the mating disruption technique has been widely used for the control of several lepidopteran pests. in the present study, we assessed the efficiency of two formulations of splat neo, a wax emulsion containing e-11-hexadecenol, with and without the insecticide cypermethrin, in affecting mating disruption of neoleucinodes elegantalis (guenée). we also determined the best phenological age or stage...

This study identified statistically significant, and practically important, seasonal pheromone trap response dynamics of Euschistus conspersus (Uhler) in processing tomatoes in 12 fields over 5 years in California, USA. Commercial fields were monitored weekly using traps baited with Euschistus spp. pheromone and direct canopy shake samples. Regression analysis determined no significant relation...

A significant portion of crop production in the tropics occurs at subsistence level with high vulnerability to climate change. Process-based simulation models are effective tools predict environmental impacts, including change effects, and make management decisions on production. The principal objective this work was develop crop-specific phenology, canopy growth, yield performance maize, mungb...

The BBCH (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie) scale is a system that helps producers monitor phenology by employing uniform methodology across different locations. This study aimed to evaluate the effect of scion×rootstock combinations on tomato yield and accumulated degree days for each phenological stage. A randomized block design with four repetitions treatmen...

Quality is a key trait in plant breeding, especially for fruit and vegetables. Quality involves several polygenic components, often influenced by environmental conditions with variable levels of genotype × environment interaction that must be considered in breeding strategies aiming to improve quality. In order to assess the impact of water deficit and salinity on tomato fruit quality, we evalu...

Solanum lycopersicum (tomato) is one of the most common agricultural crops in world. Its production Mexico and world depends on application nitrogenous fertilizer such as NH4NO3, which, used rationally or reduced doses according to needs plant, avoids environmental pollution addition emission N2O (oxide nitrous), greenhouse gas. One option reduce optimize apply Azotobacter vinelandii Xanthobact...

1. Neotropical migrant birds show a clear preference for stopover habitats with ample food supplies; yet, the proximate cues underlying these decisions remain unclear. 2. For insectivorous migrants, cues associated with vegetative phenology (e.g. flowering, leaf flush, and leaf loss) may reliably predict the availability of herbivorous arthropods. Here we examined whether migrants use the pheno...

Climate-induced crop yields model projections are constrained by the accuracy of the phenology simulation in crop models. Here, we use phenology observations from 775 trials with 19 rice cultivars in 5 Asian countries to compare the performance of four rice phenology models (growing-degree-day (GDD), exponential, beta and bilinear models) when applied to warmer climates. For a given cultivar, t...

Nowadays, increments in tomato yield seem to have reached a plateau. Tomato genebank collections been recognized as novel source for increments. The use of the diversity Latin America improved varieties is limited by knowledge gap regarding field-grown tomatoes. As has complex, unresolved trade-offs, agromorphological traits become useful further improvement. In this study, development successi...
