“…O manejo do pomar envolve o controle de doenças e pragas, e dentre as pragas que mais ocorrem em pessegueiros, nectarinas e ameixas é a Grapholita molesta (BUSCK, 1916) (Lepidoptera: Tortricidae). Os danos são ocasionados pela lagarta, a qual ataca ponteiros de ramos e frutos (GALLO et al, 2002), proporcionando também indiretamente a entrada de outros patógenos como a podridão parda, causada pelo fungo Monilinia fruticola (BOTTON et al, 2001;BERNARDI;LAZZARI, ANDREAZZA, 2017).…”

“…A forma mais utilizada de controle de G. molesta é o químico com uso de inseticidas sistêmicos neurotóxicos, porém o uso de cultivares resistentes ou com grau de resistência moderado é uma alternativa viável e ambientalmente mais segura. As cultivares resistentes sofrem menos danos em condições de ataque de G. molesta e podem interferir no ciclo de vida do inseto, possibilitando mudanças na forma de manejo da fruta de caroço no Sul do Brasil (BIASI et al, 2004;BERNARDI et al, 2017).…”

O Brasil é um dos principais produtores de frutas no mundo. Aproximadamente 70% da produção se encontra na região Sul e Sudeste. O manejo do pomar envolve o controle de doenças e pragas, e dentre as pragas que mais ocorrem em frutíferas de caroço é a Grapholita molesta. Os danos são ocasionados pela lagarta, a qual ataca ponteiros de ramos e frutos. Objetiva-se com esse trabalho avaliar diferentes cultivares de frutíferas de caroço ao ataque da espécie Grapholita molesta (Busck) (Lepidoptera: Tortricide), em um pomar jovem, em busca de cultivares mais tolerantes a essa espécie. Para este estudo foram analisadas sete cvs Chimarrita, Eragil, Seleção 01/08, Charme, Ouro, Della Nona e FLA 8-1 para pêssego. Para ameixeira (Prunus domestica) foram utilizadas cinco tipos de cvs., sendo elas Amarelinha, Seleção 02/08, Irati, Reubenel e Fortuna. Para nectarina (Prunus persica var. nucipersica) foram avaliadas três cvs. Bruna, FLA 9-15N e Sunripe. O delineamento foi em blocos ao acaso com 10 repetições por tratamento. Os dados foram submetidos à análise de variância, sendo as médias comparadas pelo teste de Tukey (P > 0,05). O estudo mostrou que a cv. Charme (46,0%) foi a mais resistente ao ataque de G. molesta em pessegueiro. Já para ameixeira as cvs mais resistentes são Reubennel com 54% e Fortune com 48% de danos nos ponteiros. Já para nectarina as cvs. mais resistentes são Sunripe (62%) e Fla 9-15N (61%). Os resultados demonstram uma maior intensidade de danos em variedades menos vigorosas.

Early‐life food stress hits females harder than males in insects: A meta‐analysis of sex differences in environmental sensitivity

Fitness consequences of early‐life environmental conditions are often sex‐specific, but corresponding evidence for invertebrates remains inconclusive. Here, we use meta‐analysis to evaluate sex‐specific sensitivity to larval nutritional conditions in insects. Using literature‐derived data for 85 species with broad phylogenetic and ecological coverage, we show that females are generally more sensitive to food stress than males. Stressful nutritional conditions during larval development typically lead to female‐biased mortality and thus increasingly male‐biased sex ratios of emerging adults. We further demonstrate that the general trend of higher sensitivity to food stress in females can primarily be attributed to their typically larger body size in insects and hence higher energy needs during development. By contrast, there is no consistent evidence of sex‐biased sensitivity in sexually size‐monomorphic species. Drawing conclusions regarding sex‐biased sensitivity in species with male‐biased size dimorphism remains to wait for the accumulation of relevant data. Our results suggest that environmental conditions leading to elevated juvenile mortality may potentially affect the performance of insect populations further by reducing the proportion of females among individuals reaching reproductive age. Accounting for sex‐biased mortality is therefore essential to understanding the dynamics and demography of insect populations, not least importantly in the context of ongoing insect declines.

Cosmopolitan agricultural herbivorous pests are provided with a wide range of potential hosts. Therefore, they have high carrying capacity, and can cause extremely severe damage in agroecosystems. Understanding the ecological mechanisms of their population dynamics, especially as they relate to large-scale meteorological variations and geographical landscape influences, can help us to reveal how they became such important pests. The oriental fruit moth, Grapholita molesta, is a typical example of a significant pest distributed on a large scale, which is capable of damaging fruit trees of economic value such as peach, apple, pear, etc. This pest not only occurs in China, but exists on all continents except Antarctica. In order to prevent major pests and diseases, a system of plant protection has been established gradually in peach orchards within the Modern Agro-industry Technology Research System in China (CARS) since 2009. In the system, we collected the monitoring data of G. molesta by using pheromone traps at 17 experimental stations, and then used the corresponding climate data (temperature and precipitation) to explore the link between climate factors using mixed models. The results show that both monthly mean temperature and precipitation had a significant positive correlation with the occurrence of G. molesta. Therefore, global warming with higher levels of precipitation may favor G. molesta, allowing it to outperform other potential pests at the population level in peach orchards, on a large scale.
