NSKE is a pesticide that is of plant origin.
NSKE is a Neem seed kernel extract that is extracted from neem seeds, thus plant-based.
Remove the outer seed coat and use only the kernel. If the seeds are fresh, 3 kg of the kernel is sufficient. If the seeds are old, 5 kg is required. Pound the kernel gently and tie it loosely with a cotton cloth. Soak this overnight in a vessel containing 10 litres of water. After this, it is filtered.
On filtering, 6 - 7 litre of the extract can be obtained. 500 - 1000 ml of this extract should be diluted with $$9\frac{1}{2}$$ or 9 litres of water. Neem Kernel extracts (500 to 2000 ml) are required per tank (10 liters capacity). 3 - 5 kg of neem kernel is required for an acre.

The number of chambers in the heart of the cockroach is 13.
The heart of the cockroach consists of an elongated muscular tube lying along the mid-dorsal line of the thorax and abdomen. It is differentiated into funnel shaped chambers with ostia on either side. Blood from the sinuses enters the heart through ostia and is pumped anteriorly to the sinuses again.
The blood vascular system of the cockroach is an open type Blood vessel are poorly developed and open into space (haemocoel). Visceral organs located in the haemocoel are bathed in blood (haemolymph). The haemolymph is composed of colourless plasma and haemocytes.

The economic threshold for monitoring Heliothis-armigera by pheromone trap in the gram field is 4 - 6 adults/trap/night.
A pheromone trap is a type of insect trap that uses pheromones to lure insects. Pheromone traps are used both to count insect populations by sampling and to trap pests such as clothes moths to destroy them.
Helicoverpa armigera is known as the cotton bollworm, corn earworm, Old World (African) bollworm, or scarce bordered straw. The larvae feed on a wide range of plants, including many important cultivated crops. It is a major pest in cotton and one of the most polyphagous and cosmopolitan pest species.
