Larvicidal activity of camphor and lavender oils against sheep blowfly, Lucilia sericata (Diptera: Calliphoridae)

Abstract

In this study, the essential oils of camphor and lavender were tested in vitro against the third instar larvae of Lucilia sericata for the first time, following dipping toxicity technique. The toxicity results revealed that L. sericata larvae were susceptible to the applied essential oils. Lavender oil was more effective than camphor in killing of L. sericata larvae. With 32 % concentration, the mortality percentages of larvae were 100 and 93.3 %, respectively. Light and scanning electron microscopic examinations were done to determine the cuticular changes of L. sericata larvae following exposure to the applied essential oils. Larvae showed cuticular swelling and distortion after oil treatment, but its level was greater with lavender oil. The current study suggested that an alternative, effective and natural product can be developed as larvicides against L. sericata using camphor and lavender oils.

Antioxidant Capacity of Four Edible Plant Extracts and Theirlarvicidal Effect on the Third Instar Cephalopinatitilator Larvae

“…Similar changes were observed in larvae of Chrysomyiaalbicepswhich exposed tospinosad, Zingiberofficinale (root) and Allium sativum (fruit) [51]. As well as Luciliasericata treated with camphor and lavender oils [52].…”

Potential of essential oils to prevent fly strike and their effects on the longevity of adultLucilia sericata

“…Formulations containing tea tree oil at 2.5% caused high mortality of both L2 and L3 of Lucilia cuprina in agar feeding assays (Callander and James 2012). Dipping assays of 3 rd instar L. sericata in 32% of lavender and camphor ( Cinnamomum camphora ) oil led to larval mortality of 100 and 93.3%, respectively, 24 h after exposure (Shalaby et al 2016). Larvae of L. sericata are also sensitive to other botanicals, including extracts of neem seed (El‐Khateeb et al 2003) and American wormseed ( Chenopodium ambrosiode ) (Morsy et al 1998).…”

Enzymatic Changes and Toxic Effect of Some Aromatic Plant Oils on The Cotton Leafworm, Spodoptera littoralis (Boisd.)

“…Lavender oil is useful for use in nervous system stimulants, hypnotics, sedatives, tranquilizers and stress repellents. In addition, it has useful dermatological uses in the treatment sunburn and skin rashes, as well as strong antiseptic and antibiotic effects (Shalaby et al, 2016). The genus Mentha belongs to the family Lamiaceae (Labiatae), and consists of about 25-30 species, most of which are found in temperate regions of Eurasia, Australia and South Africa (Lange and Croteau, 1999).…”
