sexual behavior in most moths is limited to a precise duration period of either the day or the night. these behaviors as well as the calling behavior are specific. information on reproductive behavior is important in the chemical ecology studies. experiments were conducted to determine the developmental biology, adult time emergence and calling behaviors of three populations of carob moth, ecto...

This study was carried out to determine the effects of acetic acid, hot water, and cold sand stratification scarification at different periods on seed germination carob (Ceratonia siliqua L.) in Salah Alden province. The seeds were collected from Kirkuk province area September 2016. Carob stratified not treated by soaking glacial acid for 20, 40, 60, 120 min. lab temperature (25oC). Hot water (...

Gypsy moth defoliation of oak trees has been shown to lead to increased tannin levels, which, in turn, lead to reduced gypsy moth growth and fecundity. In laboratory experiments, increased tannin levels can interfere with the transmission of a virus that is consumed by larvae on oak foliage, and high mortality rates of larvae in the field are sometimes associated with low levels of defoliation....

Many genes of large double-stranded DNA viruses have a cellular origin, suggesting that host-to-virus horizontal transfer (HT) of DNA is recurrent. Yet, the frequency of these transfers has never been assessed in viral populations. Here we used ultra-deep DNA sequencing of 21 baculovirus populations extracted from two moth species to show that a large diversity of moth DNA sequences (n = 86) ca...

Results After 80% ammonium sulphate precipitation, most of the proteins were recovered in 80% precitable fraction, 58.4% in moth and 71.2% in rice weevil. However, the recovery in supernatant was low 6.1% in rice weevil and 14.4 in moth extract. In ELISA inhibition of both the insect WBEs, most of the allergenic activity was recovered in 80% ammonium sulphate precipitate fraction (80% ppt). No ...

in 2005, during a survey on the biology of grape berry moth, lobesia botrana (denis & schiffermã¼ller) in nazlochay of urmia region, some damaged symptoms of another moth on the berries of grape were observed that caused by a coleophorid species determined as coleophora hemerobiella (scopoli). this species, which is newly reported from iran, also may be considered as a new pest of vineyards of ...

The nutritive value of Ceratonia siliqua and Gleditsia triacanthos pods was determined on the basis of their chemical composition, in vitro gas production and rumen fermentation end-products. Medicago sativa was used as a reference feed material. The studied samples showed differences in chemical composition and phenolic compounds. Crude protein (CP) content was particulary low (80 g/kg DM) in ...

The tiger moth Bertholdia trigona is the only animal in nature known to defend itself by jamming the sonar of its predators - bats. In this study we analyzed the three-dimensional flight paths and echolocation behavior of big brown bats (Eptesicus fuscus) attacking B. trigona in a flight room over seven consecutive nights to determine the acoustic mechanism of the sonar-jamming defense. Three m...

Winter moth, Operophtera brumata, originally from Europe, has invaded eastern Massachusetts causing widespread defoliation and damage to many deciduous tree species and a variety of crop plants in the infested area. We identified O. brumata nucleopolyhedrovirus (OpbuNPV) in winter moth larvae collected from field sites in Massachusetts by using PCR to amplify a 482 bp region of the baculovirus ...
