Lygus species of plant-feeding insects have emerged as economically important pests cotton in the United States. These are not controlled by commercial Bacillus thuringiensis (Bt) varieties resulting economic losses and increased application insecticide. Previously, a Bt crystal protein (Cry51Aa2) was reported with insecticidal activity against spp. However, transgenic plants expressing this did exhibit effective protection from feeding damage. Here we employ various optimization strategies,...
The spectrum of insecticidal activity Cry51Aa2.834_16 protein targeting hemipteran and thysanopteran insect pests in cotton was characterized by selecting screening multiple pest non-pest species, based on representation ecological functional groups, taxonomic relatedness (e.g. relationship to species where observed), availability for effective testing. Seven invertebrate orders, comprising 12 families 17 representative were screened susceptibility and/or the ability protect against feeding...
Sweet corn (Zea mays L. var. saccharata) is a specialty type of maize primarily consumed after roasting. Despite its growing demand, cultivation remains limited in Pakistan, and no officially approved sweet variety has been available for general cultivation. The development high-yielding, disease-resistant crucial to reducing import dependency enhancing local production. Objective: To develop evaluate suitable focusing on agronomic performance, disease resistance, yield potential. Methods:...
Abstract BACKGROUND Plant bugs ( Lygus spp.) and thrips Thrips are two of the most economically important insect pest groups impacting cotton production in USA today, but not controlled by current transgenic varieties. Thus, seed or foliar‐applied chemical insecticides typically required to protect from these groups. Currently, pests resistant several insecticides, resulting fewer options for viable management. Previous publications documented efficacy event MON 88702 against plant limited...
Lygus lineolaris (Palisot de Beauvois) and hesperus Knight are among the most important pests affecting production of cotton in United States. spp. use a cell rupture feeding strategy. However, precise stylet-probing behaviors adult not well understood or quantifiably related to damage. The long-term goals our research to: 1) relate stylet probing damage, 2) quantitatively compare L. resistant susceptible host plants. specific objectives this study were apply latest technology...
Probing behavior of Lygus lineolaris (Palisot de Beauvois) has previously been characterized with electropenetrography (EPG). Cell rupturing (CR) and ingestion (I) EPG waveforms were identified as the two main stylet-probing behaviors by adult L. lineolaris. However, characterization identification are not complete until specific events a particular waveform correlated to insect probing. With use EPG, histology, microscopy, chemical analysis, probing on pin-head cotton squares was studied....
Lygus lineolaris (Palisot de Beauvois) is one of the most important pests on cotton in United States. Previous research showed that transgenic plants expressing Bacillus thurigiensis (Bt) crystalline protein Cry51Aa2.834_16 (designated MON 88702) have insecticidal effects nymphal L. lineolaris. The present study first to examine a Bt-expressing feeding by heteropteran like We compared stylet probing behaviors third-instar nymphs pin-head squares (i.e., buds <3 mm wide) 88702 versus...
Susceptibility of the sugarcane borer, Diatraea saccharalis (F.), to tebufenozide was measured using a feeding bioassay, and values obtained were compared with baselines generated before use this insecticide in Louisiana sugarcane, Saccharum spp. Results from our study suggest that susceptibility is decreasing field-collected borers. Inflections log dosage-probit lines detected for many field collections, indicating increased heterogeneity within these populations response tebufenozide....
AgCenter Sugar Research Station, St. Gabriel, La (Iberville Parish).Eight different insecticide treatments, in addition to an untreated check, were evaluated for season-long control of SCB RCB design with five replications a field 'HoCP91-555' plant cane planted Aug 2003.Insecticide treatments applied 3-row plots (6 ft × 30 ft) on 10 Jul and 9 using CO 2 sprayer mounted all-terrain vehicle 8005 flat-fan nozzle (one per row) delivering gpa at 35 psi.Prior test initiation, Lorsban 15G (15...
