Abstract: Shisham Dalbergia sissoo Roxb. is the most popular and valuable timber species found throughout India-Pakistan sub-continent. The present study was undertaken in the province of Jharkhand to find out the insect pest fauna of D. sissoo their infestation and seasonal incidence. Total seventeen insect pests were recorded from the region out of which five insects belongs to Coleoptera viz. Apoderus sissu, Anomala dalbergiae, Anomala bengalensis, Myllocerus undecimpustulatus and Myllocerus discolour were observed. Similarly, five insect pests of order Lepidoptera viz. Agrotis ipsilon, Plecoptera reflexa, Ascotis infixaria, Dichomeris eridantis and Leucoptera sphenograpta were observed. Six insect pests belonging to order Hemiptera viz. Lawana conspersa, Ceroplastes rusci, Leptocentrus taurus, Myzus persicae, Icerya seychellarum, Drosicha dalbergiae and Odontotermes obesus. Among these, two insect pests Lawana conspersa and Icerya seychellarum were found first time on D. sissoo. Additionally, nature of damage, seasonal incidence and their infestation was also observed during the course of study.

Abstract: The present study was conducted to clarify the fertilizer requirement on the growth and yield of the variety Bangladesh Jute Research Institute Kenaf-4. Consequently the experiment was conducted in Jute Agriculture Experimental Station, Manikganj and Jute Research Regional Station, Kishoreganj of Bangladesh Jute Research Institute. The results indicated significant effect of different NPKS levels on Bangladesh Jute Research Institute (BJRI) Kenaf-4 yield and yield contributing characters over control. The highest fibre (3.14t/ha) and stick (7.65t/ha) yield were obtained by the combination dose of N100 Kg/ha with PKS 10-60-20 kg/ha at Kishoreganj. The plant height (3.14m), base diameter (19.47mm) also found highest with the same fertilizer treatment combination. By the same treatment produced higher fibre yield and yield contributing characters at Manikganj though that yield was slightly lower than Kishoreganj. Economic analysis suggested the best combination is N100P10K60S20 kg/ha. The findings of the present experiment clearly indicated a great prospect of nutrient combination of N100P10K60S20 kg/ha on the growth and yield of fibre production on the variety BJRI kenaf-4.

Abstract: Phytosanitary measures are management techniques used to prevent unintentional movement of insect pests during timber processing and handling. In this study, the level of awareness on phytosanitary measures used for insect pest control during timber harvesting and post harvesting operations were assessed in Osun, Oyo and Lagos states in Nigeria. Questionnaires (331) were administered to plank marketers, saw mill workers, plant quarantine service workers, forestry officials and tree loggers in the three states. Information on knowledge about phytosanitary measures, pest control and perceptions towards pest infestation was elicited. Data were analysed using descriptive statistics, chi square, and logit regression analysis. The respondents (80.0%) noticed pest infestation in their timber/planks before selling and 93.3% claimed that there were no regulatory bodies in charge of pest management in the forestry sector. The plank marketers used chemical (34.2%) and biological treatments (0.8%) for pest control while saw mill workers used chemical method (42.3%) and painting (4.9%). Logit regression analysis showed that awareness on phytosanitary measures had a positive impact on the willingness of the respondents to adopt the use of phytosanitary measures with an odd ratio of 13.50. Insect pest infestation resulted in reduced income and poor quality timber products. There is, therefore, a need for concerted efforts to generate interest in insect pest control using phytosanitary measures.

Abstract: Chimpanzees (Pan troglodytes ellioti) in ethno-primatological practices among the indigenous people and the implications for biodiversity conservation in the Kimbi-Fungom National Park (K-FNP) and Kom-Wum Forest Reserve (K-WFR), was undertaken to investigate indigenous people perceptions of human-chimpanzee interactions and the effects on wildlife sustainability and biodiversity conservation. Data collections were obtained with the help of interviewer-administered questionnaire, informal interview using unstructured script, palaces/markets gathering discussion and direct field observations of trade. Surveys were carried out in twenty two villages purposefully selected based on their locations and human activities within the proximity of the park and reserve. A total of 288 interviewers were completed during the study. Most of the respondents 94%, 72% and 98% reported that chimpanzee’s body parts/meats are used for medicinal value, rituals and as food in special occasion respectively. About 36 diseases/conditions were randomly reported to be treated by 22 different chimpanzee’s body parts/meat. The usual price of a matured chimpanzee was reported to be in between 75,000-250,000 francs.cfa. Equally, the unsustainable hunting of chimpanzees for body parts/meat was explored to be cause by loss of traditional taboos and totemic beliefs, influx of new cultural practices from Nigeria and within, poverty increment that hinders modern health assurance couple with the fact that protective laws are both less well known and less appreciated. As such, it is imperative that strategies should be put in place to effectively get rid of human activities that negatively impact on biodiversity conservation of chimpanzees in the vicinity of the park and reserve.

Abstract: A field experiment was conducted to evaluate efficacy of pre-emergence herbicides against major weeds in maize at Bako during the main rainy season of 2016/17. The trial was laid out in randomized complete block design (RCBD) with three replication, and consisted of five treatments including pre-emergence application of Lunar 537.5 SE at 3L/ha, Venus 500 SC at 6L/ha and Prima gram dual Gold 660sc at 3 L/ha, and two times hand weeding at 25 and 40 DAS and weedy check for comparison. Application treatments boosted maize grain yield over weedy check plots there by reducing weed infestation. Analysis of variance showed statistically significance difference (P < 0.01) for total weed density (m-2) and dry weight (gm. -2). Significantly the minimum density (8.5 m-2) was observed in plots treated two times hand weeding which was statistically similar with evaluated herbicides. In contrary, the highest (39.1 m-2) was observed in weedy check plots. All the herbicide treatments provided significant control of weeds causing significant reduction in density of target weed flora and also significantly improved the grain yield in comparison with the weedy check. However, no crop injury was observed in any of the herbicide treatments. The maximum grain yield (57.57 qt ha-1) was obtained from Lunar 537.5 SE at 3L/ha followed by two times hand weeding (57.08 qt ha-1) and Venus 500 SC at 6L/ha (54.03 qt ha-1) having the yield advantage of 67.92, 67.64 and 65.82 respectively, whereas; the minimum (18.47 qt ha-1) was from weedy check plots. In general application pre-emergence herbicides effectively control weeds in maize and reduce yield losses. Thus, the newly tested pre-emergence herbicides (Lunar 537.5 SE at 3L/ha and Venus 500 SC at 6L/ha) alone could be option to major weeds and increase maize grain yield.
