“…The identification of an attractive lure for C. nenuphar by Piñero and Prokopy [16] led to the development of an effective monitoring tool for this pest by Prokopy et al [13,14]. By establishing a few odor-baited trees on perimeter rows of apple orchards, apple growers can monitor C. nenuphar oviposition activity accurately and inexpensively [6]. The attract-and-kill strategy developed by Leskey et al [8,27] represented a new reduced input strategy for managing C. nenuphar in apple orchards, based on the application of insecticides to a few perimeter-row odor-baited trap trees, rather than the entire perimeter row.…”

“…Damage to fruit by C. nenuphar is initiated as soon as fruit reach a diameter of 6-7 mm, and results from feeding and oviposition scars produced by adult females and from burrows made by the larvae [3]. Currently, to provide commercially acceptable levels of C. nenuphar control, many fruit growers in the northeast continue to apply up to three whole-orchard broad-spectrum insecticide sprays [4][5][6]. This situation makes C. nenuphar a major obstacle to ecological and sustainable pest management programs in tree fruit orchards [2,7,8].…”

“…For many apple growers in MA and other New England states, ≤1% is an economically acceptable level of whole-block fruit injury by C. nenuphar [6,8]. To successfully manage C. nenuphar in a reduced-spray environment that would result in tolerable injury levels, then it is imperative that alternative management strategies consider the ecology and behavior of the target pest, as well as biological control options that may be available.…”

Efforts to reduce insecticide inputs against plum curculio, Conotrachelus nenuphar, a key pest of apples in eastern North America, include perimeter-row insecticide sprays applied after the whole-orchard petal fall spray to manage dispersing adults and, more recently, insecticide sprays confined to odor-baited trap trees. Entomopathogenic nematodes (EPNs) are virulent to ground-dwelling stages of C. nenuphar, and may be applied to the ground underneath trap-tree canopies. Here, we (1) compared the efficacy of the odor-baited trap tree approach with grower-prescribed (=grower standard) sprays to manage C. nenuphar populations over a six-year period in seven commercial apple orchards in New England; and (2) assessed the performance of the EPN Steinernema riobrave at suppressing ground-dwelling stages of C. nenuphar. In addition, the performance of S. riobrave was compared against that of S. carpocapsae and S. feltiae in one year. Across the six years, percent fruit injury on trap tree plots averaged 11.3% on odor-baited trap trees and 1.4% on unbaited trees in grower standard plots, highlighting the ability of trap trees to aggregate C. nenuphar activity and subsequent injury. Mean percentage injury on fruit sampled from interior trees, the strongest measure of treatment performance, in trap tree plots did not differ significantly from that recorded on interior trees in grower standard spray plots (0.95 vs. 0.68%, respectively). Steinernema riobrave consistently reduced C. nenuphar populations as indicated by the significantly lower number of adult C. nenuphar that emerged from the soil, when compared to water control. Steinernema carpocapsae and S. riobrave performed similarly well, and both EPN species outperformed S. feltiae. Our combined findings indicate that an IPM approach that targets multiple life stages of C. nenuphar has the potential to manage this pest more sustainably in a reduced-spray environment.

“…Among the factors identified as contributing to unpredictable captures by pyramidal traps, 12,19 the presence of pesticide residues has been overlooked. Furthermore, reduced input strategies such as perimeter row sprays 13,14 and baited trap trees used for both monitoring 20 and for management 21 were originally designed using organophosphates. 21 In order to understand how incidental contact with newer insecticides and cornerstone materials such as organophophates, as well as commonly encountered fungicides, influences trapbased monitoring procedures and reduced input management strategies, plum curculio was utilized as a model organism for mobility bioassays conducted in the laboratory.…”

BACKGROUNDAn evaluation was made of the effects of seven neurotoxic insecticides (esfenvalerate, indoxacarb, clothianidin, thiacloprid, azinphosmethyl, phosmet and imidacloprid), one insect growth regulator (novaluron) and two fungicides (myclobutanin and mancozeb), with water as the control, on the horizontal mobility of plum curculios exposed to dried pesticide residues. Mobility was recorded over a 2 h period using ethological tracking software. Mortality was recorded immediately after horizontal mobility experiments and 24 h later.RESULTSEsfenvalerate had the greatest impact on mobility. Immediately after exposure to this compound, plum curculios moved significantly greater distances and for a significantly longer period of time compared with all other compounds. After 24 h, esfenvalerate also led to high mortality rates (>86.0%). Exposure to azinphosmethyl and phosmet also led to high rates of mortality, although the impact on mobility was less pronounced. Exposure to indoxacarb, thiacloprid, imidacloprid, novaluron, myclobutanin and mancozeb had no impact on mobility and resulted in little to no mortality. Clothianidin affected mobility after a 2 h exposure period, and high mortality (60%) was recorded after 24 h.CONCLUSIONSThe results indicate that, in the context of a treated orchard, plum curculios exposed to dried pesticide residues may be capable of foraging before succumbing to toxicant exposure, while exposure to pesticides such as esfenvalerate may rapidly incapacitate adult plum curculios.

“…These compounds may be used for monitoring pest populations or as a control method (e.g., mass trapping) (Wyatt 2014). There are some successful examples of the use of semiochemicals for monitoring, mass trapping, and mating disruption of weevil species (Dickerson et al 1987;Chinchilla et al 1996;Downham et al 2001;Oehlschlager et al 2002;Piñero et al 2011).…”
