143 figs infestation study (eggs)

 

 

 

According to the following plan: study purposes and conditions, eggs volumetry, eggs implantation, ovipositions volumetry, ostiolar regions examination (detailed results).

 

STUDY PURPOSES AND CONDITIONS

 

During the summer of 2021, I decided to examine with a stereomicroscope the ostiolar region of a large number of immature figs infested by Silba adipata McAlpine (figs from my old fig trees having reached the stage of abscission). Fig trees: biferous variety 'Grise de la Saint-Jean', uniferous variety 'Bellone', uniferous variety 'Col de Dame Noire'.

So, for two months (July and August). I collected the figs on the ground by performing a daily inspection under the fig trees. The infested figs therefore did not remain on the ground for more than one day, knowing that some days there were no figs to collect. I also picked up some infested figs from the tree for examination, that instead of falling had reached maturity (varieties 'Grise de la Saint-Jean' and 'Col de Dame Noire').

My objective was to consolidate the observations made over the course of the previous six years, by studying eggs volumetry and eggs physical distribution in figs, and trying to deduce the number of ovipositions per fig, the number of eggs per oviposition, and the eggs physical distribution during an oviposition.

Moreover, I had observed in previous years in the infested figs collection boxes that the larvae still inside the fig often use the exit hole drilled by a larva having previously left the fig. I had also noted larvae death (which could be quite frequent) in the fig central cavity and in the galleries dug in the whitish parenchyma, as well as, on a more exceptional basis, on the epidermis, under the ostiolar scales, and in the ostiolar canal. I therefore set myself as another objective to study the correlation between the number of larvae exit holes carried by a fig and the number of eggs laid by Silba adipata McAlpine inside it.

So, for each of the infested figs, I carried out the following operations: rmeasurement of the diameter with a Vernier caliper; recording of the larvae exit holes number; ostiolar scales and ostiolar canal examination with the stereomicroscope.

Total figs examined: 163, divided into 22 of the uniferous Bellone variety, 88 of the biferous variety 'Grise de la Saint-Jean' (second crop), and 53 of the uniferous variety 'Col de Dame Noire'.

Despite the care I took in examining the ostiolar scales and the ostiolar canal, for 20 fig, I could not find any empty egg envelope, or I found a number less than the number of larvae exit holes. This brings the number of figs with an exploitable examination result to 143. This is divided into 20 of the 'Bellone variety', 77 of the biferous variety 'Grise de la Saint-Jean' (second crop), and 46 of the 'Col de Dame Noire' variety.

I found no unhatched eggs when examining the ostiolar region of all the figs, only empty eggs envelopes.

(explanation of the hole size: the larva is 9 times larger when it leaves the fig than at birth).

 

I provide below the analyzes established from the detailed results of the infested figs examinations. These results are reported at the end of this chapter, for reasons of reading clarity.

 

EGGS VOLUMETRY

 

Total laid eggs (143 figs): 356. Average: 2.5 eggs per fig.

Number of eggs deposited in the figs - 1 egg: 24% of the figs (34); 2 eggs: 38% (54 figs); 3 eggs: 18% (26 figs); 4 eggs: 10% (15 figs); 5 eggs: 8% (11 figs); more than 5 eggs: 2% (3 figs).

The above count shows that 98% of the examined figs contain 1 to 5 eggs, and that 80% of the examined figs contain 1 to 3 eggs.

EGGS IMPLANTATION

 

DEFINITIONS

I call "first level" ostiolar scales the scales which are located on the surface of the fig (these are the highest ostiolar scales). The first level scales can slightly overlap at the tip. They are thick, leathery, and often reddish in color (entirely or at the edges).

And I call "second level" ostiolar scales those which are just below the first level scales. Largely or completely covered by the first level ostiolar scales, they are quite tough or quite tender depending on the variety. Their color is generally greenish, partially reddish for certain varieties.

Below the second level ostiolar scales are thin scales, softer than the previous ones, light green in color. Generally horizontal, they precede the ostiolar canal scales (vertical and whitish). They are never the subject of an egg deposit.

 

PERCENTAGES OF INFESTED FIGS BY TYPES OF USED SCALES

83% of the 143 figs examined (118) harbor eggs only under first level ostiolar scales; 8% (12 figs) harbor eggs only under second level ostiolar scales; 7% (10 figs) harbor eggs under first and second level ostiolar scales; 2% (3 figs) harbor eggs in the ostiolar canal alone.

Note: for 2 figs, a single empty egg envelope was found on the epidermis, near a first level ostiolar scale (displacement during the larva birth?). They were counted with figs harboring eggs only under first level ostiolar scales.

