In RARS Jessore, it has been found a huge number of stripped squirrels ((Funambulus pennanti) damaged the young green and premature coconut trees, mangoes, jackfruit, litchi, sapota, guava, ber, bael and other fruit trees. On the other hand, when the litchi, mango and guava fruits were mature the squirrel damaged the fruit by eating voraciously. We observed some of the coconut trees where green young fruits were damaged by rats as well as brown squirrels. we counted the average number of squirrels per fruit tree. The average number of striped squirrels were 2, 1, 0.5, 1, 0.5, 0.5, and 0.5 per plant observed in mango, coconut, jackfruit, litchi, guava, sapota and ber fruit plant, respectively while in ARS, Daulatpur, we observed stripped squirrels in number 1, 1, 0.5, 0.5, 0.5, and 0.5, from the above mentioned fruit plants. Similarly in Fruit Research Station,Binodpur, Rajshahi, the number of stripped squirrels were 2, 2, 0.5, 1 0.5, 1, and 0.5 observed on Mango, coconut, jackfruit, litchi, guava, sapota and ber, respectively. We also observed Resional Wheat Research Sub Station Shyampur, Rajshahi for investigating the squirrel damage. It was found that there were many stripped squirrel roaming on in the coconut trees. About 3-5 squirrels observed per coconut tree and most of the young coconuts were damaged by squirrel. They cause damage to the coconut by boring and feeding up the pulp. The damaged coconuts were dropped under the tree on the ground. The squirrels also built their nest on the tree by cutting leaf and other parts of the coconut trees. In RARS, Akbarpur, Moulvibazar, it has been found a huge number of brown squirrels (Callosciuruspygerythrus G) damaged the young green off season jackfruit and young shoots of mango, litchi and jackfruits trees. On the other hand, when the litchi, mango and guava fruits were mature the squirrel damaged the fruit by eating voraciously. We observed some of the coconut trees where green young fruits were damaged by rats as well as brown squirrels per Jackfruit, mango and litchi trees. The numbers of brown squirrels (C. piggerythrus) were observed 1, 1, 1, 0.5, 0.5, 0.4 and 0.3 per tree of mango, coconut, jackfruit, litchi, guava, sapota and bael plants, respectively. Observation were made in the RARS, Hathazari, Chittagong, Regional Hill Agriculture Research Station Khagrachari, HARS, Ramgarh, during March, 2015. It has been observed that a lot of brown squirrels (Callosciurus pygerythrus G.) have been found to damage different fruit trees grown in the garden. In RARS Hathazari, numbers of brown squirrels were observed 2, 1, 1, 1, 1 0.5, 0.5 and 0.5 per tree of mango, coconut, jackfruit, litchi, guava, sapota, ber and bael plants, respectively. In Hill Agriculture Research Station, Ramgarh, during March, 2015, the numbers of brown squirrels were observed 2, 1, 1, 0.5, 0.5, 0.5, 0.5,and 0.4 per tree of mango, coconut, jackfruit, litchi, guava, sapota, ber and bael plants, respectively. When the litchi, mango and guava fruits were matured the brown squirrels and different species of birds namely, crow, myna, martin, bulbul etc. damaged these fruits by eating voraciously. In the Hill Agricultural Research Station, Khagrachari, a good number of brown squirrels per plant were 1, 1, 1, 0.5,0.5, 0.5, 0.5 0.5 and 0.5 in number were found to damage mango, green coconut, jackfruits, litchi, guava, sapota, ber bael and tamarind and other citrus fruit immature and matured stages. The maximum damage of fruits caused by the squirrels were observed during April-June when the fruits were premature and matured condition. The extent of damage of the above fruits were estimated 5-10%.
