Metarhizium bioassay 4

On 01/09/12 four soil samples from four different GMF sinks (Ada, Oka, Fujita 1&2) were taken and placed into glass jars containing healthy CRB larvae to see if they would get infected by the GMF growing in the soil. In total, six 1sts, 7 2nds and three 3rds were placed into separate jars. Also, all female beetles that are found in the GMF sinks are now being collected and brought in to test in this experiment.

Ada jar numbers:

0026: 1st instar

0036: 2nd instar

0033: 3rd instar

0037: 1st instar

Oka jar numbers: 

0038: 1st

0024: 2nd

0039: 3rd

0678: 2nd

Fujita 1:

0040: 1st

0031: 2nd

0041: 3rd

0682: 1st

Fujita 2:

0025:1st

0032: 2nd

0043: 2nd

0028: 2nd

Adult CRB jars:

1029

0045

One week later, the jars were checked.

Ada

0026: 1st was dead and disintegrated

0026: the 2nd was near death, not moving and turning hard

0033: 3rd still alive and active, but with black fluid coming out of its mouth

0037: 1st dead and green

Oka: 0038 alive 

0024: alive

0678: alive

0039: alive with black fluid coming from mouth

F1

0040: dead with green/white coloring

On 01/25/12 all jars were checked again and all the larvae were dead and covered with green hyphae. The adult beetles were still alive.
