Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled annual seasonal common pest, Helicoverpa zea (Boddie), based on three suitability zones throughout North America using four decades soil temperatures: southern range (able persist through winter),...
The jasmonate family of phytohormones plays central roles in plant development and stress acclimation. However, the regulatory modes their signaling circuitry remain largely unknown. Here we describe that cyclophilin 20-3 (CYP20-3), a binding protein (+)-12-oxo-phytodienoic acid (OPDA), crisscrosses responses with light-dependent redox reactions, which fine-tunes activity key enzymes plastid photosynthetic carbon assimilation sulfur pathways. Under stressed states, OPDA - accumulated...
In plants, growth-defense trade-offs occur because of limited resources, which demand prioritization towards either them depending on various external and internal factors. However, very little is known about molecular mechanisms underlying their occurrence. Here, we describe that cyclophilin 20-3 (CYP20-3), a 12- oxo -phytodienoic acid (OPDA)–binding protein, crisscrosses stress responses with light-dependent electron reactions, fine-tunes activities key enzymes in plastid sulfur...
Insect pests are one of the factors that most impact plant yield. The magnitude losses and spatiotemporal pest distribution in crops is a result their interactions with environment. Therefore, understanding causes production spatial patterns important for development suitable sampling plans management programs. Thus, this study aimed to quantify grain caused by insects determine pattern arthropod species Bt non-Bt corn. prevailing insect corn ears were earworm fall armyworm caterpillars...
In North America, weather and host-plant abundance drive the population dynamics of migratory pest Helicoverpa zea. The objectives this study were to (i) estimate monthly H. zea moths in Bt cotton peanut fields, (ii) document effects on trap catches, (iii) determine larval hosts supporting populations from 2017 2019. Year-round trapping was conducted 16 commercial fields two regions Florida Panhandle using delta traps. moth catches associated with temperature, rainfall, relative humidity....
The objective of this study was to determine the toxicity nine synthetic dienamides against insect pest Diaphania hyalinata (melonworm) and selectivity these substances for predator Solenopsis saevissima (fire ant). Four bioassays were conducted. To begin with, that caused high mortality D. have been selected. In second bioassay dose-mortality curves selected constructed. third bioassay, survival elapsed time kill 50% their population determined. fourth biological test, S. has evaluated....
Oligonychus ilicis is one of the most important pests that causes injury to Robusta Coffee leaves, but no data available on production protease inhibitors (PIs) in Coffea. canephora plants, either sensitive or resistant O. ilicis. This work aimed determine C. genotypes susceptible and activity PIs these genotypes. In first trial, we assessed susceptibility 14 found considerable variation. The Significant differences fecundity, net reproductive rate intrinsic population increase were observed...
Elasmopalpus lignosellus Zeller (Lepidoptera: Pyralidae), the lesser cornstalk borer (LCSB), is an economically important peanut pest in southeastern U.S. region, and its occurrence abundance have been associated with warm dry conditions. In Northwestern Florida Panhandle (USA), LCSB are unknown. Thus, a study this region used commercial sex pheromones to capture male moths year-round from July/2017 June/2021. Our results indicated that LCSBs were present April December, higher August. Moths...
Abstract Feltia subterranea (Fabricius), commonly known as the granulate cutworm, is a common species of owlet moths (Noctuidae) major agricultural importance, widely distributed in Nearctic and Neotropical regions. This study was conducted to determine biological parameters, gather information about its larval host plants, assess significance this Americas. The viability egg, larval, pupal stages, prepupal period 98, 100%, respectively, under laboratory conditions. average duration 3, 17,...
Oligonychus ilicis (McGregor) (Acari: Tetranychidae), is one of the most important mite pests found in coffee plants. One way to reduce intensive pest attacks management via resistant The purpose this study was evaluate resistance 14 C. canephora genotypes O. by antixenosis and antibiosis mechanisms determine preimaginal conditioning effect on using reared canephora. Resistance not found; however, nine showed an mechanism. Two these a more persistent than canephora, which indicated that...
