Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Integrated Pest Management In and Around the Home

Carpenter bees build nests in wood,
creating galleries that can weaken
structures; however, they rarely cause
severe damage. People may be fright-ened
by carpenter bees because of their
large size, their similarity to bumble
bees, and their annoying noise.
IDENTIFICATION
Most carpenter bees, Xylocopa spp., are
large and robust insects resembling
bumblebees. Females range from about
5/8 to 1 inch long and are shiny black
or with metallic blue reflections. Their
abdomens are shinier than those of
bumblebees with fringes of hairs on
some segments. Males usually have
pale hair on the thorax and the male
valley carpenter bee is golden brown
(Figures 1 and 2).
LIFE CYCLE
Female carpenter bees bore into sound
wood, and sometimes decaying wood,
to make nests (Figure 3). Nests usually
consist of tunnels 1/2 inch in diameter
and 6 to 10 inches deep that are par-titioned
into several chambers, each
containing an egg and a supply of
food (pollen). Carpenter bees may use
old tunnels for their nests, which they
occasionally enlarge; several bees may
use a common entry hole connecting to
different tunnels. Over a period of time,
tunnels may extend as far as 10 feet
into wood timbers. Tunnels are vacated
after the brood’s larval and pupal
stages complete their development. De-velopment
from egg to adult may take
about 3 months. New adults emerge in
late summer, feed on nectar and pollen
and overwinter, often in old tunnels
they have provisioned with pollen.
They emerge in spring to mate, cre-ate
and provision nests, and lay eggs.
There is only one generation a year.
DAMAGE
Carpenter bees cause damage to
wooden structures by boring into
timbers and siding to construct nests.
The nests weaken structural wood and
leave unsightly holes and stains on
building surfaces. Sound, undecayed
wood without paint or bark is usu-ally
selected for nests. Carpenter bees
also frequently attack dead wood on
trees or lumber from southern yellow
pine, white pine, California redwood,
cedar, Douglas fir, cypress, mimosa,
mulberry, ash, and pecan trees. They
avoid most hardwoods. The presence
of carpenter bees around buildings and
wooden structures can be annoying or
even frightening; however, males can-not
sting and females sting only when
provoked or handled roughly.
MANAGEMENT
Prevention is the main approach to
managing carpenter bees. If pos-sible,
susceptible exterior parts of a
building should be constructed out of
hardwoods, which are not normally
attacked by the bees for nest building.
On all buildings, fill depressions and
cracks in wood surfaces so they are less
attractive. Paint or varnish exposed
surfaces regularly to reduce weather-ing
and attack by bees. Fill unoccupied
holes with steel wool and caulk to
prevent their reuse. Wait until after
bees have emerged before filling the
tunnels. Once filled, paint or varnish
the repaired surfaces. Protect rough ar-eas,
such as ends of timbers, with wire
screening or metal flashing.
Carpenter bees are generally consid-ered
beneficial insects because they
help pollinate various crop and non-crop
plants. Under most conditions
their damage can be successfully man-aged
using the preventive measures

methods of control. To do this, treat
tunnels with adult bees in early spring
before nesting activity has begun, or in
fall after all adult bees have emerged
and are settling in to hibernate through
the winter. It does little good to treat
active nests (those containing eggs,
larvae, or pupae) in late spring to sum-mer
as indicated by females bringing
in loads of pollen, since each brood
chamber is sealed with partitions of
wood particles at each end which pro-hibits
pesticides from penetrating to
the brood. These developing bees can
chew their way out after the pesticide
is no longer viable. It is best to treat at
night when the adults have returned to
the tunnel. Wait a day or two after the
treatment before sealing the tunnel to
make sure all adults have been exposed
to the insecticide.
Apply dust formulations of insecticides
or desiccant dusts into nest holes with a
bulb applicator. Dusts containing pyre-thrin
(Drione Dust), borate or disodium
octaborate tetrahydrate (Tim-bor), and
pyrethroids including deltamethrin
(Bonide Termite and Carpenter Ant
Dust) and cyfluthrin (Tempo Dust) are
currently labeled for use against car-penter
bees. Avoid inhaling these ma-terials,
because they can cause serious
lung irritation. Many of these products
are available only to licensed pest con-trol
professionals. After the adults are
killed, repair and fill holes with steel
wool and caulking, then repaint or
varnish the repaired surfaces.
