Background: Fungal endophytes are heterotrophic microorganisms that occur inside plant tissues, with some showing adverse effects against insects, nematodes and plant pathogens. Initiatives are underway at the International Center of Insect Physiology and Ecology (ICIPE) to use these endophytes as a novel strategy for control of Liriomyza leafminer. Objective: The objective of this study was therefore to search for fungal endophytes from the Liriomyza major host plants that could be used in the management of this invasive insect pest. Materials and Methods: Bioprospecting was undertaken to isolate fungal endophytes from Phaseolus vulgaris and Vicia faba seeds collected from different local and super markets in Kenya. Fungal endophytes were isolated through seeds surface sterilization and characterized using morphological and molecular techniques. Fungal occurrence was analyzed using analysis of variance while Chi-square tests were performed to compare the various endophytes species occurring in the two host seeds. Results: Five fungal isolates were isolated from both P. vulgaris and V. faba seeds with no significant differences in their occurrence. However, there was significant difference between the endophyte species occurring in V. faba compared to P. vulgaris seeds (p<0.0001). Isolated fungi included Beauveria bassiana, Phialemonium sp., Phanerochaete chrysosporium and Metarhizium anisopliae. Beauveria bassiana ICIPE 693 occurred in all the V. faba seeds (100%) but not in P. vulgaris seeds. Similarly, P. chrysosporium had 66.7% occurrence in V. faba but absent in P. vulgaris seeds. The prevalence of Phialemonium sp. (55%) was only recorded in P. vulgaris, while that of M. anisopliae was recorded in both P. vulgaris and V. faba seeds with 55.4 and 70.8% occurrence, respectively. Conclusion: Fungal endophyte species occurrence in V. faba differed from P. vulgaris seeds. The characterization of these bean seed-born endophytes will not only create awareness but also facilitate studies on the role of these fungi in pest management strategies. The outcome of this study will stimulate further studies on the possible roles of these fungi in inhibiting the growth of artificially inoculated endophytes, assessing their pathogenicity and virulence effects on different sucking arthropod pests and evaluating the nutritional value of the seeds containing these endophytes.

Background: Studies was carried out to determine whether there is interaction effect between sugarcane varieties and stratified nurseries to the percentage of plantlet viability and its height. Materials and Methods: This study was conducted in Perning and Mojokerto from June-August, 2015. The study method using a completely randomized factorial design consisting of two factors, namely the variety including Bululawang, VMC 76-16, Cokro and clone Columbia-2 while, the second factor is the stratified nurseries including Grandma’s Plantlet Nursery (GPN), Mother’s Plantlet Nursery (MPN) and Flat Plantlet Nursery (FPN). Thus, there were 12 treatment combinations and repeated three times. The bud-chips were planted in the trays with the size 4 cm during 3 months, every month data was collected for percentage of plantlet viability and its height. Data analyzed was done by Minitab 16 for ANOVA and LSD 5%. Results: The results showed that there is not interaction between stratified nursery and variety to the percentage of plantlet viability and plantlet height. Stratified nursery shows that GPN significantly produces percentage of plantlet viability and its height greater at Month After Sowing (MAS) while, MPN gives plantlet higher at the last 3 MAS. Bululawang gives percentage of plantlet viability significantly greater at 1 MAS only while, VMC 76-16 shows the plantlet higher at 1 and 2 MAS. Four varieties planted show the same response at 3 MAS to variables used. That means their responses to percentage of viability and plantlet height are the same. Based on this study, the use of single bud (bud-chip) technique based SOP able to produce percentage viability until 90%. Conclusion: It can be concluded that Columbia-2 is a promising introducing clone. On the other hand, superior bud-chips can be produced from both GPN or MPN and able to be used as the right solution.
