Pollination determines the life of flowers, fruits and crops. It is estimated that every third morsel we consume is a result of pollination. The honey bee is among the most effective pollinators. 90 per cent of pollination in cross-pollinated crops like oil-seeds, vegetables, fruits and cereals is aided by honey bees alone. According to the National Bee Board, Government of India, honey bees help increase yields of fruits like pear, litchi and apple, to the extent of 240–6,014%, 4,538–10,246% and 180–6,950% respectively. So, honey bee pollination is paramount in the cultivation of food crops. Similarly, certain insects such as ladybird beetle, chrysoperla and trichograma are beneficial to crops. Being naturally available, these insects are vital farming inputs available to farmers at no cost. However, they face a real threat of eradication by most insecticides used in fields today.
Farmers in warm and tropical countries generally experience pest attack and honey bee pollination at around the same time. However, the use of pesticides such as neonecotinoids aimed at the former, works by eliminating both. If used at the flowering stage, this results in drastically reduced yields. An ideal pesticide is characterised by effectiveness against target pests, but softness towards pollinators and beneficials. One of the few pesticides with this virtue is Endosulfan. Endosulfan is comparable only to neem in terms of its softness on honey bees.
Endosulfan in IPM systems: Endosulfan is an excellent tool for precision farming. While being soft on beneficial insects, it eliminates 60 kinds of pests that attack 29 crops including cereals, legumes, oilseeds, fruit, nuts, vegetables, cotton and ornamental plants….http://www.whybanendosulfan.org/pollinators-and-beneficials.htm
