The present study was carried out under artificial rainfall conditions to determine the details of rainfall effect on a DBM population on cabbage. Although most DBM eggs laid on the upper leaf surface were washed off with precipitation of 17.3 mm in 1 h with drops of 2.5 mm in diameter, few eggs laid on the lower surface were washed off. Under the same rain conditions as for the eggs, the falling rate of larvae decreased with advancing larval stadium except for the 1st larval stage. The number… Expand

Studies on Seasonal Abundance of Diamondback Moth Plutella Xylostella (Lepidoptera: Yponomeutidae) On Cauliflower Crop
TLDR
Survey data of three localities of Aligarh district showed that initial infestation by P. xylostella occurred when the farmers started transplantation of cauliflower seedlings, and the rate of parasitization was quite low, while rainfall negatively affected the DBM population in 2004-2005 and 2005-2006. Expand
Incomplete control of the diamondback moth, Plutella xylostella, by the parasitoid Cotesia vestalis in a cabbage field under tropical conditions
TLDR
It is concluded that under tropical conditions in which P. xylostella populations grow rapidly, combined with a high probability of recolonization from surrounding areas, biological control by a well-established specialist parasitoid reaches its limits and additional control measures are necessary.

Theoretical study of the effects of rainfall on the population abundance of Diamondback moth, Plutella xylostella
Change in Diamondback moth (DBM) Plutella xylostella (L.), number on head cabbage (Brassica oleracea var. capitata) was monitored for 15 months before the release of its natural enemies DiadegmaExpand
Population dynamics of the diamondback moth, Plutella xylostella (L.), in northern China: the effects of migration, cropping patterns and climate.
TLDR
Based on climate and using the timing of the initial peak in pheromone trap captures as a biofix, the timingof emergence of the next generation can be forecast, and more effective scouting and regional management strategies against this pest can be developed. Expand
Host-Plant Specific Feeding Relationships and Insect Developmental Stage Modulate the Impact of Rainfall on Diamondback Moth Larvae
Abstract The impact of simulated rainfall on diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), larvae depends on their stage-specific feeding behavior, physicalExpand
Diamondback moth egg susceptibility to rainfall: effects of host plant and oviposition behavior
TLDR
On common cabbage plants, oviposition patterns reduce the potential impact of rainfall on eggs, possibly reducing the effect of this important abiotic mortality factor in the field. Expand
Seasonal abundance of Plutella xylostella (Lepidoptera: Plutellidae) and diversity of its parasitoids along altitudinal gradients of the eastern Afromontane
TLDR
The diversity of wild crucifer species increased with altitude but was twice as diverse in the high zone of Mt. Kilimanjaro than the high zones of Taita hills. Expand
Population Dynamics and Seasonal Abundance of the Beetle Oryctes owariensis Beavois, 1807 (Coleoptera: Scarabaeidae: Dynastinae) in Raphia Palms in Bayelsa State, Nigeria
TLDR
The result showed that the beetle had one generation per year, was nocturnal with seasonal activity spreading out from dusk to dawn, and the high efficiency of the light traps as capture/ monitor tools in ascertaining the seasonal abundance of Oryctes owariensis beetle in raphia palm farms is a possibility for use in Integrated Pest Management Programs.

Incidence of the Major Brassica Pests in Northwestern Spain
TLDR
To determine the abundance and relative importance of the main Lepidoptera pests of Brassica crops for 6 yr at five localities in northwestern Spain and to relate the seasonal changes of larval populations and environmental conditions, pheromone traps were used as a method of monitoring adults. Expand
Biotic factors are more important than abiotic factors in regulating the abundance of Plutella xylostella L., in Southern Brazil
TLDR
Results show the importance of larval parasitoids complex in regulating P. xylostella population and that the temperature and rainfall recorded during field experiments did not influenced pest abundance. Expand

TLDR
A synthetic pheromone lure is now available for trapping to survey the diamondback moth populations and is expected to permit a reduction of the number of insecticide spray applications without loss of yield and marketability. Expand
Field Development of Resistance to Bacillus thuringiensis in Diamondback Moth (Lepidoptera: Plutellidae)
TLDR
The results suggest that the potential for resistance development in pest populations is an important consideration for deployment of B. thuringiensis toxin genes in genetically-engineered crop plants and use in related tactics. Expand
Biology, Ecology, and Management of the Diamondback Moth
TLDR
Lack of parasitoids in a particular area may have occurred because the diamondback moth is better able than its natural-enemy complex to become established in newly planted cmcifers. Expand

TLDR
The four synthetic pyrethroids remained the most potent, followed by Tokuthion,® cartap, and dichlorvos, to this highly multiresistant population of the diamondback moth. Expand
