Evaluation of Cymbopogon flexuosus and Alpinia zerumbet essential oils as biopesticides against Callosobruchus maculatus

Toxicity, Behavioral Effects, and Chitin Structural Chemistry of Reticulitermes flaviceps Exposed to Cymbopogon citratus EO and Its Major Constituent Citral

“…Piperitone (59.2-71.5%) [15,17], α-eudesmol (17.89%) [18], and cis-p-Menth-2-en-1-ol (28.5%) [24] were the major components in C. schoenanthus oil. The major components of C. flexuosus oil were neral (30.4%) [10] and geranial (38.44%) [25]. A previous study reported that citronellal (24.0-55.4%) [19,26] was the main constituent in C. winterianus oil.…”

“…According to previous reports, Cymbopogon EOs present good insecticidal activity against vector pests, such as Anopheles funestus [27], Aedes aegypti [28,29], Aedes albopictus [30], Cochliomyia hominivorax [31], Culex quinquefasciatus [32], Haemaphysalis longicornis [33], Musca domestica [34], Rhipicephalus microplus [35], and Sarcoptes scabiei [36]; storage pests, including Acanthoscelides obtectus [37], Callosobruchus maculatus [25,38,39], Dinoderus porcellus [22], Rhyzopertha dominica [40], Sitophilus granaries [41], Sitophilus oryzae [42][43][44], Sitophilus zeamais [45,46], Tenebrio molitor [47], Trogoderma granarium [48], Tribolium castaneum [49][50][51][52][53], and Ulomoides dermestoides [23,54]; and agricultural insect pests, such as Bemisia tabaci [55], Euprosterna elaeasa [56], Megalurothrips sjostedti [57], Phthorimaea operculella [58], Spodoptera exigua [59], Spodoptera frugiperda [60,61], Trichoplusia ni [62,63], and Tuta absoluta [64].…”

Phytochemicals of Alpinia zerumbet: A Review

“…The essential oils of A. zerumbet mainly include monoterpenes, oxygenated monoterpenes, and oxygenated sesquiterpenes [ 123 ]. According to the previous 35 studies [ 2 , 4 , 8 , 14 , 18 , 31 , 34 , 36 , 37 , 38 , 41 , 47 , 49 , 51 , 52 , 53 , 54 , 70 , 74 , 87 , 92 , 96 , 97 , 124 , 125 , 126 , 127 , 128 , 129 , 130 , 131 , 132 , 133 , 134 , 135 ], the relative contents of the 33 major volatile components in the essential oils prepared from the leaves [ 2 , 4 , 8 , 14 , 31 , 34 , 36 , 37 , 38 , 41 , 47 , 49 , 51 , 52 , …”

“…The chemical constituents of the essential oils obtained from the leaves of A. zerumbet have been frequently reported [ 2 , 4 , 8 , 14 , 31 , 34 , 36 , 37 , 38 , 41 , 47 , 49 , 51 , 52 , 53 , 54 , 70 , 124 , 125 , 126 , 127 , 128 , 129 , 130 ]. In 1984, Luz et al [ 124 ] investigated the composition of the essential oils in A. zerumbet leaves collected 60 km from Manausare (Brazil) and identified p -cymene (9.4%), 1,8-cineol (14.9%), γ-terpinene (9.5%), and 4-terpineol (20.4%) [ 124 ].…”

“…Cavalcanti et al [ 41 ], Cunha et al [ 34 ], de Carvalho Castro et al [ 31 ], Gomes et al [ 51 ], and Rocha et al [ 54 ] clarified p -cymene, 1,8-cineol, and terpinen-4-ol as the main components of the essential oils from A. zerumbet leaves collected in Brazil. Other studies have revealed the chemical compositions of the essential oils derived from A. zerumbet leaves collected from Belém City, State of Pará (Brazil) in May 1997 [ 2 ], Rio de Janeiro (Brazil) [ 125 ], Núcleo de Pesquisas de Produtos Naturais (Brazil) [ 126 ], the municipality of Baturité (Brazil) in March 2010 [ 37 ], the Botanical Garden of the Universidade Federal Rural do Rio de Janeiro (GPS: 22°31′36.23 S, 44° 04′31.62 W) (Brazil) [ 127 ], Bacabal City, State of Maranhão (GPS: 4°13′2″ S, 44°46′60″ W) (Brazil) [ 52 ], and the Medicinal Plants Garden of the Federal University of Lavras (GPS: 21°12′4″ S, 44°57′58″ W) (Brazil) in September 2018 [ 128 ].…”
