Behavioral responses of adult female tobacco hornworms, Manduca sexta, to hostplant volatiles change with age and mating status

open access: yesJournal of Insect Science, 2002
We present evidence for two behaviors influenced by intact, vegetative plant odor -- upwind flight and abdomen curling -- in female Manduca sexta and demonstrate the influence of the age and mating status of the moths on these behaviors.

Does water intake after oviposition indicate the end of oviposition and egg depletion in Odonata females?

open access: yes, 2015
Oviposition in odonate females is usually considered finished when the female leaves the oviposition site. However, considering that many species lay their eggs within a set of bouts it is difficult to distinguish between the end of the oviposition bout ...

Lack of fitness cost associated to CYP9K1‐mediated insecticide resistance in Anopheles funestus, represents a threat to vector control

open access: yesPest Management Science, EarlyView.
The 454A‐CYP9K1‐mediated resistance confers fitness advantages regarding pupation and longevity in Anopheles funestus, resulting to a slow susceptibility reversion. By contrast, the 119F‐GSTe2 resistance allele rapidly declines. Abstract BACKGROUND Resistance management is critical to maintain insecticide effectiveness in malaria control, and ...

The role of urea in the oviposition behaviour of Japanese encephalitis vectors in rice fields of South India

open access: yesMemorias do Instituto Oswaldo Cruz, 2003
The effect of urea on the oviposition behaviour of culicine vectors of Japanese encephalitis was studied in rice fields. Gravid females had a strong preference for oviposition in urea treated areas in rice fields, while no such preference was exhibited ...

SOME OBSERVATIONS ON OVIPOSITION IN THE FOWL [PDF]

open access: yesQuarterly Journal of Experimental Physiology and Cognate Medical Sciences, 1953
1. Six out of nine hens were able to lay their eggs after spinal transections, but the process took much longer than normal.2. Ovulation was almost completely inhibited in the spinal birds.3. Observations at laparotomy show that during oviposition the uterus is not everted as claimed by Wickmann, but that the egg passes from the uterus into the vagina ...

Integrating bioassays and transcriptomics to detect neonicotinoid resistance in Australian Bemisia tabaci MEAM1

open access: yesPest Management Science, EarlyView.
The Bemisia tabaci MEAM1 strain GR15‐1R shows partial resistance to neonicotinoids (bottom), which correlates with an increased expression of the P450 gene CYP6CM1 compared to the insecticide‐susceptible strain SU07‐1 (top). Abstract BACKGROUND Bemisia tabaci MEAM1 is a highly invasive and polyphagous pest species of agricultural and horticultural ...

Variation of the Oviposition Preferences of Aedes aegypti in Function of Substratum and Humidity

open access: yesMemorias do Instituto Oswaldo Cruz, 2002
Two Aedes aegypti (L.) populations were studied in the laboratory regarding the preference for three types of breeding sites, i.e., flasks containing only water, flasks with a plant and flasks with a stick.
