Life History Comparison Of Two Green Lacewing Species Chrysoperla Johnsoni And Chrysoperla Carnea (Neuroptera: Chrysopidae), Kaushalya G. Amarasekare, Peter W. Shearer
Life History Comparison Of Two Green Lacewing Species Chrysoperla Johnsoni And Chrysoperla Carnea (Neuroptera: Chrysopidae), Kaushalya G. Amarasekare, Peter W. Shearer
Agricultural and Environmental Sciences Faculty Research
We investigated the life histories of two green lacewing species, Chrysoperla johnsoni Henry, Wells, and Pupedis from western North America, and Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) from western Europe in the laboratory. There were both similarities and differences in their life history characteristics. C. johnsoni exhibited a significantly longer developmental time for egg, first instar, and pupal stage than C. carnea. C. carnea exhibited a significantly shorter egg to adult developmental time than C. johnsoni. Except for the pupal stage, the survival of all other life history stages was not species-specific. All C. carnea pupae were able to develop …
Preharvest Quarantine Treatments Of Chlorantraniliprole, Clothianidin, And Imidacloprid-Based Insecticides For Control Of Japanese Beetle (Coleoptera: Scarabaeidae) And Other Scarab Larvae In The Root Zone Of Field-Grown Nursery Trees, Jason B.

Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), is an important quarantine pest of nurseries. Nursery plant movement from P. japonica-infested regions is regulated by the U.S. Domestic Japanese Beetle Harmonization Plan (DJHP), which classifies states by risk categories. Treatments for category 2 states include preharvest soil surface treatment of nursery plants grown in field soil using Discus SC, Marathon (1G or 60 WP), or Flagship (0.22G or 25 WG). In this study, Discus, Marathon 60 WP, or Flagship 0.22G DJHP standards were compared with labeled rates of non–DJHP-approved insecticides, including neonicotinoids clothianidin (Arena 50WDG), generic imidacloprid (Quali-Pro Imidacloprid 2 F …
Comparing Effects Of Insecticides On Two Green Lacewings Species, Chrysoperla Johnsoni And Chrysoperla Carnea (Neuroptera: Chrysopidae), K. G. Amarasekare, P. W. Shearer

This study compared lethal and sublethal effects of five insecticides, chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin, on adult and second instars of two green lacewing species, Chrysoperla carnea (Stephens) and Chrysoperla johnsoni Henry, Wells and Pupedis (Neuroptera: Chrysopidae) in the laboratory. Formulated pesticides were tested using concentrations equivalent to the high label rate dissolved in 378.5 liters of water. Novaluron and lambda-cyhalothrin were toxic to larvae and no treated larvae survived to the adult stage. Larva to adult survival was reduced in chlorantraniliprole, cyantraniliprole, and spinetoram treatments. Larva to adult developmental time and sex ratio were not different among the …
Laboratory Bioassays To Estimate The Lethal And Sublethal Effects Of Various Insecticides And Fungicides On Deraeocoris Brevis (Hemiptera: Miridae), K. G. Amarasekare, P. W. Shearer
Laboratory Bioassays To Estimate The Lethal And Sublethal Effects Of Various Insecticides And Fungicides On Deraeocoris Brevis (Hemiptera: Miridae), K. G. Amarasekare, P. W. Shearer
Agricultural and Environmental Sciences Faculty Research
This laboratory bioassay focused on lethal and sublethal effects of five insecticides (chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin) and two fungicide treatments (sulfur and a mixture of copper hydroxide and mancozeb) on the predatory mired bug, Deraeocoris brevis (Uhler) (Hemiptera: Miridae) using second instars and adult males and females. Formulated pesticides were tested using concentrations that were equivalent to the high label rate (1x) (high rate) and 1/10th of that amount (0.1x) (low rate) dissolved in 378.5 liters of water. Lambda-cyhalothrin was highly toxic to D. brevis nymphs and adults at both rates, whereas both rates of novaluron were highly …

A comparative proteomics study using isobaric tags for relative and absolute quantitation (iTRAQ) was performed on a mesophytic tomato (Solanum lycopersicum) cultivar and a dehydration-resistant wild species (Solanum chilense) to identify proteins that play key roles in tolerance to water deficit stress. In tomato ‘Walter’ LA3465, 130 proteins were identified, of which 104 (80%) were repressed and 26 (20%) were induced. In S. chilense LA1958, a total of 170 proteins were identified with 106 (62%) repressed and 64 (38%) induced. According to their putative molecular functions, the differentially expressed proteins belong to the following subgroups: stress …
