“…(3) pheromone combined with insecticide (lure-andkill); and (4) mating disruption by permeating an area with pheromone (Ujváry, 2001). Additional approaches, which aim to manipulate insect pest populations include: manipulating interactions between insect pheromones and other semiochemicals; manipulating populations of pests, their predators and the plants on which they feed; and using pheromones and other semiochemicals to repel pests or attract natural enemies (Smart et al, 2014).…”

Sand flies are an ancient group of Diptera estimated to contain 1000 species. Approximately 70 of these transmit pathogens (viruses, bacteria and protists), which cause human and animal diseases. The most important are the Leishmania parasites, transmitted to humans and animals, during blood feeding by female sand flies, and which cause diseases that can be fatal or disfiguring. Sand flies are known to use volatile chemicals produced by plants to locate sugar meals, host odours to locate a blood meal, and chemicals from decaying vegetation and other sources to identify oviposition sites. In a limited number of cases, male sand flies also produce volatile chemicals (sex/aggregation pheromones) that are attractive to females and other males. The presence of sex/aggregation pheromones is well documented in Lutzomyia longipalpis sensu lato, the South American vector of Leishmania infantum, in which they were first identified 40 years ago. During this time, a range of behavioural and chemical methodologies have been applied to their study in the laboratory and the field. The presence of sex/aggregation pheromones has also been suggested in a small number of other New and Old-World vectors, but the evidence is incomplete, as it is either solely chemical, i.e. without supporting behavioural evidence or behavioural evidence is available, but there is no supporting chemical evidence. Within the Lu. longipalpis s.l. species complex, the sex/aggregation pheromones provide a taxonomic guide to the members of the complex. There are four different known chemical types (five members of the complex), and one of these, the most geographically widespread, has been synthesised in bulk quantity. The synthetic pheromone, co-located with insecticide, has been shown to significantly reduce numbers of sand flies, and leishmania infection in dogs, the reservoir of human infection, and could significantly impact the number of human cases.

Three acaricides (azadirachtin, abamectin, and hexythiazox) were used, the effects on development parameters of Taşköprü garlic, Allium sativum L. (Asparagales: Amaryllidaceae) as seed treatment. This research was done in 2013-2014 on one hectare of garlic at Alatarla, Kastamonu, Turkey. Each acaricide and the untreated control were designated as four replicates on 16 plots. The effects of these acaricides on the germination rate and head weight of Taşköprü garlic were evaluated through regular sampling. Azadirachtin positively affected germination rate of Taşköprü garlic, while the other two acaracides had no effects on germination rate. None of the acaricides affected garlic head weights or head development. This is the first field study to evaluate acaracides that may also affect plant development.

“…Rotenone is a non-systemic insecticide to remove aphids, maggots, bagworms, codling moths, Japanese beetles, leaf hoppers, flea beetles and vegetable weevils for fruit and vegetable (Ray, 1991;Tyler et al, 1976;Ujváry, 2001). In household, it is used to control insects in the garden and on pets, as well as eliminate fish for water management.…”

The genus Derris belonging to Fabaceae family are distributed along the equatorial zone in Africa and Asia. In Thailand, 16 species of Derris species can be found throughout the country. Derris elliptica (Hanglai-Dang), is well-known among fishermen and gardeners as fish poison and insecticide, especially the stem and root which contain isoflavonoid compound named rotenone. This study established the pharmacognostic specification of Derris elliptica dried stem crude drug and developed the quantitative analysis of rotenone content in D. elliptica stem using TLC-densitometry and image analysis. The physico-chemical parameters of D. elliptica stem included total ash, acid-insoluble ash, loss on drying and water contents that should not be more than 7, 1, 5 and 8 g/ 100g crude drug, respectively. The ethanol and water extractive values should not be less than 4 and 11 g/ 100 g crude drug, respectively. Microscopic characteristics (transverse section and powder) of D.elliptica stem were illustrated by hand drawing. Rotenone contents obtained from both quantitative TLC were 0.2870 ± 0.1242 and 0.2844 ±0.1209 g/100 g crude drug, respectively which was not statistically significantly different (P > 0.05). In vitro biological activities of the stem ethanolic extract and rotenone revealed the antioxidant, α-glucosidase inhibitory properties and brine shrimp toxicity. MTT assay revealed that the ethanolic extract and rotenone were marginal cytotoxic (LC50 > 20 µg/ml) against the cancer cells (MAD-231, HepG2, HT-29, CaCo-2). Microscopic leaf characteristics including leaf constant numbers of 8 Derris ( D. amonea, D. malaccensis, D. elliptica, D. reticulate, D. trifoliate, D. indica, D. solorioides ) were shown that stomatal number, stomata index, palisade ratio, epidermal cell area, trichome number could be used as the identification key for selected 8 species. DNA fingerprinting using ISSR 11, 12, 14, 17 and 35 as primers produced a total of distinct and reproducible 256 bands. The genetic relationship among selected Derris species presented the similarity index between 0.11 to 0.43. The information from this research can be applied for identification of D. elliptica stems in Thailand as well as providing the information of pharmacogenetic specification, including rotenone content in and in vitro biological properties of D. elliptica stem.
