“…However, in previous studies, the acute toxicity of the A. citrodora EO was tested against the larvae of the mosquitoes Aedes aegypti L., Anopheles stephensi Liston, and Culex quinquefasciatus Say (Diptera: Culicidae) in water, with LC 50 values ranging between about 10-100 ppm [55,56]. Similarly, Leyva et al [57] recently tested the larvicidal effect of a B. graveolens EO, extracted from leaves, on Ae. aegypti, Aedes albopictus (Skuse) (Diptera: Culicidae), and C. quinquefasciatus.…”

Blowflies are vectors of microorganisms and human pathogens, and their maggots cause myiasis in vertebrates and infest and spoil meat and fish products. Essential oils (EOs) from spices were proven to be a safer and more sustainable alternative to synthetic insecticides for the control of blowflies and are suitable for protecting food from such pests. However, some EOs are not acceptable for environmental or topical applications due to their strong, unpleasant odour. In this study, we measured the acute toxicity and the repellence of two EOs extracted from the Andean plants Aloysia citrodora Palau and Bursera graveolens (Kunth) Triana and Planch., both known for their pleasant odour, against the blue blowfly Calliphora vomitoria (L.) (Diptera: Calliphoridae). We also compared their bioactivity with that of the Allium sativum L. EO, which is very effective but bad-smelling. The A. citrodora EO was mainly rich in oxygenated monoterpenes, the most abundant of which were geranial (26.8%) and neral (21.0%). The B. graveolens EO was chiefly composed of monoterpene hydrocarbons, mostly represented by limonene (46.2%). According to the sensory description, the best odour profile was associated with the A. citrodora EO, while the olfactory expression of the EO from B. graveolens was negatively affected by a strong odour of “mouldy lemon”. The behavioural test showed that the A. citrodora EO was more repellent than that of A. sativum and, on the contrary, that the B. graveolens EO was attractive. The toxicity tests showed that the EOs of both Andean plants have a clear toxic effect on the C. vomitoria eggs and adults. In terms of ovicidal activity, there were no significant differences among the effects of the three tested EOs. On the adult flies, the toxicity of the two EOs of the Andean plants was much lower than that of A. sativum (LC50 fumigation = 1.86 μL EO L−1 air; LC50 ingestion = 8.10 μL EO mL−1 gel) both by fumigation (LC50 = 23.66 and 25.30 μL EO L−1 air for A. citrodora and B. graveolens, respectively) and ingestion (LC50 = 36.65 and 44.97 μL EO mL−1 gel for A. citrodora and B. graveolens, respectively), while, by contact, the A. citrodora EO (LD50 = 0.27 μL EO insect−1) was more toxic than the A. sativum EO (LD50 = 0.46 μL EO insect−1).

“…Descamps et al [40] found that the essential oil of E. globulus, at a concentration of 7% w/v, was non-attractive for Acyrthosiphon pisum Harris (Hemiptera: Aphididae) adults. The main bioactive compounds present in E. globulus are ρ-cymene, γ-terpinene, and 1.8 cineol (eucalyptol), and the synergistic activity of these and other compounds are responsible for the elaborated action of the E. globulus plants on different species of the insects [41]. In the present work, the aqueous extract of the E. globulus was not attractive to M. spectabilis as compared to clean air; however, when compared to the host plant combination, there was no change.…”

Olfactory Response of Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) to Volatile Aqueous Extracts of Plant Origin Applied to Elephant Grass Plants (Pennisetum purpureum Schum)

In this study, we evaluate the olfactory responses of Mahanarva spectabilis adults to aqueous extracts from the following non-host plants for the pest insect: garlic (Allium sativum L.), rue (Ruta graveolens L.), cinnamon (Cinnamomum verum J. Presl), lemongrass (Cymbopogon citratus Stapf.), clove (Syzygium aromaticum L.), star anise (Illicium verum Hook.f), eucalyptus (Eucalyptus globulus Labill.), tobacco (Nicotiana tabacum L.), and thyme (Thymus vulgaris L.) applied to the host plant, elephant grass (Pennisetum purpureum Schum.). The bioassays were performed using a Y olfactometer, and the combinations of the plant extracts applied to the host plant were tested against fresh air and against the host plant without the extract. The results show that the extracts of tobacco and star anise were non-attractive to M. spectabilis adults. The extracts from the remaining plants did not alter the response of M. spectabilis to the host plant.

“…(Lamiaceae) revealed that the compound aromadendr-1(10)-en-9-one (30.7%) was the major constituent [ 7 ], while a similar study reported that cadin-4,10(15)-dien-3-one (14.8%) and isocaryophyllene epoxide (14.4%) were the most abundant compounds in the Cuban variety [ 8 ]. Selective ecological pressures over centuries have led plants to produce secondary metabolites to combat and defend against herbivorous insects [ 9 ]; therefore, it is not surprising that increased toxic activity is sometimes observed when local plant extracts are used as insecticides against some local insect species [ 10 ].…”

Larvicidal Potential of Caribbean Plants

Mosquitoes are vectors for numerous arboviruses such as dengue, chikungunya, and Zika which continue to negatively impact the health of Caribbean populations. Within the region, synthetic insecticides are primarily used to control mosquito populations. In many countries however, these compounds are becoming less effective due to resistance, and they may also be harmful to the environment. Thus, there is a significant need for the development of alternative agents to combat the mosquito threat in the Caribbean. Worldwide, botanical-based products are being increasingly investigated for vector control because they are environmentally friendly and are often highly effective mosquitocidal agents. Although the botanical diversity within the Caribbean is remarkable, work on plant biopesticides in the region remains limited. The aim of this review, therefore, is to discuss the use of Caribbean botanical extracts as larvicidal agents. Additionally, we highlight the need for future work in this area which may subsequently lead to the implementation of transformative public health policies.
