Abstract: Temperature is a critical factor of insect population abundance and distribution. Monochamus alternatus Hope (Coleoptera: Cerambycidae) is a significant concern since it is transmitted vector of the pinewood nematode posing enormous economic and environmental losses. This pest shows tolerance to heat stress, especially extremely high temperatures. Exposing for 6, 12, 24, 48, or 96 h, the 50% median lethal temperatures (Ltem 50) for fourth-instar larvae were 47.5, 45.5, 43.9, 43.4, and 42.3 • C, respectively. A… Show more

“…The larvae of M. alternatus were obtained from infested host trees ( Pinus massoniana ) in Jiujiang, Jiangxi Province, China and reared individually on an artificial diet at a constant temperature of 25 ± 0.5°C under a relative humidity (RH) of 60 ± 5% as described by our previous experiment (Li et al ., 2020). Once emergence, adults were individually provided with fresh 1- to 2-year-old P. massoniana twigs.…”

“…M. alternatus showed strong heat tolerance in our previous study (Li et al ., 2020). Only appropriately 50% of the M. alternatus population was deadly damaged when exposed to 42.5°C for 96 h and almost all individuals could endure 40°C for 96 h. This property, in M. alternatus , was achieved for a broad array of adaptive strategies against adverse high temperature, c overing ecological, behavioral, and physiological aspects.…”

“…The pinewood nematode, which is vectored by the pine sawyer beetle M. alternatus , is native to North America and is not considered a primary pathogen of native pines but is the cause of pine wilt in some non-native species [ 41 ]. Using global transcriptome information from previous studies that analyzed the response of M. alternatus to heat stress and pesticides [ 27 , 42 ], a recent comparative study expanded these findings by probing immune-related gene transcript changes in M. alternatus infected by B. xylophilus parasites [ 43 ]. Using high-throughput Illumina RNA-Seq, it was thoroughly demonstrated that the presence of B. xylophilus in M. alternatus adults alters the expression profile of a large number of genes with known or putative immune function.…”
