“…Indeed, increases in the activity of detoxifying enzymes (e.g. glutathione‐S‐transferases, esterases, cytochrome‐P450 dependent monooxygenase) have been reported for target pests, including aphids and lepidopteran defoliators, that have been exposed to sublethal doses of botanical insecticides.…”

Biorational insecticides are composed of natural products, including animals, plants, microbes, and minerals, or are their derivates. The use of biorational products for the management of insect pests has grown intensively in recent years, which has increased their popularity and share on the insecticide global market. Much of these recent increases in the use of biorational insecticides has been derived from the generalized perception that conventional insecticides have undesirable ecological and human health impacts. However, the idea of simply replacing synthetic compounds with biorational insecticides without considering their potential unintended effects can mislead their use and reduce the market life of such pest management tools. A systematic literature survey encompassing over 15 000 scientific manuscripts published between 1945 and 2019 reinforces the bias of focusing on studying the targeted effects while overlooking the potential detrimental effects of biorational products on human health and the environment (e.g. death and negative sublethal effects on pollinators and beneficial arthropods such as parasitoids and predators). Thus, the risks associated with biorational compounds (e.g. control failures, the evolution of resistance, shift in dominance, and outbreaks of secondary or primary pests) need to be revisited and the outcomes of such inquiry could be decisive for their future use in pest management programs. The shortcomings of regulatory processes, knowledge gaps, and the outlook for the use of the biorational products in pest management are discussed.

“…The infestation of these two insect pests very 26 easily occurs, mainly because they have developed multiple resistances to commonly used 27 conventional agrochemicals resulting in population outbreaks, affecting yields of maize, 28 wheat, rice and some crucifer crops. [1][2][3][4][5][6][7] Consequently, the search for new potential alternatives 29 to effectively and selectively control insect pests has recently received considerable attention 30 in the agricultural field. 8-18 31 Fraxinellone, 1 (Figure 1), a degraded limonoid, exhibited interesting pesticidal 32 activities.…”

A total of 20 esters of fraxinellone C4/10-oxime were synthesized and determined by melting points, optical rotation, infrared spectra, proton nuclear magnetic resonance spectra, and high-resolution mass spectrometry spectra. Two steric configurations of compounds 7i and 8i were unambiguously confirmed by X-ray crystallography. Additionally, their pesticidal activities were assessed on two typical lepidopteran pests, Mythimna separata Walker and Plutella xylostella Linnaeus. Generally, all compounds exhibited less potent oral toxicity than toosendanin against third-instar larvae of P. xylostella. However, all compounds showed the growth inhibitory property against early third-instar larvae of M. separata. Notably, compounds 7m, 8b, 8k, 9, and 11 displayed more potent pesticidal activity than toosendanin. This demonstrated that introducing the C-4 carbonyl or oxime group on fraxinellone resulted in more promising derivatives than those bearing a C-10 carbonyl or oxime substituent.

“…The chemical composition of DA‐EO specimens collected in different countries has been the subject of several studies . Although the content and composition of DA‐EO may vary greatly among specimens collected from different regions and plant parts, in distinct seasons, few constituents have been identified other than the monoterpenes p ‐cymene, α ‐terpinene, limonene, carvacrol, ascaridole, and trans ‐isoascaridole, which collectively represent the major portion of DA‐EO . According to Muhayimana and coworkers, the chemical composition of the essential oil of D. ambrosioides can be divided into three categories: i ) oils with high concentration of ascaridole (70 – 91%), common in chemotypes from North America; ii ) oils in which ascaridole is main constituent of the mixture (20 – 67%), which also contains other non‐oxygenated monoterpenes that are common in chemotypes from India, Brazil, Argentina and Russia; and iii ) oils with high concentration of α ‐pinene (30 – 32%), pinocarveol (40 – 42%), and/or pinocarvone (62 – 65%) .…”

“…In folk medicine, D. ambrosioides is widely used as vermifuge . The use of D. ambrosioides extracts and infusions as anthelmintic and antileishmanial agents has also motivated studies on the antiparasitary activity of this species against different microorganisms, such as helmints and protozoa . With regard to the schistosomicidal action of D. ambrosioides , only the effects of methanol extracts have been investigated to date .…”

We have investigated the chemical composition and the antibacterial activity of the essential oil of Dysphania ambrosioides (L.) Mosyakin & Clemants (Chenopodiaceae) (DA-EO) against a representative panel of cariogenic bacteria. We have also assessed the in vitro schistosomicidal effects of DA-EO on Schistosoma mansoni and its cytotoxicity to GM07492-A cells in vitro. Gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS) revealed that the monoterpenes cis-piperitone oxide (35.2%), p-cymene (14.5%), isoascaridole (14.1%), and α-terpinene (11.6%) were identified by as the major constituents of DA-EO. DA-EO displayed weak activity against Streptococcus sobrinus and Enterococcus faecalis (minimum inhibitory concentration (MIC) = 1000 μg/ml). On the other hand, DA-EO at 25 and 12.5 μg/ml presented remarkable schistosomicidal action in vitro and killed 100% of adult worm pairs within 24 and 72 h, respectively. The LC values of DA-EO were 6.50 ± 0.38, 3.66 ± 1.06, and 3.65 ± 0.76 μg/ml at 24, 48, and 72 h, respectively. However, DA-EO at concentrations higher than 312.5 μg/ml significantly reduced the viability of GM07492-A cells (IC = 207.1 ± 4.4 μg/ml). The selectivity index showed that DA-EO was 31.8 times more toxic to the adult S. mansoni worms than GM07492-A cells. Taken together, these results demonstrate the promising schistosomicidal potential of the essential oil of Dysphania ambrosioides.
