“…In similar control failure cases in the United States, development of resistance to azinphosmethyl was predicted (Riedl et al, 1985), and later confirmed (Croft and Riedl, 1992;Knight et al, 1994;Chapman andBarrett, 1997: Welter et al, 1991;Varela et al, 1993). In the last 20 years resistance and cross-resistance of the codling moth to various insecticides has been recorded (Moffitt et al, 1988;Welter et al, 1991;Bush et al, 1993a;Sauphanor and Bouvier, 1995;Dunley and Welter, 2000).…”

Resistance of the codling moth Cydia pomonella (L.) (Lep., Tortricidae) to the organophosphorus compound (OP) azinphosmethyl was observed in apple orchards in Israel. The level of resistance varied with the pest control strategy. Compared with a sensitive laboratory population, the resistance level was highest in insects from the preventative pest control strategy, intermediate in integrated pest management (IPM) orchards, and relatively low in the organic orchards. The level of azinphosmethyl resistance in larvae (but not in adults) exposed for 17 generations in the laboratory to a pesticide-free diet was reduced by 50%. Codling moth larvae resistant to azinphosmethyl were also resistant to various insect growth regulators (IGRs). The IGRs include three chitin synthesis inhibitors (diflubenzuron, novaluron and teflubenzuron), two juvenile hormone mimics (pyriproxyfen and fenoxycarb) and one ecdysone agonist (methoxyfenozide). Codling moth resistant to azinphosmethyl was tolerant to methoxyfenozide and novaluron without previous history of application in apple orchards, indicating the possibility of cross-resistance. According to this study, managing resistance programs in apple orchards should be based on IPM principles with minimum use of conventional neuroactive pesticides.

“…Chemical control of this pest has many drawbacks including insecticide resistance, side effects on natural enemies and beneficial species and initiate secondary mite problems (Theiling and Croft 1988;Desneux et al 2007, Welter et al 1991Varela et al 1993;Knight et al 1994;Rothschild 1982). In addition, the high insecticide residues on fruits due to the intensive insecticide spray program caused difficulties in exporting the country's surplus of this crop (Al-Motny 1997).…”

The sensitivity of the Mediterranean flour moth, Ephestia kuehniella, eggs in different stages of development to gamma irradiation was studied and the acceptability of irradiated eggs by Trichogramma cacoeciae females was examined. Eggs ranging in age from 1-24 to 49-72 h were exposed, at 24 h intervals, to gamma radiation dosages ranging from 25 to 400 Gy and effects of gamma radiation on egg hatch and adult emergence was investigated. In addition, the developmental rate of immature stages (larvae and pupae), resulting from irradiated eggs, to the adult stage was examined and the acceptance of irradiated eggs to T. cacoeciae females was evaluated. Results showed that the radio-sensitivity of E. kuehniella eggs decreased with increasing age. Egg hatch in 1-24-h-old eggs was significantly affected at 25 Gy dose and at 75 Gy dose, no egg hatch was observed. When irradiating 25-48-h-old eggs, however, egg hatch was less than 5% at 100 Gy dose, and eggs 49-72-h-old were more resistant; 50 Gy had no significant effect on egg hatch and 300 Gy did not completely prevent it. Irradiation also negatively affected survival to the adult stage. When 25-48-h-old eggs were irradiated, survival to the adult stage was completely prevented at 75 Gy dose and no survival was observed beyond 100 Gy dose in 49-72-h-old eggs. In addition, the rate of development of immature stages resulting from irradiated eggs was negatively affected. While more than 97% of control moths emerged within 30 days, this ratio decreased to 53 and 69% in 1-24 and 25-48-h-old eggs exposed to 25 Gy dose. Furthermore, irradiation positively affected the degree of acceptance of eggs to parasitization; irradiated eggs (B49-h-old) were more acceptable to T. cacoeciae than cold-treated ones.

“…In the codling moth, Cydia pomonella L., cross-resistances to different classes of insecticides have been related to enhanced detoxification (Sauphanor et al, 1997;Bouvier et al, 2002), whereas a kdr mutation through leucine to phenylalanine replacement at position 1014 of the voltagedependent sodium channel gene has been identified in pyrethroid resistant populations (Brun-Barale et al, 2005). Organophosphorous (OP) insecticides are the most intensively used against C. pomonella worldwide and resistances to these compounds have frequently been recorded in this species (Welter et al, 1991;Bush et al, 1993;Knight et al, 1994;Sauphanor et al, 1998;Dunley and Welter, 2000;Reuveny and Cohen, 2004). OPs irreversibly inhibit acetylcholinesterase (AChE, EC 3.1.1.7) which is a key enzyme catalysing the hydrolysis of the neurotransmitter acetylcholine in the nervous system, thereby ending transmission of nerve impulses at cholinergic synapses.…”
