Effectiveness of Pleurotus eryngii (King Oyster Mushroom) Extract for Killing Larvae and Attracting Adult Mosquito Vectors in Samut Songkhram Province of Thailand

Abstract

In this study, we assessed the efficiency of Pleurotus eryngii mushroom extract for killing larvae and attracting adult mosquito vectors (Aedes aegypti and Culex sitiens) in the Samut Songkhram province of Thailand. Five extract concentrations (120, 12, 1.2, 0.12 and 0.012 mg/L) were used for larvicidal tests, while 3 concentrations (100, 10, and 1 mg/L) were examined for adult mosquito attraction. The larvicidal results showed that P. eryngii extract did not kill Ae. aegypti larvae, while the extract had minimal effect on Cx. sitiens larvae except at 1.2 mg/L. P. eryngii extract most attracted adult Ae. aegypti and Cx. sitiens mosquitoes at 10 mg/L, followed by 1 and 100 mg/L, respectively. Further, statistical analysis revealed a significantly different number of mosquitoes that responded to P. eryngii extract and octenol. This research demonstrated that this mushroom extract could be developed to attract mosquitoes, although only one concentration (10 mg/L) attracted more than half of all Ae. aegypti adults.

Effectiveness of mosquito magnets for reducing mosquito (Diptera) populations in coastal areas of Samut Songkhram province, Thailand

“…Recently, we have studied the efficiency of a standard mosquito trap, CDC Light Trap, in coastal areas of Samut Songkhram Province [10]. It was found that the trap was able to attract a lot of Culex mosquitos in the areas but it was not efficient enough to control Anopheles mosquitos, the primary vector for malaria.…”

“…Each type of trap has a different price, quality, features, methods of operation, and working mechanisms which must be selected to suit the area for a maximally efficient mosquito control program [9]. In our previous study, we developed a mosquito trap box which was not highly effective for doing the research in coastal areas of Samut Songkhram Province [10]. In addition, we studied the efficiency of the mushroom extracts used to attract mosquitos in the studied areas [7,11].…”

Prevalence and Diversity of Blood Parasites (Plasmodium, Leucocytozoon and Trypanosoma) in Backyard Chickens (Gallus gallus domesticus) Raised in Southern Thailand

“…This lineage was first reported from the Eastern Slaty Thrush (Turdus subalaris, Turdidae, Passeriformes) in Brazil [8], which showed that P. juxtanucleare can spillover from domestic chicken to wild animals. Since P. juxtanucleare has a global distribution, when a suitable temperature is present, not only can the vectors develop but also the parasite can complete its life cycle and be transmitted to the next host, which can be domestic and wild birds [37,58,59]. Southern Thailand may be an excellent environment for the development and transmission of P. juxtanucleare and other vector-borne diseases between wild passerine birds and backyard chickens.…”

Mycochemical screening reveals exopolysaccharide secretion, antioxidant and larvicidal activities of three oyster mushrooms

“…Mushroom alcohol (octenol 1‐octen‐3‐ol) is a volatile organic compound that has been isolated from mushrooms to kill insects 22 . In a study carried out by Chaiphongpachara et al 23,24 . the authors established the mosquitocidal effects of Pleurotus eryngii and Pleurotus pulmonarius .…”
