biostudies-literatureUnknown16(11)Tunon RWhile a great deal of research has been conducted to identify the biotic mechanisms influencing the co-occurrence of aquatic <i>Ae. aegypti</i> and <i>Ae. albopictus</i> mosquitoes, including inter-specific larval competition and mating interference, few studies have been completed to investigate their oviposition behaviors under co-occurrence scenarios. Herein, we performed three experiments to understand the influence of conspecific and heterospecific L4-larvae presence in oviposition by antagonist <i>Aedes</i> spp. mosquitoes. We compared egg counts of <i>Ae. aegypti</i> and <i>Ae. albopictus</i> in cups with water and conspecific or heterospecific larvae (either present or removed), or no larvae as control. In the first experiment, we used small cages; in the second experiment, we usedInsects1110https://www.ebi.ac.uk/biostudies/studies/S-EPMC12653154biostudies-literatureOviposition Behavior of &lt;i&gt;Aedes aegypti&lt;/i&gt; and &lt;i&gt;Aedes albopictus&lt;/i&gt; (Diptera: Culicidae) from Panama Under Experimental L4-Larval Co-Occurrence Scenarios.PMC12653154Kingwell CCastillo ALoaiza JRChong MTunon RRojas ALChaves LFfalseOviposition Behavior of &lt;i&gt;Aedes aegypti&lt;/i&gt; and &lt;i&gt;Aedes albopictus&lt;/i&gt; (Diptera: Culicidae) from Panama Under Experimental L4-Larval Co-Occurrence Scenarios.While a great deal of research has been conducted to identify the biotic mechanisms influencing the co-occurrence of aquatic <i>Ae. aegypti</i> and <i>Ae. albopictus</i> mosquitoes, including inter-specific larval competition and mating interference, few studies have been completed to investigate their oviposition behaviors under co-occurrence scenarios.
