One to understudied reason for larval competition ‘s the part regarding mosquito oviposition behavior
To ensure that larval battle so you can like Ae. albopictus over Ae. aegypti, both species have to basic deposit their egg (oviposit) in identical bins. Mosquitoes don’t prefer oviposition internet randomly; as an alternative, they address multimodal cues to choose well-known environment [fourteen,15,16,17]. When the Ae. albopictus positively search or prevent oviposition websites in accordance with the visibility or absence of Ae. aegypti otherwise Ae. albopictus larvae, this will boost or decrease the level of battle. However, experiments so far has mainly started laboratory-oriented [18, 19] or observational [seven, 20]. There is you to definitely had written open-field-established learn from just how oviposition website taste can affect interspecific larval race. This research compiled naturally occurring eggs when you look at the bins that have drinking water made use of to help you in earlier times bottom differing levels of pre-current conspecific and you can heterospecific larval thickness , and found facts these particular products normally drive Ae. albopictus oviposition website incorporate. Yet not, the fresh new guidance associated with the preference are uncertain.
I presented an experiment to check on brand new theory you to definitely Ae. albopictus oviposition website attraction inside Medellin Medellin, Colombia, try driven because of the exposure, occurrence, and you will types of often conspecific or heterospecific Ae. aegypti larvae regarding the marine habitat. When you find yourself research tests control to own environment variability, they cannot always be extrapolated to the profession, although observational training and you can pure collections review of true standards, the build will make it difficult to pinpoint the best reason behind observed habits.
