AI Article Synopsis

  • Different mosquito species show varying resistance levels to synthetic insecticides like temephos, sparking interest in alternative insecticides such as semi-synthetic dillapiole butyl ether.
  • Dillapiole butyl ether has shown effective ovicidal and larvicidal properties without significant risks of mutagenicity or cytotoxicity for humans and other vertebrates in drinking water.
  • Testing on Balb/C mice indicated that dillapiole butyl ether only induced genetic damage at high concentrations (40 mg/kg), suggesting lower concentrations (10 and 20 mg/kg) could be safe and effective for mosquito control.

Article Abstract

and are vectors of arboviruses and have different levels of resistance to synthetic insecticides, such as the organophosphate temephos, according to their area of occurrence. As an alternative, there are semisynthetic substances with potential insecticidal effect; however, they need to be fully tested by an effective method for the mosquito control. The semi-synthetic dillapiole butyl ether exhibits toxic ovicidal and larvicidal activity in both mosquito species. However, has no proven the mutagenicity and cytotoxicity risks of this larvicide in drinking water effect for consumption by non-target organisms, such as in humans neither in other vertebrates, which access pools of water contain this sprayed substance. In this sense, both of the biomarkers of the genotoxicity, the micronucleus (MN) and comet, using this substance were tested in Balb/C mice to assess the genetic damage and risks of its application as a mitigating measure against . Male specimens (n = 60) were exposed to dillapiole -butyl ether at concentrations of 10, 20 and 40 mg/kg via a comet assay in peripheral blood (n = 30) and a micronucleus test in bone marrow cells (n = 30). The induction of mutagenicity and cytotoxicity of dillapiole -butyl ether in these animals occurred only at a concentration of 40 mg/kg, in multiple treatments. However, dillapiole n-butyl ether at concentrations of 20 and 10 mg/kg has potential for use against in the form of a larvicide in water for consumption by humans and other vertebrates a new vector control measure.

Cutaneous leishmaniasis (CL) is considered a public health problem. Current treatments have disadvantages because they are invasive and have serious side effects, and thus there is a need for research into new, more effective pharmacological alternatives. Plants are promising sources of bioactive substances, and new analogues can be obtained through chemical reactions.

Dillapiole -butyl ether is a substance derived from dillapiole, which exhibits potential insecticidal effects on , the principal vector of the Dengue fever, Zika, and Chikungunya viruses, as well as , a vector of Dengue fever. As these mosquitoes are resistant to synthetic insecticides, dillapiole -butyl ether may represent a valuable, plant-based alternative for their control. Dillapiole -butyl ether has insecticidal and genotoxic effects on and , as shown by the reduction in clutch size and egg viability, and increased mortality rates, as well as a high frequency of micronuclei and chromosomal aberrations.

Two derivatives of dillapiole, dillapiole ethyl ether (1KL39-B) and butyl ether-n dillapiole (1KL43-C), were studied for their toxicity and genotoxicity against Aedes albopictus, to help develop new strategies for the control of this potential vector of dengue and other arboviruses, because it is resistant to synthetic insecticides. Eggs and larvae exposed to different concentrations of 1KL39-B (25, 30, 50, 70, and 80μg/mL) and of 1KL43-C (12.5, 20, 25, 30 and 40μg/mL) exhibited toxicity and susceptibility, with 100% mortality.

The effects of two semi-synthetic dillapiole derivatives, ethyl-ether dillapiole and n-butyl ether dillapiole, on eggs and larvae of Aedes aegypti were studied in view of the need for expansion and renovation of strategic action to control this mosquito - the vector of Dengue virus -, which currently shows a high resistance to chemical insecticides. Eggs and third-instar larvae of A. aegypti that had been exposed to different concentrations of these two compounds showed toxicity and susceptibility, with 100% mortality.
