“…This was because the weevils had no escape route from the experimental unit, and so, the longer the period of exposure, the higher the toxic effect of the EO that penetrated into their body systems. This agrees with Lira et al (2015) who reported the fumigant toxicity of EO from Alpinia purpurata inflorescences against S. zeamais. The observation was also in line with Babarinde et al (2014) who reported the fumigant toxicity of the EO obtained from the freshly harvested H. opposita leaves against T. castaneum.…”

Botanical essential oils (EOs) are effective alternatives to over-dependence on synthetic insecticides in stored product protection. However, the burden of handling bulky fresh botanicals needed for EO extraction and the tendency of the freshly harvested botanical to rot in transit, if wrongly handled, can be bottlenecks to pilot scale application of EO. Therefore, this study evaluates the comparative efficacy of the EOs obtained from freshly harvested Hoslundia opposita Vahl (Lamiaceae) and plants exposed to different shade-drying regimes (1-5 days) against maize weevil, Sitophilus zeamais Motschulsky, under laboratory conditions. Evaluation included fumigant toxicity and repellence bioassays. At 2 hours after exposure (HAE), EO of freshly harvested H. opposita leaves caused significantly (P <0.001) lower mortality (53.30%) than the value observed in H. opposita leaves dried for 5 days (90.00%). The lethal time for 90.00% of the weevils (LT 90 ) obtained in EO from H. opposita leaves dried for 5 days (2.00 h) was significantly lower than 2.80 and 7.14 h obtained in EOs from the fresh and 1 day-dried leaves, respectively. At 1 HAE, EOs obtained from H. opposita leaves dried for 4 and 5 days caused 60.00% repellence which was significantly higher than 20.00% observed in fresh leaves. At 2 HAE, EOs obtained from H. opposita dried for 4 and 5 days caused significantly higher repellence (100.00 and 80.00%, respectively) than what was observed in fresh leaves (70.00%). The results imply that shade drying freshly harvested H. opposita leaves has no deleterious effects on the efficacy of its EO against maize weevil.

“…In our previous investigation, the same parsley fruit EO caused significant anti-nutritional effects (feeding and growth inhibition with weight loss) to the caterpillar Pseudaletia unipuncta (Lepidoptera: Noctuidae) (Sousa et al ., 2015 a ). Evidences of EOs activities on the maize weevil feeding behaviour and nutrition, with significant reduction of the nutritional indices and moderate antifeedant effects, have been reported for several plant species, namely nutmeg ( Myristica fragrans , Myristicaceae) (Huang et al ., 1997), Evodia rutaecarpa (Rutaceae) (Liu and Ho, 1999), cardamom ( Eletaria cardamomum, Zingiberaceae) (Huang et al ., 2000) and red ginger ( Alpinia purpurata , Zingiberaceae) (de Lira et al ., 2015). However, investigations concerning Apiaceae EOs are scarce.…”

Sitophilus zeamais is a key pest of stored grains. Its control is made, usually, using synthetic insecticides, despite their negative impacts. Botanical insecticides with fumigant/repellent properties may offer an alternative solution. This work describes the effects of Anethum graveolens, Petroselinum crispum, Foeniculum vulgare and Cuminum cyminum essential oils (EOs) and (S)-carvone, cuminaldehyde, estragole and (+)-fenchone towards adults of S. zeamais. Acute toxicity was assessed by fumigation and topical application. Repellence was evaluated by an area preference bioassay and two-choice test, using maize grains. LC50 determined by fumigation ranged from 51.8 to 535.8 mg L−1 air, with (S)-carvone being the most active. LD50 values for topical applications varied from 23 to 128 µg per adult for (S)-carvone > cuminaldehyde > A. graveolens > C. cyminum > P. crispum. All EOs/standard compounds reduced significantly the percentage of insects attracted to maize grains (65–80%) in the two-choice repellence test, whereas in the area preference bioassay RD50 varied from 1.4 to 45.2 µg cm−2, with cuminaldehyde, (S)-carvone and estragole being strongly repellents. Petroselinum crispum EO and cuminaldehyde affected the nutritional parameters relative growth rate, efficiency conversion index of ingested food and antifeeding effect, displaying antinutritional effects toward S. zeamais. In addition, P. crispum and C. cyminum EOs, as well as cuminaldehyde, showed the highest acetylcholinesterase inhibitory activity in vitro (IC50 = 185, 235 and 214.5 µg mL−1, respectively). EOs/standard compounds exhibited acute toxicity, and some treatments showed antinutritional effects towards S. zeamais. Therefore, the tested plant products might be good candidates to be considered to prevent damages caused by this pest.
