“…The range of life parameters provided can ultimately be used in refined population models to better describe different scenarios for early-season population buildup, and bottle-neck survival. From a pest management perspective, this information can be further used to develop nutrient-based baits effective to attract ( Cai et al 2018 , Wong et al 2018 ) and reduce eggload in postoverwintering females, as it has been done with other pest tephritid flies ( Yee 2010 ).…”

Life history parameters are used to estimate population dynamics, mortality, and reproduction in insects relative to their surrounding environment. For Drosophila suzukii Matsumura (Diptera: Drosophilidae), an invasive agricultural pest, previous studies have estimated net reproductive rate (Ro), generation time (T), and intrinsic rate of population increase (rm). A main limitation is that these estimates were measured under relatively favorable settings, and do not reflect environmental conditions and physiological states encountered during dormancy periods. Therefore, this study investigated the impacts of 1) low temperatures and 2) dietary protein: carbohydrate ratios (P:C) on both survival and fecundity parameters of D. suzukii summer morphs (SM) and postoverwintering winter morphs (WM) over physiological age (degree-days, DD). In both morphs, reproductive rates were higher and lifespan was longer when flies were exposed to low protein (P:C 1:4) or carbohydrate-only diets (P:C 0:1) compared with high protein diets (P:C 1:1). WM had higher reproductive rates and longer generation times than SM on optimal 1:4 diet in all trialed temperatures, but at the lowest temperatures, SM had higher reproductive rates than WM in carbohydrate-only and high protein diets. This likely reflected delayed oogenesis and hindered reproduction after an overwintering period in WM receiving suboptimal diets. Oviposition for SM and WM receiving 1:4 diet commenced from 0 to 100 DD, and peaked between 400 and 500 DD, earlier than flies receiving 0:1 diet. These results suggest that dietary protein has a crucial role in early oogenesis, particularly for postoverwintering WM. The parameters developed here reflect the population dynamics of D. suzukii before and after the crop growing season, an essential time for population buildup, survival, and early and late host infestation.

“…However, even in low quantities, yeast stimulates feeding as demonstrated in a laboratory choice test measuring bait uptake: R. cerasi females consumed more of SY‐low + NAT‐low bait (0.05% dried brewer's yeast) than of NAT‐low of the same sugar content but without yeast (Vogt H, unpublished). Although yeast is known to increase egg production, we observed that higher yeast content neither had a negative effect on bait efficacy nor did it boost infestation in the control in our semi‐field trials in 2010 (Fig. ).…”

“…Thus, lower egg loads in bitter cherry ßies caught on traps (study 3) were unlikely caused 1) by less proteinaceous food on bitter cherry trees, 2) by bitter cherry ßies laying a greater proportion of their eggs before being captured than sweet cherry ßies, and 3) by traps attracting ßies with more eggs to sweet than bitter cherry trees. Comparisons of the results of studies 3 and 4 suggest that cherry ßies in nature have access to food most comparable to the 10:90 yeast extract:sucrose diet and not to the 20:80 diet, which maximizes egg loads in sweet cherry ßies (Yee 2010). When the 20:80 diet was fed to bitter and sweet cherry ßies, the difference in egg loads was smaller than when they were fed 0:100 Ð 10:90 diets, suggesting diets higher in amino acids are required to cause smaller bitter cherry ßies to develop nearly as many eggs as larger sweet cherry ßies ( Table 5).…”

The western cherry fruit fly, Rhagoletis indifferens Curran, infests introduced, domesticated sweet [Prunus avium (L.) L.], and tart cherries (Prunus cerasus L.) as well as native bitter cherry, Prunus emarginata (Douglas) Eaton. Bitter cherries are smaller than sweet and tart cherries and this could affect various life history traits of flies. The objectives of the current study were to determine 1) if body size and egg loads of flies infesting sweet, tart, and bitter cherries differ from one another; and 2) if any observed body size differences are genetically based or caused by the host fruit environment. Pupae and adults of both sexes reared from larval-infested sweet and tart cherries collected in Washington and Montana were larger than those reared from bitter cherries. In addition, flies of both sexes caught on traps in sweet and tart cherry trees were larger than those caught in bitter cherry trees and females trapped from sweet and tart cherry trees had 54.0-98.8% more eggs. The progeny of flies from naturally-infested sweet and bitter cherries reared for one generation in the laboratory on sweet cherry did not differ in size. The same also was true for progeny of sweet and bitter cherry flies reared in the field on bitter cherry. The results suggest that the larger body sizes of flies from sweet and tart cherries than bitter cherries in the field are caused by host fruit and not genetic factors.
