducted to estimate the LC50 value. The results showed that A. scoparia with LC50 value of 1494.00 ml/L was more toxic than P. dulcis var amara (1968.78 ml/L) on fifth instar nymphs of A. pistaciae. According to LC50 values, no significant differences were observed between A. scoparia and P. dulcis var amara 24 h post- treatment. Our results suggest that seed extracts of A. scoparia and P. dulcis var amara are suitable potentially compounds to control of A. pistaciae.
