At the end of the incubation period order mebendazole online hiv infection using condom, pellets from each pin were transferred to 1 ml of sterile deionised water containing 0 discount 100mg mebendazole with visa antiviral eye drops. In experiment 3 order mebendazole in united states online hiv infection using condom, the ability of the fungal pellets to form a sporulating mycelial mat in the continuous presence of the adjuvants was assessed through two ways of pellet treat- ment. In the rst method, 5 ml of the biomass was transferred along with the spent medium to 15-ml glass vials and each adjuvant was added separately, swirled and incubated for 30 days by which time a sporulating mycelial mat (ca. In the second method, the adjuvant solutions were prepared separately, and the pellets obtained from 10 ml of shake-ask culture of H. In both methods, at the end of the incubation period, the 20-mm-diameter mycelial mat was transferred to 10 ml of 0. Growth and conidiation of mycelial pellets on excised parts of the coconut palm The following parts of the coconut palm (Purseglove 1972) were tested for their suitability as substrates for germination and conidiation of H. These plant parts were excised into 2 small pieces (2 9 2cm for at parts, or 5 cm long for cylindrical parts) or used as such (only tepals) with each piece serving as a replicate. Observations were recorded for growth and coni- diation of mycelial pellets frequently (at least three times in a 24-h period) for up to 96 h. Effect of simulated sunlight on the conidiation of Hirsutella thompsonii Mycelial beads of H. Pellets treated with Diseases of Mites and Ticks 173 only sterile deionised water served as control. A 1100-W air-cooled xenon arc lamp gave an 2 output spectrum closely resembling sunlight in a total exposure area of 560 cm inside the simulator chamber. After sunlight treatment, the lids were replaced and two sub-sets of three Petri dishes each for the adjuvants and control were further incubated at alternating light dark regime (12:12 h) and total darkness, respectively, for 48 h at room temperature. For non-irradiated control, a similar protocol was followed with Petri dishes enclosed in black paper while inside the simulator, but other incubation conditions remained the same. At the end of the incubation period, all pellets from each Petri dish were transferred to 5 ml of sterile deionised water containing 0. Pathogenicity of adjuvant-treated pellets Before the eld trial, the three best adjuvants were tested for their effect on the patho- genicity of H. Chips (20 mm diameter) were sliced from beneath the perianth of young, freshly harvested 2 nutlets showing very high mite infestation ([20 live adult mites/mm ) after carefully removing the bracts. The pellets treated as in the plant parts study were rst allowed to germinate for 24 h and then transferred to the surface of the chip contained in the centre of a clean 200-mm glass Petri dish, at a rate of ve pellets per chip. The Petri dishes arranged in this manner were then closed and kept at room temperature with a 12-h photoperiod. The formulation process and ingredients, including the carrier and the additives (or formulants) incorporated into the nal product were the same as the original product. A block of 84 palms (7 rows 9 12 palms) at the centre of the grove was selected, out of which the rst three rows were used as a set for the fungal treatment and the last two as a set for the chemical and control treatments, with a buffer of two untreated rows in between these sub-blocks. The individual treatments were randomised 12 times each within their respective sets. After harvesting the mature coconuts from each experimental palm, the bunches were numbered by considering the fully open inorescence as the rst bunch and the preceding older bunches sequentially as second, third, etc. The second and third bunches were tagged by tying insulated electric wire of the best-visible colours, viz. For obtaining pre-treatment population data, the third nutlet from the bottom of the bunch was sampled from the fourth and fth bunches. Following the pre- treatment sampling, all the bunches were treated with the specic spray uid (2 l/palm) using a portable, lightweight, hand-compression sprayer (3. All the spray uids were prepared in plain water and applied thrice as sprays at fortnightly intervals during early mornings. The post-treatment population count of the mite was recorded in all the palms 6 weeks after the rst round of treatment. Population counts were made on two nuts, one each from both the tagged bunches, in the same way as pre-treatment analysis. Finally, during the pre- harvest stage, both the tagged bunches were cut off entirely from the palm and brought down for grading. The nuts were separated from the short peduncles from each bunch separately and were graded individually based on the damage caused by the mite. Data analysis All laboratory experiments were performed twice and the eld trial once. For the labo- ratory experiments, the results from only one trial are presented because a similar trend was observed between the trials with homogeneity of variances determined with Bartlett s test. Prior to analysis, the data from conidial counts were subjected to log(x)-transformation to improve homogeneity of variances. Data on colony counts on the lter paper and pathogenicitypwere square-root- p p transformed x. The pre-treatment x and post-treatment x 0:5 data from the eld trial were also subjected to square-root transformation. Diseases of Mites and Ticks 175 Results Effect of adjuvants on the growth characteristics of Hirsutella thompsonii The number of fungal colonies formed on the lter paper by H. Hyphal development and extension occurred in less than 24 h only in glycerol treatment. In other treatments, it took anywhere between 24 and 48 h, except in the case of gelatine and nutrient broth, both of which took longer. Several test adjuvants were able to take sporulation levels much higher than the untreated control (F9,20 = 15. Gelatine was the least effective among all the treatments with the lowest 4 numbers of conidia (2. In terms of conidia density generated on a 20-mm-diameter mycelial mat, the treatments varied signicantly. In the second method, wherein pellets were added to the adjuvant solution (F9,20 = 46. Growth and conidiation of mycelial pellets on excised parts of the coconut palm Conidiation of adjuvant-treated mycelial pellets occurred on various parts of the coconut palm but the progress of growth and conidiation was not uniform on all (Table 3). The progress of fresh fungal growth out of the pellets was the best on the nut surface or exocarp (green portion of tender nut). An unexpected shrinkage of the mycelial pellets was observed on the short peduncle as well as on the adaxial and abaxial surfaces of the leaet. Effect of simulated sunlight on the conidiation of Hirsutella thompsonii Irradiance with simulated sunlight for 1 h resulted in reduced conidiogenesis by H. Better conidiation was observed under alternating light dark regime than under total darkness in all the treatments (F3,32 = 39. The three adjuvants shielded the pellets from adverse sunlight to certain extent and helped retain enough moisture to be able to undergo conidiogenesis successfully (F3,32 = 19. Pathogenicity of adjuvant-treated pellets Prior to eld-testing of the fungus, the adjuvant-treated pellets were tested for pathoge- nicity towards the coconut mite. Glycerol-treated pellets were the most effective in terms of the mortality caused, a 16. Field trial 2 The pre-treatment counts of live mites per mm of the nut surface just below the perianth ranged from 6.
