“…Within the UK the active ingredients currently used against B. tabaci are imidacloprid, spiromesifen and th iaclopr id. However, th e continued development of whitefly populations resistant to chemical insecticides (Ahmad et al, 2002;Cahill et al, 1994;Cannon et al, 2005), indicates that further chemicals and or biological agents must be investigated for their efficacy against B. tabaci (De Barro, 1995;Dennehy and Williams, 1997;Osborne and Landa, 1992;Prabhaker et al, 1985). To contin ue pr ovidin g h orticultur al consultan ts an d protected or n amen tal an d horticultural growers with sufficient information on which to base commercially viable control decisions, data on the efficacy of a wider range of insecticides for the control of all lifestages of B. tabaci (eggs, larvae and adults) is urgently required.…”

ABSTRACT:The screening of potential chemicals for control of Bemisia tabaci on poinsettia (Euphorbia pulcherrima c.v. Lilo Pink) plants using a leaf dipping technique was investigated. All relevant B. tabaci lifestages (eggs, larvae and adults) were investigated. In leaf dipping tests, Certis spraying oil was the only compound to show potential to be used as a control agent against B. tabaci eggs, with 81% obtained mortality. Oberon resulted in no mortality of B. tabaci eggs in the reported experiments. Leaf dipping against second instar and adult B. tabaci proved more effective for all chemical products. Dipping techniques using Majestik, Certis spraying oil and Agri-50 E all resulted in high second instar larval mortality (93, 87 and 85.5 %, respectively). Certis spraying oil again resulted in a high efficacy against adult B. tabaci with 100 % mortality obtained. The potential of the various chemicals to be incorporated into integrated pest management strategies for the control of B. tabaci is discussed.

“…Microbial pest control agents (MPCAs) are receiving renewed attention from private industry for potential commercialization, particularly in cases where the pest is not effectively controlled by chemical pesticides (Osborne & Landa 1992) or where the use of chemical pesticides poses a significant risk to either human health or the environment. These factors, plus public sentiment which favors limiting the use of chemical pesticides, have created a promising market for such biological products.…”

A short-term (48 h ) chemical toxlcity test using larvae of the coot clam A4ulinia lateralis was modified to evaluate potential toxlcity and pathogenicity of microblal pest control agents. M. lateralls larvae, at the straight-hinged stage of developn~ent, were exposed to varlous microbial pest control agents including a mosquito larvac~de. Bacillus thur~ngiensis var israelensis (Bti); a mol1usc1-cidal strain of Bacillus alvei; a viral pathogen of the gypsy moth Lymantria dispar nuclear polyhedrosis virus (LdNPV); and a broad host-range fungal insect pathogen, Metarhizium anisopliae. Mortalities significantly h~g h e r than heat-killed controls were obtained w~t h Bti at a 10-4 dilution of a colnlnei-cial preparatlon, and w~t h LdNPV at an occlus~on body d e n s~t y of 1 X 10%1-' Sodlum dodecyl sulfate (SDS) and the ivater-soluble fraction of No. 2 fuel 011 ( W S r ) were also tested to provide a measure of comparison, sensitlv~ty and precision. SDS, toxic at an LC,, of 6.3 m g 1-', had a mean coefficient of variation of 23'X). The clam larval tox~city test was very sensitive to WSF,,,,, exposures resulted In an LC.,,, of <10% V/\! Because of its preclslon, sensitivity and simplicity, the M. lateralis larval test has the potential to be useful for assessing adverse effects that microblal pest control agents may have on nontarget bivalves KEY WORDS: B~o l o g~c a l control Nontarget effects .

“…According to some research results, 250 plant species have been identified as hosts for Glasshouse whitefly worldwide, and vegetables in particular (Osborne & Landa, 1992). The Glasshouse whitefly is a significant pest in economic terms with regard to glasshouse crops, due to the fact that this pest causes both direct and indirect damage, such as damaging leaves with honeydew, feeding on plant sap, and transmitting some plant viruses.…”

Glasshouse whitefly Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae) is one of the most economically important pests in terms of its damage to vegetable crops in glasshouse condition. Chemical control is still applied against this pest, but resistance has prevented the use of chemical control methods. In addition chemical pesticides pollute the environment. Biological control, therefore, is one of the viable alternative methods being use in the control of Glasshouse whitefly. The aim of this present study is to use of biological control against Glasshouse whitefly. The effectiveness of Encarsia formosa Gahan (Hymenoptera: Aphelinidae) was observed between three different varieties of the tomato and cucumber (Moneymaker (tomato), Alicante (tomato) and Telegraph Improved (cucumber)) for this study The results obtained from present study indicated that the percentage of parasitism was 67% for Moneymaker, 67% for Alicante, and 62% for Telegraph Improved. While there was no significant difference in the percentage of parasitism, there was only a difference in the number of whitefly eggs laid between in variety of Alicante ((tomato) and Telegraph Improved (cucumber) in this study. According to the results, the biological control using E. formosa against Glasshouse whitefly can be used successfully on varieties of Moneymaker (tomato), Alicante (tomato), and Telegraph Improved (cucumber) for the control of Glasshouse whitefly in glasshouses.
