“…Fumigant toxicity of some EOs extracted from Iranian rosemary ( Rosmarinus officinalis L.), squaw mint ( Mentha pulegium L.), satar ( Zataria multiflora Boiss ), and sweet orange ( Citrus sinensis L.) on adults of stored‐product pests, including T. castaneum Herbst , Sitophilus granarius Linnaeus , C . maculatus Fabricius , and Plodia interpunctella Hubner has also been reported . The toxicity of the EO which was both concentration‐ and exposure duration‐dependent agrees with previous studies on some stored product insects …”

Due to several ecological and human hazards of synthetic pesticides in postharvest crop protection, there is the need to search for eco-friendly alternatives. In this study, chemical composition and insecticidal activities of essential oil (EO) obtained from Hoslundia opposita dried leaves were evaluated against cowpea seed bruchid. Eight constituents, predominated by oxygenated monoterpenes (78.86%), were identified using Gas Chromatography (GC)/MS. The constituents were 1,8-cineole (1; 61.15%), followed by α-terpineol (2; 16.81%), β-phellandrene (3; 13.24%), β-farnesene (4; 3.55%), α-pinene (5; 1.89%), Germacrene D (6; 1.83%), cis-sabinene hydrate (7; 0.90%) and caryophyllene (8; 0.63%). In fumigation bioassay, at 6 h after exposure (HAE), 0.78 ml EO/l air caused 35.33% mortality which was significantly lower than 60.90% and 63.6% observed at 3.15 and 6.25 ml/l air, respectively. Mortality reached 90.0% at 24 HAE regardless of the applied concentration. Lethal time for 50% of the bruchids (LT ) at concentration of 0.78 ml/l air (6.89 h) was higher than the LT at 3.15 and 6.25 ml/l air (4.72 and 4.44 h, respectively). H. opposita EO reduced Callosobruchus maculatus oviposition, while progeny emergence observed in EO-treated seeds (2.42 - 25.73) was significantly (P < 0.05) lower than 51.56 observed in control. The results confirm H. opposita EO's potentials for control of cowpea bruchids.

“…The act of weakening of adults by botanical powders may make them lay fewer eggs than the normal leading to less hatchability to larvae and final metamorphosis to adults. Different botanicals effectiveness at higher dosage to various storage insect pests have been reported by several authors (Huang et al, 2000;Tripathi et al, 2000;Adedire and Lajide, 2003;Akinkurolele et al, 2006;Mbailao et al, 2006;Wang et al, 2006;Negahban et al, 2007;Oni and Ileke, 2008;Shahaf et al, 2008;Ayvaz et al, 2010;Bachrouch et al, 2010;Sivakumar et al, 2010;Adedire et al, 2011;Ileke and Oni, 2011;Mahmoudvand et al, 2011).…”

In storage, maize grains are severely destroyed by insects and other storage pests. One of the primary causes of grain loss in stored maize is the damage caused by maize weevil, Sitophilus zeamais. A study was conducted to evaluate selected locally available botanical powders and cooking oils for their effectiveness as grain protectants against maize weevils at JUCAVM in year 2011. The plant powders and cooking oils were compared with untreated control and Malathion super dust as standard check. The experiment was laid-out in Completely Randomized Design with 13 treatments each replicated thrice. Different dependent variables such as cumulative adult mortality, F 1 progeny emergency, grain damage were assessed. The results revealed that, among the botanical powders, there was an increased cumulative adult S. zeamais mortality, i.e. higher mortality, from powders of Chenopodium ambrosoides (70% with LT 50 of 6.50 days), Azadiricta indica leaf (70% with LT 50 of 6.00 days), A. indica bark (70% with LT 50 of 8.40 days) and Tagetus erecta (70% with LT 50 of 9.20 days) after 20 days of exposure periods. Apart from the untreated control, low mortality of S. zeamais adult was recorded from Allium sativum (50% with LT 50 of 18.01 days), C. citratus (55% with LT 50 of 18.30 days), Maesa lanceolata (55% with LT 50 of 16.20 days) and Echinops kebericho (55% with LT 50 of 14.50 days) after 20 days of exposure periods. Highest S. zeamais adult mortality of 95%, 100% and 100% was recorded from Brassica carinata oil, Gossypium hirsutum oil and the standard chemical Malathion, respectively with LT 50 of less than one day in all cases. Maximum number of progeny was emerged from untreated check from 25 th~4 0 th days of exposures with cumulative increase (2 to 14 adults). There was no F 1 progeny emergency from the three treatments (oils and Malathion) over the exposure periods reassuring the potency of the cooking oils against S. zeamais. As a result there was no perforated seed; no weight loss and maximum germination percentage of 94.60% were registered from the two cooking oils on par with the Malathion (95.50%). In conclusion, the two cooking oils were found to be the most potent bio-insecticides on par with standard check, Malathion and they can be used in integrated management of maize weevil, S. zeamais.

“…(Myrtaceae) (LC 50 between 7 and 8.5 μL/L) [55,56], and Citrus limon (Rutaceae) (LC 50 � 9.89 μL/L) [20] were particularly effective against S. oryzae adults applied as fumigant. Regarding other curculionid weevils, again Lamiaceae revealed to be very effective as fumigant (i.e., Origanum acutidens and Mentha pulegium against S. granarius [57,58] and D. moldavica against S. zeamais [25]). Notably, also the EO from fruits of a plant belonging to the Lauraceae family, L. salicifolia, showed high insecticidal properties against S. zeamais when employed in fumigation trials (LC 50 � 4.4 μL/L) [26].…”

Among botanical extracts used as insecticides, essential oils (EOs) are promising alternatives to chemical insecticides. EOs are synthesized by plants, and they play a key role in plant signaling processes including also attractiveness toward pollinators and beneficial insects. Plant species producing essential oils (over 17,000 species) are called aromatic plants and are distributed worldwide. Our review aims to evaluate research studies published in the last 15 years concerning the use of EOs in stored product protection. More than 50% of the retrieved manuscripts have been published by authors from Eastern countries (Iran, China, India, and Pakistan), investigating different aspects related to insect pest management (exposure route, effect on the target pest, and mode of action). Coleoptera was the most studied insect order (85.41%) followed by Lepidoptera (11.49%), whereas few studies targeted new emerging pests (e.g., Psocoptera). Almost all the trials were carried out under laboratory conditions, while no experiments were conducted under real operating conditions. Future research studies concerning the use of EOs as insecticides should focus on the development of insecticide formulations which could be successfully applied to different production realities.
