Plant extracts for developing mosquito larvicides: From laboratory to the field, with insights on the modes of action

Effects of active edible coating based on thyme and garlic essential oils on lamb meat shelf life after long‐term frozen storage

“…reported a similar profile, with diallyl disulfide (29.1%) and diallyl trisulfide (21.6%), and diallyl trisulfide (33.6%), diallyl disulfide (30.9%) and allyl methyl trisulfide (11.3%) as the major volatile components in samples from Italy and Mexico, respectively. The antimicrobial and insecticidal properties of garlic derivatives have been known from time immemorial …”

“…The antimicrobial and insecticidal properties of garlic derivatives have been known from time immemorial. 36,37 WHC, pH, and color Fresh meat has been reported as showing variations compared with thawed meat due to the frozen storage process. [18][19][20]38 The lack of differences in pH after thawing is consistent with results from Pinheiro et al 19 or Muela et al, 18 who found no differences in pH after 3 to 12 months or 9, 15, or 21 months of freezing.…”

Larvicidal activity of Ocimum campechianum, Ocotea quixos and Piper aduncum essential oils against Aedes aegypti

“…An additional aspect that markedly limits the development of such products for real use is the undeniable lack of field studies validating the efficacy of herbal extracts as mosquito larvicides. Nevertheless, some promising results regarding field experiments have been reported in a recent review article concerning the application of herbal extracts as mosquito larvicides [31]. Herein, at least 14 research studies are mentioned as showing preliminary and encouraging results on the treatment of external water storage reservoirs or sewage water bodies as typical breeding sites for Ae.…”

Larvicidal Efficacy of Fractionated Essential Oils of Tagetes Minuta, Ocimum Kilimandscharicum, and Artemisia Afra Against Anopheles Gambiae S.S.

“…The ever-changing climatic conditions and complex social structures (Cuthbert, et al, 2019), and the development of multiple resistances by mosquito vector species to synthetic insecticides of different classes currently in use (Uragaya, et al, 2015;WHO, 2018), pose a bigger challenge in combating the disease (Pavela, et al, 2019). Prevention and control efforts of human malaria, according to WHO (2018), are threatened by the resistance of the malaria vectors to pyrethroids that are used in all insecticide treated mosquito nets (ITNs), and to the four insecticide classes used for indoor residual spraying (IRS).…”

“…Phytochemicals and their derivatives have been considered potential suitable replacements to synthetic insecticides (Sanei-Dehkordi, et al, 2016), with major research efforts directed towards investigating their insecticidal activity against various developmental stages of the mosquito vectors in a bid to reduce the frequent over reliance on conventional insecticides (Pavela, et al, 2019). Elsewhere, products from Tagetes minuta (Asteraceae), Ocimum kilimandscharicum (Lamiaceae) and Artemisia afra (Asteraceae) have yielded promising efficacy against a number of organisms including the malaria vectors when used alone (Bekele, 2018…”
