Monitoring of diamondback moth (Plutella xylostella L) population on cabbage and Chinese cabbage over the past eight years has indicated that heavy rains from June to September limit the population of the insect. Therefore, during the dry period when diamondback moth is a serious pest, water was applied by sprinkler system placed 1.5 m over the cabbage crop rather than by traditional furrow irr...

Populations of the gypsy moth, Lymantria dispar (L.), are extensively monitored in the United States through the use of pheromone-baited traps. We report on use of automated pheromone-baited traps that use a recording sensor and data logger to record the unique date-time stamp of males as they enter the trap. We deployed a total of 352 automated traps under field conditions across several U.S. ...

Studies were conducted with codling moth, Cydia pomonella L., to fit cumulative curves for the occurrence of injured fruits and male moth catches in sex pheromone-baited traps as a function of accumulated degree-days after the start of moth flight. Twelve data sets were collected from seven apple, Malus domestica Bordhausen, orchards in Washington State from 2003 to 2006. Cumulative data were g...

The identity, geographical distribution, and host range of codling moth is reviewed, and the evidence for sweet cherry being a host is critically analysed. A model is described which assesses the risk of codling moth being spread through international trade in sweet cherries, as exempli"ed by exports from, respectively, New Zealand and USA to Japan in winter and summer. The model is based on th...

Traps baited with ethyl (E, Z)-2, 4-decadienoate (pear ester) or (E, E)-8,10-dodecadienol (codlemone) were used to monitor codling moth, Cydia pomonella L., (Lepidoptera: Tortricidae) in 102 apple,Malus domestica Borkhausen, orchards. All orchards were treated with 500Ð1,000 Isomate-C PLUS dispensers/ha during 2000Ð2002. Traps baitedwith pear ester caught their Þrst moth signiÞcantly later on a...

Indicator taxa are often proposed as efficient ways of identifying conservation priorities, but the correlation between putative indicators and other taxa has not been adequately tested. We examined whether a popular indicator taxon, the butterflies, could provide a useful surrogate measure of diversity in a closely related but relatively poorly known group, the moths, at a local scale relevant...

The study was conducted to appraise the in-depth scenario of socio-economic status of pig rearers, management practices in pigs and to identify constraints in rural areas of Kamrup and Darrang districts of Assam. A base line survey was conducted and a total of 300 pig owning households were interviewed randomly. In the study, it was found that majority of rearers were women (84.7%) for the purp...

Predation of gypsy moth egg masses was studied in Slovakia from 1999 –2002. Predation on naturally laid egg masses was recorded and linear regression was used to test the hypothesis that predation follows a type II vs. type III functional response. We also investigated the role of egg mass predation in gypsy moth population dynamics. The relative contribution of invertebrates vs. vertebrates as...
