The seasonal occurrence of the beet armyworm, Spodoptera exigua (Hübner), and the southern armyworm, Spodoptera eridania (Cramer), was monitored over a 2year period using International Pheromones, Ltd. Moth Traps  baited with rubber septa impregnated with pheromone blends identified from conspecific females and also with pheromone emitted by live female beet armyworm moths. The pheromone blend...

The gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae) nucleopolyhedrovirus LdMNPV was tested as a synergist for nucleopolyhedroviruses against Helicoverpa zea (Boddie), Spodoptera exigua (Hübner), and Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) larvae. The addition of the gypsy moth NPV significantly decreased the LC50s of AcMNPV, AfMNPV, GmMNPV, HaMNPV, HzSNPV, PxMN...

Preferences of female predators for various species of prey may not correlate with nutritional value of the prey, notably with regard to resulting rates of reproduction in the female predator. This study assessed the biochemical status of adult female Podisus maculiventris (Say) as affected by prey species. Colony-reared females were fed one of Þve species of natural or factitious prey: beet ar...

this is a report on the occurrence of the hymenoterous parasitoid of the beet moth, scrobipalpa ocellatella boyd (lep.: gelechiidae), in iran for the first time. diadegma pusio (holmgren) was collected from the larvae of s. ocellatella in the sugar beet fields located in ray, the southern district of tehran. this ichneumonid species is belonging to the subfamily campopleginae and tribe limneriini.

the sugar beet moth, scrobipalpa ocellatella boyd. (lep.: gelechidae( is the specific pest of beet. the aim of the present study was to identify the parasitoids of the moth. in this regard, sampling was conducted in fields of khorasan-e-razavi province during 2010 from early july until october. larvae and pupa were collected along with tubers of sugar beet and then were reared under controlled ...

the beet moth, scrobipalpa ocellatella is recognized as a widespread agricultural pest. cold hardiness strategy of the beet moth larvae was investigated through monitoring seasonal changes at supercooling points and lower lethal temperatures. furthermore, the role of microhabitat in winter survival was studied. the mean scps of the last instar larvae was not significantly different from novembe...

this paper reports the occurrence of the hymenoterous parasitoids of the beet moth, scrobipalpa ocellatella boyd larvae in iran for the first time. two braconid species of microchelonus subcontractus abdinbekova and bracon intercessor nees were collected from the larvae of s. ocellatella in the sugar beet fields located in ray, the southern district of tehran. these parasitoids are belonging to...

The beet armyworm Spodoptera exigua (Lepidoptera: Noctuidae) is difficult to control using chemical insecticides because of the development of insecticide resistance. Several pest control agents are used to control the beet armyworm. Entomopathogenic fungi are one of the candidates for eco-friendly pest control instead of chemical control agents. In this study, among various entomopathogenic fu...

Nine pharmaceutical inhibitors of eicosanoid biosynthesis (e.g., bromophenacyl bromide, clotrimazole, diclofenamic acid, esculetin, flufenamic acid, indomethacin, nimesulide, sulindac, tolfenamic acid) that increased the susceptibility of the gypsy moth, Lymantria dispar (L.), to the nucleopolyhedrovirus LdMNPV were tested against the beet armyworm Spodoptera exigua (Hübner), the corn earworm H...
