What specific compounds found in mango leaves are known to attract mosquitoes?5 answersCompounds found in mango leaves that are known to attract mosquitoes include humulene, (E)-caryophyllene, terpinolene, and myrcene. Additionally, volatile organic compounds like α- and β-pinene have been linked to attracting the mango gall fly to susceptible cultivars. Furthermore, 1-octen-3-ol, ethyl tiglate, and benzothiazole have been identified as oviposition stimulants for the oriental fruit fly, Bactrocera dorsalis, which is attracted to mango fruits. These compounds play a crucial role in the oviposition site selection by female B. dorsalis. Moreover, mosquito attractant formulations may include aldehyde components, monoterpene components, and the compound HMBPP as a phagostimulant. Overall, these compounds found in mango leaves play significant roles in attracting mosquitoes and other insects to the plant.
Are women more likely to suffer from allergic reactions to stings and bites than men?4 answersWomen are not necessarily more likely to suffer from allergic reactions to stings and bites compared to men. Research indicates that in cases of Hymenoptera venom allergy, which can lead to severe systemic reactions, there were 281 women and 217 men affected, showing a relatively balanced distribution. Additionally, systemic allergic reactions after insect stings, particularly caused by Hymenoptera, can vary in prevalence based on the severity of previous reactions, with a range of 5% to 65% in individuals with different histories of reactions. Therefore, the likelihood of allergic reactions to stings and bites is more dependent on individual factors such as previous reactions and sensitization rather than gender.
How does the attractiveness of mango leaves to mosquitoes compare to other natural attractants?5 answersMango leaves exhibit varying levels of attractiveness to mosquitoes compared to other natural attractants. Research shows that mango leaf infusions, along with rambutan and cashew leaves, were effective in attracting Aedes aegypti mosquitoes in lethal ovitraps, with cashew leaf infusion and rambutan leaf ethanol extract being particularly successful. Additionally, volatile compounds from mango juice baits attracted Anopheles gambiae mosquitoes, with specific compounds like humulene and terpinolene being highly attractive. In contrast, studies on the Mexican fruit-fly found that handcrafted traps with natural baits like pineapple and guava were comparable in attractiveness to commercial baits like Captor 300. Furthermore, the olfactory preference of Anastrepha obliqua for mango cultivars was influenced by the ripeness stage and specific volatile compounds present in the fruits.
Are men more likely to get malaria than women?5 answersMen are more likely to get malaria than women. This is because women are more likely to be exposed to malaria infections due to their prolonged exposure to mosquito bites during the most dangerous hours. Additionally, a study found that most malaria cases were women, who had more external risk factors associated with infection. However, it is important to note that other factors such as age and number of infectious mosquito bites received also play a role in the acquisition of immunity to malaria.
What are the most effective scents for repelling mosquitoes?5 answersThe most effective scents for repelling mosquitoes include folium artemisiae argyi, clove oil, citronella oil, lavender oil, and jasmine flower fragrance. These scents have been found to repel mosquitoes and have long-lasting effects. Additionally, the essential oils obtained from Monodora myristica and Xylopia aethiopica plants have shown insecticidal potential against mosquito vectors. The combination of herba artemisiae apiaceae oil and essence has also been found to have a strong mosquito-repellent effect. Furthermore, the jasmine flower fragrance in a mosquito-repellent liquid has been proven to be effective in repelling mosquitoes. Overall, these scents offer natural and safe alternatives for mosquito repellents, with the potential to provide long-lasting protection against mosquito bites.
What are the bloodmeal sources of mosquitoes?5 answersMosquitoes have a diverse range of bloodmeal sources, including humans, birds, mammals, and other vertebrates. Studies have shown that the bloodmeal sources of mosquitoes can impact their feeding rates, adult survival, fecundity, hatching rates, and developmental times. Different methods have been used to identify the bloodmeal sources, such as serological techniques, host DNA amplification, and mass spectrometry. The identification of bloodmeal sources has also revealed important asymmetries in mosquito attraction towards different host species. For Anopheles mosquitoes, which are the primary vectors of malaria, bloodmeal type has been found to have a strong impact on mosquito feeding rate, survival, lifetime fecundity, and offspring size. In the case of Culex mosquitoes, which are important for maintaining mosquito-borne viral diseases, bloodmeal sources have been identified as wild boar, heron, and avian species. Overall, understanding the bloodmeal sources of mosquitoes is crucial for understanding their ecology and their role in the transmission of diseases.
