Different Attractive Effects and EAG Responses of Ips subelongatus (Coleoptera, Scolytidae) and Its Predator Thanasimus substriatus (Coleoptera: Cleridae) to Ipslures
摘要
Abstract
Field experiments conducted in Aershan forest area,Inner Mongolia,showed that Ipslure 1 attracted much more the clerid predator Thanasimus substriatus (1 319 individuals) than Ips subelongatus (16 individuals).On the contrary,Ipslure 2 attracted much more I.subelongatus (24 104 individuals) than its predators (776 individuals).The biological activities of the two ipslures were further evaluated using electroantennogram (EAG) recording with antennae from I.subelongatus and T.substriatus.The EAG amplitude of I.subelongatus to lpslure 2 (2.139 mV ±0.678 mV females,2.169 mV ± 0.473 mV males) was much stronger than to lpslure 1 (0.440 mV ± 0.232 mV females,0.297 mV ±0.142 mV males).In contrast,the response of T.substriatus to Ipslure 1 (4.618 mV ± 1.106 mV females,4.534 mV ± 1.087 mV males) was much stronger than to Ipslnre 2 (2.209 mV ±0.680 mV females,1.953 mV ±0.601mV males).The EAG results were in agreement with those obtained from field experiments.Gas Chromatography-Mass Spectrometry (GC-MS) analyses showed that Ipslure 1 mainly cis-geraniol ( 3.06％ ),Ipsenol ( 1.98 ％ ),( S ) -cisverbenol (80.36％ ),1-verbenone ( 1.03％ ) and Ipslure 2 consisted of 2-methyl-3-buten-2-ol (4.78％ ),Ipsenol (63.71％),Cedrene (1.46％) and isocaryophillene (22.42％ ).The ipsenol-dominant blend attracted a high number of I.subelongatus while the (S)-cis-verbenol-dominant blend attracted a high number of T.substriatus.The knowledge can be applied for population monitoring and biological control of I.subelongatus.关键词
