Expression and function of two olfactory-related genes in response to methyl salicylate in the wolf spider Pardosa pseudoannulata (Araneae: Lycosidae)

  Expression and function of two olfactory-related genes in response to methyl salicylate in the wolf spider Pardosa pseudoannulata (Araneae: Lycosidae) The wolf spider ( Pardosa pseudoannulata ) is common in rice fields. Olfaction is crucial for perceiving chemical information, and our previous research indicated that methyl salicylate (MeSA), a common herbivore-induced plant volatile (HIPV), significantly attracts P. pseudoannulata . However, few studies have examined the functions of spiders' olfactory-related genes and their interactions with HIPVs. This study aimed to identify olfactory-related genes associated with MeSA in P. pseudoannulata . Transcriptome analysis revealed four differentially expressed olfactory-related genes in response to MeSA in P. pseudoannulata . Subsequent molecular docking analysis indicated that MeSA had a strong predicted binding affinity with proteins of two key olfactory-related genes ( PpseNPC2-7 and PpseSNMP2 ). These two genes were cloned, and...

Distribution of Trichonephila clavipes (Linnaeus, 1767) (Araneae: Araneidae) in Honduras

ABSTRACT

Trichonephila clavipes is recorded for the first time in the department of Francisco Morazán, from a female specimen collected on the campus of the Universidad Nacional Autónoma de Honduras (CU-UNAH), in Tegucigalpa, Honduras. We also present additional records of males and females collected in the city of La Ceiba (department of Atlántida) and on the island of Útila (department of Islas de la Bahía). To complement the distribution, we included in a map 200 records obtained from the citizen science platform iNaturalist.
