What Can We Learn from Dissecting Tortricid Females About the Efficacy of Mating Disruption Programs?

Insects
Female mating success for the tortricids codling moth (CM), Cydia pomonella, Oriental fruit moth (OFM), Grapholita molesta, European grape vine moth (EGVM), Lobesia botrana, and five leafroller (LR) species under various mating disruption (MD) programs ...

Larval predation on different instars in blowfly populations

Brazilian Archives of Biology and Technology, 2004
During its larval stage, Chrysomya albiceps (Diptera: Calliphoridae) is a facultative predator on other blowflies. In this study, we evaluated the predation by third instar larvae of C.

Factors Impacting the Use of an Allelochemical Lure in Pome Fruit for Cydia pomonella (L.) Monitoring

Insects
A four-component blend comprising pear ester, DMNT, linalool oxide, and acetic acid (CM4K) was identified as a potent allelochemical lure for both sexes of codling moth (CM), Cydia pomonella (L.).

Optimizing UV-A Solar-Powered Lights to Enhance Lures for Codling Moth, Cydia pomonella L. (Lepidoptera: Tortricidae)

Insects
Field trials were conducted to define several parameters associated with adding LEDs to monitoring traps for codling moth (CM), Cydia pomonella (L.), using both a sex pheromone lure (PH1X) and a non-pheromone lure (CM4K).

Identification of Instars of Hypera postica Using Chaetotaxy [PDF]

Journal of Economic Entomology, 2006
A new method using chaetotaxy for identification of instars of Hypera postica (Gyllenhal) is presented and compared with earlier methods. I recommend a combined method using separation of small (first and second instars) and large (third and fourth instars) followed by identification of particular instars by using chaetotaxy.

Active Assessment of Female Codling Moth, Cydia pomonella (L.), Mating Status Under Mating Disruption Technologies

Insects
Most assessments of sex pheromone-based mating disruption (MD) for codling moth (CM), Cydia pomonella (L.), have not included measurements of female mating.

RELATIVE SUSCEPTIBILITY TO ARSENIC IN SUCCESSIVE INSTARS OF THE SILKWORM [PDF]

Journal of General Physiology, 1926
The susceptibility of the silkworm to arsenic decreases during its larval development. Relative susceptibility may be expressed numerically as a ratio of areas under dosage-effect curves.

Development of the solitary larval endoparasitoid Glyptapanteles porthetriae (Hymenoptera: Braconidae) in its host Lymantria dispar (Lepidoptera: Lymantriidae)

European Journal of Entomology, 2000
The development of the solitary endoparasitic braconid Glyptapanteles porthetriae in gypsy moth larvae of different ages was studied. Host larvae were parasitized during the premolt to the 2nd instar (A-larvae), to the 3rd instar (B-larvae) or to the 4th

Cumulative effect of HaNPV against Helicoverpa armigera infesting Chickpea

Environment Conservation Journal, 2016
The instar-wise larval mortality in H. armigera due to HaNPV @ 0.500 ml/l showed a consistent decrease in all the five instars and cent per cent larval mortality was recorded in the first instar larvae.