These results confirm my regular observations of much lesser occurrence of ovipositions under second level scales, and rare ovipositions in the ostiolar canal.

 

PERCENTAGES OF INFESTED FIGS BY NUMBERS OF USED SCALES

64% of the 143 figs examined (91) harbor eggs under a single ostiolar scale; 28% (40 figs) harbor eggs under 2 ostiolar scales; 6% (9 figs) harbor eggs under three ostiolar scales; 2% (3 figs) harbor eggs in the ostiolar canal alone.

Note: in the examined batch, none of the figs simultaneously harbor eggs in the ostiolar canal and under one or more ostiolar scales. But I have already observed these cases.

These results confirm my regular observations of low occurrence of the eggs distribution under 3 ostiolar scales, and absence of eggs dissemination under more than 3 ostiolar scales, for figs containing a maximum of 5 eggs.

 

EGGS DISSEMINATION ACCORDING TO THE NUMBER OF USED OSTIOLAR SCALES

Note: the numbers in parentheses after the number of figs indicate the eggs distribution under the ostiolar scales. So (2.3) means 2 eggs under an ostiolar scale and 3 eggs under another ostiolar scale (5 eggs distributed under 2 ostiolar scales).

When a single ostiolar scale covers all the eggs (64% of figs examined; 91 figs), I count: 1 egg in 37% of cases (34 figs); 2 eggs in 40% of cases (36 figs); 3 eggs in 14% of cases (13 figs); 4 eggs in 3% of cases (3 figs); 5 eggs in 6% of cases (5 figs).

When all the eggs are disseminated under two ostiolar scales (28% of 143 figs examined; 40 figs), I count: 2 eggs in 38% of cases - 15 figs (1.1); 3 eggs in 30% of cases - 12 figs (1.2); 4 eggs in 23% of cases - 9 figs, including 7 figs (2.2) and 2 figs (1.3); 5 eggs in 7% of cases - 3 figs, including 2 figs (1.4) and 1 fig (2.3); 7 eggs in 2% of cases - 1 fig (2.5).

When all the eggs are disseminated under three ostiolar scales (6% of 143 figs examined; 9 figs), I count: 3 eggs in 11% of cases - 1 fig (1.1.1); 4 eggs in 33% of cases - 3 figs (1.1.2); 5 eggs in 33% of cases - 3 figs, including 2 figs (1.2.2) and 1 fig (1.1.3); 6 eggs in 22% of cases - 2 figs (1.2.3).

When the eggs are located in the ostiolar canal (2% of 143 figs examined; 3 figs), I count: 1 egg in the case of a fig, and 2 eggs in the case of 2 figs.

Particular observation: case of figs containing 5 eggs.

I note that the figs containing 5 eggs grouped under a single ostiolar scale, 5 in number, represent 3.5% of the total of the examined batch (143 figs). And that the figs containing 5 eggs distributed under 2 or 3 ostiolar scales, 6 in number, represent 4.2% of the total of the examined batch. Figs containing 5 eggs, 11 in number, representing 7.7%, rounded to 8%, of the total of the examined batch (which is consistent with the volumetry indicated in the previous subchapter for this type of figs).

OVIPOSITIONS VOLUMETRY

 

When examining the ostiolar regions (detailed results provided at the end of the chapter), I counted the ovipositions for each of the figs, using a method that I developed (based on the number of eggs contained in the fig, and on their implantation under the ostiolar scales or in the ostiolar canal). This method is imperfect, but allows a plausible approximation of the number of ovipositions to which a fig has been subjected, in the form of ranges in a certain number of cases.

Number of ovipositions per fig - 1 oviposition: 65% (93 figs); 2 ovipositions: 0.7% (1 fig); 1 to 2 ovipositions: 28% (40 figs); 1 to 3 ovipositions: 5% (7 figs); 2 to 3 ovipositions: 1.4% (2 figs).

Note: among the 93 figs (65% of the total of the examined figs batch) having been the subject of only one oviposition, 33 (23% of the total of the examined batch) contained only one egg. For the others (60, i.e. 42% of the total of the examined batch), the estimate of a single oviposition results from the counting method (all the eggs under an ostiolar scale counted as a single oviposition). Knowing that for scales covering 2 or 3 eggs, we can estimate that this is almost always the case (eggs coming from a single female), and that for scales housing 4 or 5 eggs, the margin of error is low because they are only observed in 6% of the figs in the examined batch.

The study of the correlation between the number of larvae exit holes carried by the figs and the number of eggs deposited in them is the subject of another chapter, the publication of which is to come.
