“…Given that energy production through mitochondrial oxidative phosphorylation is a ubiquitous process in the animal kingdom, menadione may have a broad-spectrum insecticidal activity similar to chlorfenapyr, a pyrrole insecticide [43,44]. Chlorfenapyr was effective as a slow-acting, non-repellent termiticide against multiple subterranean termite species, including C. formosanus, C. gestroi (Wasmann), R. flavipes, and R. hesperus Banks [45][46][47][48][49].…”

The Formosan subterranean termite, Coptotermes formosanus Shiraki, is a highly destructive pest and a cosmopolitan invasive species. Sustainable termite management methods have been improving with the search for novel insecticides that are effective, safe, and cost efficient. Menadione, also known as vitamin K3, is a synthetic analogue and biosynthetic precursor of vitamin K with low mammalian toxicity. Menadione has shown insecticidal activity in several insects, presumably due to interference with mitochondrial oxidative phosphorylation. However, little is known about its effectiveness against termites. In this study, we evaluated the toxicity and repellency of menadione in C. formosanus. Our results showed that menadione affected the survival and feeding activity of termites both in filter paper and substrate (sand) treatments, and menadione influenced termite tunneling activity in treated sand. In a no-choice assay, ≥90% mortality after seven days and minimal or no food consumption were recorded when sand was treated with menadione at 6 to 600 ppm. In a two-choice assay with a combination of treated and untreated sand, termites were deterred by menadione at 6 to 600 ppm and exhibited low mortality (≤30%) over seven days, while tunneling activity was prevented with 60 to 600 ppm of menadione treatment. Overall, our study demonstrated dose-dependent toxicity and repellency of menadione in C. formosanus. The potential use of menadione as an alternative termite control agent is discussed.

“…Chlorfenapyr is a potent insecticide used against a wide range of pests as a disruptor to the oxidative phosphorylation process and inhibits the (Adinosin triphosphate enzyme) ATP synthesis in the respiration process in the target pest (Hollingworth and Gadelhak 1998). Peterson et al (2013) used chlorfenapyr as a soil treatment against termites. The results found that chlorfenapyr was very effective as a soil treatment against termites.…”

Both hunting billbug, Sphenophorus venatus and white grub, Phyllophaga crinita are considered the most destructive pest for golf courses not only in Egypt but worldwide. This work is considered the first record of P. crinita in Egypt. So, many efforts were carried out to control these pests. In this work nanopesticides formulations were used against these pests; imidacloprid nanocapsule and chlorfenapyr nanocapsule under laboratory conditions. Three concentrations were used for each nanocapsule. Two stages for each pest were treated; the third and sixth instar larvae of S. venatus and the first and third instar larvae of P. crinita. The obtained results showed that the nanocapsule formulations of both imidacloprid and chlorfenapyr were very effective against S. venatus and P. crinita larvae. The LC50 of imidacloprid and chlorfenapyr nanocapsule against the sixth instar larvae of S. venatus were 10.3 and 11.8 ppm, respectively, and 8.8 and 9.1 ppm, respectively, against the third instar larvae. The corresponding results with the third and first instar larvae of P. crinita were 11.2 and 17.2 ppm, and 8.7 and 11.6 ppm, respectively. The results showed also imidacloprid nanocapsule was more effective than chlorfenapyr nanocapsule especially, with the first concentration; the percentages of mortality ranged between 91.7 to 96.7% with imidacloprid nanocapsule compared with 75 to 88.3% with chlorfenapyr nanocapsule. The obtained results found that the nanocapsule formulations were very promising in the control of S. venatus and P. crinita larvae. These formulations can be reduced soil contamination compared with the traditional formulations.

“…12,13 Chlorfenapyr binds strongly to soil particles and degrades slowly, and is emerging as a serious environmental pollutant. 14 Residues of chlorfenapyr have been detected in water samples and lake sediments. 15,16 There is growing interest to develop methods for reducing the usage of chlorfenapyr and remediation of chlorfenapyr polluted soil and water.…”
