Red Cotton Bug, Dysdercus cingulatus is a pest of cotton which suck the growing parts of the plant and attracts the bacteria which shows red lint. Ultimately it declines the crop productivity.
In this PPT slides you will come to know about the different kinds of pest which is infesting in WHEAT plant. And also you will come to know about their management practices and also you will have an knowledge about some common chemicals which is being uses to eradicate the pests/diseases infesting in wheat plant.
Implementation and impact of IPM. Safety issues in pesticide use. Political, ...Nikhil Kumar
IPM packages tested at several research centres vis-a-vis the farmers’ practices indicate superiority of the former. IPM practices enabled reduction in the number of chemical sprays. IPM system also resulted in increase of natural enemies by three-fold, reduced the insecticide and environmental pollution (Dhaliwal and Arora, 1996).
An integrated strategy for the management of major pests and diseases is possible by
I. breeding new varieties with built-in resistance,
II. evolving efficient methods of pest control through pest surveys and monitoring, and
III. biological control of pests with the help of conservation and augmentation of natural enemies like parasites, predators and insect pathogens.

The
Thrips (order Thysanoptera) are minute (mostly 1 mm long or less), slender insects with fringed wings and unique asymmetrical mouthparts. Different thrips species feed mostly on plants by puncturing and sucking up the contents, although a few are predators. Entomologists have described approximately 6,000 species.

This presentation, created by Syed Faiz ul Hassan, explores the profound influence of media on public perception and behavior. It delves into the evolution of media from oral traditions to modern digital and social media platforms. Key topics include the role of media in information propagation, socialization, crisis awareness, globalization, and education. The presentation also examines media influence through agenda setting, propaganda, and manipulative techniques used by advertisers and marketers. Furthermore, it highlights the impact of surveillance enabled by media technologies on personal behavior and preferences. Through this comprehensive overview, the presentation aims to shed light on how media shapes collective consciousness and public opinion.
This presentation by Morris Kleiner (University of Minnesota), was made during the discussion “Competition and Regulation in Professions and Occupations” held at the Working Party No. 2 on Competition and Regulation on 10 June 2024. More papers and presentations on the topic can be found out at oe.cd/crps.

0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.

5. Occurance
Moths are recorded to be warm tropic.
Most abundant in rainy season.
Active from may to october.
During active period it complete 4-5 generations.
Humid and high temperature is considered important for
insect abundance.
6. Identification
Eggsare creamy white.
Eggs are laid in batches along
the midrib of the leaf blade .
Eggs are 0.90mm long and
0.39mm wide.
Eggs are oval in shape.
7. Larvaeare light yellow or
greenish yellow
Young Larvae are 1.5-2mm long and
0.3mm wide. Fully grown larva is
20-25mm long.
Body turn green after larvae start feeding.
8. Newly formed pupa is light brown
but turns reddish brown .
Pupation take place in loose
silken web in between leaf sheath
9. Adultare golden or
yellowish brown.
Wings have 2-3 dark stripes
Moths are 10-12mm long.
Wings expense is 13-15mm.
10. Life cycle
EGG LARVA
ADULT PUPA
Eggs hatch in a
week
Larval
stage
complet
e in 5
weeks
Pupal stage last
for 2 weeks
The life cycle
complete in 5
weeks.
11. Damage
During high insect population densities, rice plants dry up and appear scorched.
Before feeding, the larvae fold the leaves longitudinally and fasten leaf margins with
stitches of threadlike silk.
The larvae feed by scraping the green mesophyll
from within the folded leaves . This results in
pale white stripe damage to the leaf.
after feeding on one fold for 2-3 days,
it moves to another leaf.
each larva destroys a number of leaves during its growth.
12. Feeding reduces photosynthetic ability of rice plant.
The damaged leaves serve as entry points for fungal and bacterial infections.
The maximum yield loss due to feeding on the flag leaf.
13. Control
CULTURAL CONTROL:-
trapping the moths by light traps.
Removal of grassy weeds from rice fields and surrounding borders prevents
the buildup of rice leaf- folders on alternate hosts.
BIOLOGICAL CONTROL:-
frogs and toads are considered predators of leaf folders.
Trichogramma spp. Is effective parastoid.
Numerous natural enemies normally push rice leaf folders below economic threshold
levels.
diptera
(Megaselia scalaris)
Hymenoptera
(Trichogramma spp.)
Coleoptera
(Coccinella spp.)
14. CHEMICAL CONTROL:-
use of nitrogenous fertilizer in split applications is
recommended.
Microbial insecticides, particularly Bacillus
thuringiensis (Acrobe,leptox ) is effective against
larvae.
Application of cartap G 9kg/acre .
(cartep hydrochloride)
Application of chlorpyrisfos EC 1000ml/acre.
15. RESEARCH
More than 18,000 rice varities from the germplasm collection
of IRRI have been screened for resistance to Cnaphalocrocis
medinalis. Nearly 115 were found resistant or moderately
resistant. Several rice varieties such as Ptb 21, Ptb 33, TKMI,
TKM2, TKM6, Muthuman- ikam, and WC1263, are resistant to
Cnaphalocrocis medinalis.
