Bamboo species are susceptible to insect attack at every stage, right from seeds to the finished products. In recent past during an insect survey a beetle was found boring into green culms of standing bamboo. The beetle was collected and got identified as Phlaeobius crassicollis (Coleoptera: Anthribidae). It makes first record of this beetle's infestation on bamboo species.Keywords

Seedlings of19 important species (exotic and indigenous) were raised in nursery. These species were planted in the project area. And survival rate and height were measured. In the first year of plantation maximum survival per cent (l00 %) were recorded for Acacia delbata, Acer oblongum, Aesculus indica, Fraxinus micrantha, Grewia optiva, Prunus cerasoides and Robinia pseudoacacia. In the second year maximum survival per cent ( >90 %) were found in Acer oblongum > Robinia pseudoacacia> Grewia optiva, > Fraxinus micrantha. In the third year maximum survival per cent were recorded (>80 %) Grewia optiva > Ficus roxburghii > Acer oblongum > Ficus glomerata >Aesculus indica. Maximum height were recorded in Alnus nepalensis > Salix alba >Robinia pseudoacacia > Acacia mearnsii > Acacia melanoxylon after the completion of third year.- Germjnation of Elm (Ulmus laevlgata Royle) as Affected by Depth of Sowing

The Poplar shoot Borer E. glaciata is one of the most destructive lepidopterous pest of P. ciliata in nurseries. The biology and habits of this insect have been discussed with special reference to its life history and nature of damage. Adult of E. glaciata has a longevity of 5.60 ± 0.516 days. The females lays an average of 75 to 100 eggs. The incubation period average 5.56 ± 0.527 days. The total life cycle in laboratory reared specimen varies from 35 to 40 days. The larvae damage the apical tIPS, resulting in die-back and forking.- An Ecological Assessment of Spatial Pattern in Site Conditions in Bamboo Plantations in a Dry Tropical Region with a Comment on Clump Spacing

The role of bamboo (Dendrocalamus strictus) in causing spatial patterns in ecosystem structure and function has been studied in East Mirzapur Forest Division. The Bamboo savanna is characterized by spatial heterogeneity in form of concentric zones around the bamboo clumps showing greater productivity and soil fertility. The bamboo influence zone (about 1.25 m around the clump), having considerable input of bamboo litter and fine ischolar_mains, is characterized by greater accumulation of organic carbon and nutrients relative to the intervening herb covered zone. Compared to the herb zone, the increase in 0-30 cm soil content in the bamboo zone ranged: organic carbon 15-17 per cent, total nitrogen 7-11 per cent, available phosphorus 25-29 per cent, exchangeable potassium 20- 35 per cent. Because only <20% of the land area is strongly modified by bamboo with respect to soil fertility, it is suggested that a reduction in clump spacing may enhance the productivity of bamboo through its greater regulation of the nutrient relations as well as higher clump densities in the bamboo savanna ecosystem. The presently used clump density, therefore, needs a reappraisal.- Effect of Temperature and Relative Humidity on the Development of Sal Defoliator, Ascotis imparata Walk. (Lepidoptera: Geometridae)

Temperature and humidity are the two main factors that influence the rate of survival and development of sal defoliator, Ascotis imparata Walk. (Lepidoptera: Geometridae), which is an economically important polyphagous pest of sal and other plants in plantations and natural forest. Study of effect of temperature and humidity revealed that the best suited temperature was 25°C to 30°C with 70 to 75% relative humidity. Low temperature (10-15°C) and high humidity (80-90%) and vice - versa was found unfavourable for development and survival of the larvae of A. imparata. The o maximum survival percentage (96 per cent) of larvae was observed at the temperature 25 C with 75% o relative humidity while minimum (16%) survival was at 40°C with 60%. The optimum condition to complete the pupal development was 30°C temperature with 70% relative humidity. At this condition pupae completed development at minimum period of 14.06 days with maximum survival of 91.30 per cent.Keywords

Biological effects of six preferrential host plants including Shorea robusta, Ricinus cummunis, Murraya koenigii, Mallotus philippinensis, Syzygium cummunis and Dalbergia sissoo was studied on a polyphagous pest, Ascotis imparata Walk. Maximum fecundity (658.58± 12.5 egg / female) was observed when moth's larvae reared on sal (S. robusta) leaves. It was followed with 626.25± 15.43 eggs on castor (Ricinus cummunis) and minimum fecundity (429.92 ± 7.53 eggs) was observed when larvae reared on D. sissoo. Shorea robusta was found to be most preferred host of A. imparata among six host plants tested as minimum development time in all stages was observed including incubation of eggs (3.80 ± 0.26 days), larval development period (17 ± 0.18 days) and pupal period (14.58 ± 0.28 days). Life cycle was completed in (40.46 ± 0.22 days) which is minimum in comparison to the duration taken when reared on other five host plants.Keywords

Beetle of Phloeobius crassicollis exhibit sexual dimorphism. The emergence of beetles occurred during May-June. The newly emerged beetles feed on the outer surface of the bamboo culm recurring preferably at the nodes. Single gravid female laid 40-45 eggs at nodes/culm sheaths. The longevity of female and male beetles is 22.6±0.57 and 18.5±0.38 days respectively. The sex ratio male: female is 1.00:0.917. The freshly laid eggs are light gray and oval, incubate for 11.20±0.27 days at room temperature. The freshly hatched larvae nibble and scratch at the point of hatching on the nodes/culm sheaths. Larvae feed on woody tissues of nodes and internodes and deposit the larval frass inside the hollow internodes. The body colour of larvae was creamish with dark yellow head. The larval period was 317.6±0.14 days. Pupae were grayish black in colour. The length and breadth of pupa was 15.00 ±0.316 mm and 8.4±0.155 mm respectively. It emergedinto adults after 17.2±0.63 days.P. crassicollis taken one year to complete the life cycle.Keywords

The seeds of Anogeissus latifolia mature in second fortnight of March each year when the seed moisture content is around 12 per cent and colour of fruits turns to blackish green. Seeds are about 95% empty when collected from the trees. The germination percentage of seeds is only 1-2 per cent; however 50% seeds are sound and viable. Seeds can easily be stored at 150 C in refrigerator in polythene bags at a moisture content of 9 per cent with slight decrease in viability up to two years. In addition to infertility/emptiness of seeds insect problem was also studied using entomological inputs. To control insect attack on fruits/seeds of A. latifolia, systemic insecticides were applied in the trees in the field and after six months of insecticide application seeds were collected from treated and untreated trees and tested in laboratory. The results showed that the number of half filled seeds was increased (about 10%) over the seeds of untreated trees; however, there was no significant increase in number of filled seeds. Increase in half filled seeds of treated trees shows the effect of systemic insecticides on the suspected insect attack in the seeds of the species. These observations showed that infertility problem in the seeds of A. latifolia are related with the insect infestation and needs further detail studies.Keywords
