  • Activity and Biological Effects of Neem Products Against Arthropods of Medical and Veterinary Importance
    Journal of the American Mosquito Control Association' 15(2):133-152, 1999 Copyright O 1999 by the American Mosquito Control Association, Inc. ACTIVITY AND BIOLOGICAL EFFECTS OF NEEM PRODUCTS AGAINST ARTHROPODS OF MEDICAL AND VETERINARY IMPORTANCE MIR S. MULLA ENN TIANYUN SU Depdrtment of Entomobgy, University of Califomia, Riverside, CA 92521-O314 ABSTRACT. Botanical insecticides are relatively safe and degradable, and are readily available sources of biopesticides. The most prominent phytochemical pesticides in recent years are those derived from neem trees, which have been studiedlxtensively in the fields of entomology and phytochemistry, and have uses for medicinal and cosmetic purposes. The neem products have been obtained from several species of neem trees in the family Meliaceae. Sii spicies in this family have been the subject of botanical pesticide research. They are ATadirachta indica A. Jrtss, Azadirachta excelsa Jack, Azadirachta siamens Valeton, Melia azedarach L., Melia toosendan Sieb. and Z1cc., and Melia volkensii Giirke. The Meliaceae, especially A. indica (Indian neem tree), contains at least 35 biologically active principles. Azadirachtin is the predominant insecticidal active ingredient in the seed, leaves, and other parts of the neem tree. Azadirachtin and other compounds in neem products exhibit various modes of action against insects such as antifeedancy, growth regulation, fecundity suppression and sterilization, oviposition repellency or attractancy, changes in biological fitness, and blocking development of vector-borne

    THE EFFECTS OF AZADIRACHTIN, METHOXYFENOZIDE, AND TEBUFENOZIDE ON THE YELLOW FEVER MOSQUITO, AEDES AEGYPTI by DANIEL JACK USRY (Under the Direction of Mark R. Brown) ABSTRACT Mosquito control is important to control the spread of pathogens which are transmitted by the bites of infected mosquitoes. To this end, research has focused on insecticides that are insect specific and have relatively low impact on the environment. Here I report on the plant botanical azadirachtin and the ecdysone agonists methoxyfenozide and tebufenozide. Overall, my results suggest that azadirachtin and tebufenozide are not suitable for use as insecticides, even though they cause mortality at high doses. Methoxyfenozide kills mosquitoes at high doses and reduces the number of eggs oviposited by females. Additionally, methoxyfenozide is able to stimulate egg production in non-bloodfed females. However, it is not able to cause eggs to develop all the way to oviposition.

The insecti­ cidal activity of certain B.t. kurstaki or B.t. tenebrionis A large number of physical and chemical pest control strains against the tobacco moth and cigarette beetle has methods have been developed up to now in order to already been sufficiently documented. Recent research ensure the effective protection of stored tobacco and has also looked at the possibility of using natural sub­ tobacco products. These methods include the use of fu­ stances, such as extracts from the neem tree (Azadirachta migants and insecticides, treatment of baled tobacco in indica), as storage protectants. Another very promising cold chambers, monitoring the extent of infestation with development is based on the autodissemination pheromone traps and, the most important preventive technique, whereby a modified pheromone trap in com­ measure of all, maintaining a strict programme to ensure bination with entomopathogenic viruses or fungi could hygienic storage conditions. To date, very little serious help to achieve a dramatic increase in mortality rates in consideration has been given to the practical use of bio­ stored tobacco pests. The chemical and biological proper­ logically based insecticides in storage pest control. Com­ ties of these bioinsecticides will be presented here and pared with synthetically-produced pesticides, however, their advantages and disadvantages as storage protectants they often have the advantage of being significantly less for tobacco discussed.

  • Chemical Class Rotations for Control of Bemisia Tabaci
    Research Article Received: 18 November 2013 Accepted article published: 24 January 2014 Published online in Wiley Online Library: (wileyonlinelibrary.com) DOI 10.1002/ps.3736 Chemical class rotations for control of Bemisia tabaci (Hemiptera: Aleyrodidae) on poinsettia and their effect on cryptic species population composition Cindy L McKenzie,a* Vivek Kumar,b Cristi L Palmer,c Ronald D Oettingd and Lance S Osborneb Abstract BACKGROUND: Bemisia tabaci, a polyphagous insect with over 900 host plants, is an effective vector of more than 100 plant viruses. Being highly fecund, B. tabaci has the potential to develop insecticide resistance rapidly, as demonstrated by reports of use failures with MEAM1 and MED cryptic species (commonly known as biotypes B and Q respectively). Insecticide resistance management is a key component of pest management practices. The research herein studied season-long rotational management programs on poinsettia and their impact on the ratio of MEAM1:MED cryptic species in the surviving treated populations. RESULTS: In all four experiments, only three of the treatments completely eliminated the adult or immature whiteflies, but all significantly reduced the populations. Out of 18 active ingredients tested, dinotefuran (applied as a soil drench) was the most efficacious against both MEAM1 and MED cryptic species compared with the other chemical or biorational insecticides evaluated. Reduced susceptibility of MED was reported against a variety of treatment regimes. CONCLUSION: Rotations can be used to manage MEAM1 and MED cryptic species and maintain a very low population level or completely eliminate Bemisia on poinsettia. It is imperative to continue to emphasize the importance of rotating among different modes of action in pest management programs in order to retain effective chemistries for as long as possible in the market place.
