ARTHROPOD BIOLOGY Size and Chemical Composition of Heliothis virescens (Lepidoptera: Noctuidae) Spermatophores
The tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), is a polyandrous species of economic importance on the American continent. This sexual behavior allows for the presence of multiple spermatophores inside a female and the possibility of different males fertilizing the femaleÕs offspring, which can make insecticide resistance management or sterile insect release programs par...
متن کاملThe phylogeny of the Noctuidae (Lepidoptera)
A new phylogenetic system of the Noctuidae is proposed. The system should, however, be regarded as provisional because it is primarily based on only two character complexes: the male genitalia and the tympanal region. The presence of preabdominal brush-organs and the length of tibial spurs in the adult male, the presence of a ventral cervical gland and the lack of the SV 2 setae on the first ab...
متن کاملEffect of Particle Size Distribution and Chemical Composition on Properties of Magnesia Chromite Bricks
The present study was undertaken to improve the quality and increase the life time of magnesia-chromite refractory bricks used in the copper and lead industries. The results show that a decrease in the amount of large chromite particles in the formulation improves the thermomechanical properties and also reduces the slag penetration in the bricks. In addition it was also observed that the use o...
متن کاملlanguage learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Helicoverpa zea (Lepidoptera: Noctuidae) and Spodoptera frugiperda (Lepidoptera: Noctuidae) Responses to Sorghum bicolor (Poales: Poaceae) Tissues From Lowered Lignin Lines
The presence of lignin within biomass impedes the production of liquid fuels. Plants with altered lignin content and composition are more amenable to lignocellulosic conversion to ethanol and other biofuels but may be more susceptible to insect damage where lignin is an important resistance factor. However, reduced lignin lines of switchgrasses still retained insect resistance in prior studies....
