Protein baits target adult fruit flies, which need protein for reproductive maturation. A proper understanding of the factors influencing fruit fly responses to protein is required to optimise control outcomes. In this study, responses to protein bait by three fruit fly species, <ce:italic>Ceratitis capitata</ce:italic> (Wiedemann), <ce:italic>C</ce:italic>. <ce:italic>cosyra</ce:italic> (Walker), and <ce:italic>Bactrocera dorsalis</ce:italic> (Hendel), were investigated. This was done in two field cages erected over lemon trees within an orchard. The response of each species to protein bait presented as a station and positioned at different heights within the tree canopy was evaluated. For each species, effects of fly age, sex, and nutritional status were evaluated under conditions of varying temperature and relative humidity. The highest response occurred when protein baits were placed in the middle to upper tree canopy. Species, nutritional status, sex and age also affected protein foraging. <ce:italic>Ceratitis capitata</ce:italic> responded more to bait compared to <ce:italic>B. dorsalis</ce:italic> and <ce:italic>C. cosyra</ce:italic>. The lowest response to protein bait was by one-day-old protein fed flies, while 10-day-old protein-deprived flies were most responsive. Protein deprived females were more attracted to protein than males fed the same diet. Flies responded to bait when temperatures were between 20 and 30°C. Based on the results, the success of protein baits in controlling fruit flies in a tree canopy is height dependent and can be lower in areas with alternative protein sources.","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"109 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144621889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soybean varieties are classified based on their morphological growth habit, which can be determinate or indeterminate. In varieties with a determinate growth habit, the onset of reproductive growth results in the termination of vegetative growth, while soybean with indeterminate growth habits continue vegetative growth even after entering their reproductive stages. Management recommendations for <ce:italic>H. zea</ce:italic> in the southeastern US were developed from soybean varieties with determinate growth habits. The objective of this research was to understand the compensatory ability of these growth habits to <ce:italic>H. zea</ce:italic> feeding. We hypothesized that soybean with an indeterminate growth habit might have a greater ability to compensate yield components following <ce:italic>H. zea</ce:italic> feeding compared to determinate growth habits, as indeterminates typically flower for a longer time. We designed a field experiment comparing a single determinate and indeterminate soybean variety within the same relative maturity.

Yield components were collected to detect differences between growth habits. We found that indeterminate varieties showed greater compensation by adjusting pod type and seed weight, particularly under partial tissue removal. Indeterminate plants produced more one- and four-seeded pods, while determinate plants increased three-seeded pods. Total tissue removal reduced yield components, but moderate damage allowed for compensation. Differences may be driven by environment and should be tested across more varieties.","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"38 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144621891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The logarithms of EC₅₀ values fitted the normal distribution and with a relatively flat peak. Light microscopic observations revealed that difenoconazole treatment resulted in shorter, more contorted hyphal of <em>S. sclerotiorum</em> with increased offshoots at the tips.

Further analyses revealed that difenoconazole induced reactive oxygen species accumulation, decreased cell membrane permeability, reduced oxalic acid content, pectinases activity, and decreased ergosterol content (<em>P</em> &lt; 0.05). No correlation was found between the sensitivity of <em>S. sclerotiorum</em> isolates to difenoconazole and three DMI fungicides.

Based on a grower perception survey conducted in ten major apple-growing districts, we assessed the reported incidence of GAA, the management practices adopted by growers, and the perceived economic losses incurred. We found that the high incidence of GAA is widespread in all apple growing districts and on all the major commercial varieties under cultivation (Delicious group) including newly introduced varieties in the Gala group. Up to four additional insecticide sprays are needed for the management of GAA. The type of insecticides sprayed is dominated by the old chemistry insecticides like dimethoate, chlorpyriphos and cypermethrin. Higher number of sprays is needed if these insecticides are included in the spray regimes, and these insecticides are responsible for control failures. The cost of insecticide treatments can lead to 13.13 % increase in cost of cultivation in case of traditional orchards, and up to 18.58 % in case of high-density orchards, and 4.37 %–11.67 % increase in cost of post-harvest operations owing to incidence of sooty mold on harvested fruit. It is concluded that GAA has a significant economic impact on the apple production system in India. The probability of insecticide resistance development seems to be the major reason for GAA outbreaks in the recent years.
