BACKGROUND Helicoverpa armigera and H. zea are amongst the most significant polyphagous pest lepidopteran species in the Old and New Worlds respectively. Separation of H. armigera and H. zea is difficult and is usually only achieved through morphological differences in the genitalia. They are capable of interbreeding to produce fertile offspring. The single(More)
BACKGROUND Developing lepidopteran microsatellite DNA markers can be problematical, as markers often exhibit multiple banding patterns and high frequencies of non-amplifying "null" alleles. Previous studies identified sequences flanking simple sequence repeat (SSR) units that are shared among many lepidopteran species and can be grouped into(More)
The highly polyphagous Old World cotton bollworm Helicoverpa armigera is a quarantine agricultural pest for the American continents. Historically H. armigera is thought to have colonised the American continents around 1.5 to 2 million years ago, leading to the current H. zea populations on the American continents. The relatively recent species divergence(More)
Helicoverpa armigera is an important pest of cotton and other agricultural crops in the Old World. Its wide host range, high mobility and fecundity, and the ability to adapt and develop resistance against all common groups of insecticides used for its management have exacerbated its pest status. An understanding of the population genetic structure in H.(More)
The lantana mealybug, Phenacoccus parvus Morrison (Hemiptera: Pseudococcidae), although had made its entry in continental India since 2012, however, was hitherto not reported to occur in northeast India. The present study reports first record of P. parvus invasion on Naga King chili, Capsicum chinense Jacquin (Family: Solanaceae) plants in the Meghalaya(More)
The pine lappet moth, Kunugia latipennis Walker (Lepidoptera: Lasiocampidae), is the major insect pest of pines found in the northeastern hilly region of India. Recently, an outbreak of lappet moths was observed in the mid-altitude hills of Meghalaya during May–June 2011. In this report, attempts are made to describe a recent outbreak of K. latipennis in(More)
