“…PSMO reduction, caused by the action of the synergist, impacts insecticide efficacy. PSMO reduction decreases the activity of chlorpyrifos, due to a phenomenon known as bioactivation which has been described for organophosphates (Feyereisen, 1999) and detected in field populations with a high level of PSMO activity (Dunley & Welter, 2000; Bosch et al ., 2018). The complex chemical reactions of PSMO can lead to both insecticide bioactivation and detoxification (Levi et al ., 1988), as it was seen in honeybees (Iwasa et al ., 2004).…”

“…Therefore, to study the basal levels of enzymatic detoxification activities in different species, susceptible strains reared for a long time in the laboratory, fed with the same artificial diet, can be very useful. In contrast, the use of field populations may imply the co-occurrence of different resistance mechanisms, complicating the interpretation of results (Soderlund & Bloomquist, 1990; Bosch et al ., 2018).…”

We examined the role of the most important metabolic enzyme families in the detoxification of neurotoxic insecticides on adult males and females from susceptible populations of Cydia pomonella (L.), Grapholita molesta (Busck), and Lobesia botrana (Denis & Schiffermüller). The interaction between the enzyme families – carboxylesterases (EST), glutathione-S-transferases (GST), and polysubstrate monooxygenases (PSMO) – with the insecticides – chlorpyrifos, λ-cyhalothrin, and thiacloprid – was studied. Insect mortality arising from the insecticides, with the application of enzyme inhibitors – S,S,S-tributyl phosphorotrithioate (DEF), diethyl maleate (DEM), and piperonyl butoxide (PBO) – was first determined. The inhibitors' influence on EST, GST, and PSMO activity was quantified. EST and PSMO (the phase-I enzymatic activities) were involved in the insecticide detoxification in the three species for both sexes, highlighting the role of EST, whereas GST (phase-II enzymes) was involved only in G. molesta insecticide detoxification. L. botrana exhibited, in general, the highest level of enzymatic activity, with a significantly higher EST activity compared with the other species. It was the only species with differences in the response between sexes, with higher GST and PSMO activity in females than in males, which can be explained as the lower susceptibility of the females to the tested insecticides. A positive correlation between PSMO activity and the thiacloprid LD50s in the different species-sex groups was observed explaining the species-specific differences in susceptibility to the product reported in a previous study.

“…Effective C. pomonella management mainly rely on chemical insecticides which has led to the development of insecticide resistance to most classes of insecticides (Sauphanor and Bouvier, 1995; Knight et al ., 2001; Reyes et al ., 2009; Rodriguez et al ., 2011; Voudouris et al ., 2011; Cichón et al ., 2013). Insecticide-resistance in codling moth field populations has been related mainly to increased enzymatic metabolization and target-site mutations (Reyes et al ., 2007, 2011; Voudouris et al ., 2011), including the sodium channel mutation (Reyes et al ., 2009; Franck et al ., 2012; Bosch et al ., 2018).…”

Pyrethroid insecticides were intensively used against Cydia pomonella in the Río Negro and Neuquén valley, main production area of pome fruits in Argentina. Therefore, the first objective was to evaluate lambda-cyhalothrin resistance levels in C. pomonella larvae from orchards in this area that are currently under pyrethroids treatments. The second objective was to evaluate the frequency of kdr mutation in C. pomonella across Argentina. High levels of resistance to lambda-cyhalothrin (resistance ratios > 30) were determined in all the populations evaluated. The L1014F (kdr) mutation was evaluated in 355 diapausing larvae collected in 12 orchards from San Juan to Santa Cruz provinces (1690 km away from each other). The highest frequency of kdr mutation was determined in larvae from the Río Negro and Neuquén valley (0.61), followed by those from Mendoza (0.36). The kdr allele was absent or present at very low frequencies in orchards subjected to low pyrethroid pressure. The frequency of detection of kdr mutation in C. pomonella from Argentina is related to the use of pyrethroids against this pest in different areas. Target-site insensitivity is, at least, one of the mechanisms involved in resistance to lambda-cyhalothrin in codling moth from the Río Negro and Neuquén valley.

“…The area of origin of C. pomonella is Eurasia and it is present in all main temperate fruit growing areas of the world [ 27 ]. Because C. pomonella larvae cause direct damage to fruit, control measures rely heavily on frequent insecticide sprays, which is against consumer preference and increases the risk of insecticide resistance [ 28 , 29 , 30 ]. To reduce the use of insecticides, several natural enemies have been evaluated for C. pomonella control, including pathogens, predators, and parasitoids [ 31 ].…”

Photo-selective nets (PSN) are used to manipulate the physiology of fruit crops. Besides their advantages to the crop, PSN potentially affect insect pests and their natural enemies. We aimed to assess the effects of these production systems on the searching behavior of the codling moth parasitoid, Mastrus ridens. We hypothesized that PSN and black standard nets (SN) affect the behavior of the parasitoid by delaying host localization and reducing parasitism. Laboratory experiments were carried out in closed cages under four treatment conditions: black SN, pearl PSN, red PSN, and no PSN as control (uncovered cages). Our results showed that the host localization of M. ridens was delayed under black SN and enhanced by pearl and red PSN. The PSN and the black SN did not affect the parasitism levels. In addition, the initial behavior of the parasitoid during the first 30 min of the bioassays was not affected by treatments. However, females spent most of the time walking around the arena, grooming, or resting, regardless of the color of the net. Parasitism was not affected under the PSN or the black SN; however, this must be verified in field conditions.
