Earth Venus resonances - gap simulation

Similar to the famous Kirkwood gaps there must be positions in the solar system between Venus' en Earths orbit where asteroids lay be spare .  
The sim hereby puts 300 particles into circular orbit between Venus and Earth , originally at 0 Inclination .  
How do they evolve ?

The system above seems to be full of resonances as can be seen in the animation hereunder , which shows the eccentricity build up during almost 1000 years of simulation .
The resonances are weak but can be attributed to either Venus or Earth , in some cases to both .  
The last picture of the animation shows the possible resonances .  
In this picture the resonances to Venus are shown on top , those to Earth at the bottom line .

Not surprisingly also the inclination of the test particles will be influenced by both planets Venus and Earth.  
The animation shows the inclination build up of the test particles .  
Surprisingly there is little indication  of resonances in this graph , but inclination variation  seems to be function of the distance to either planet .

If we plot the LAN evolution of the test partucles between Earth and Venus one gets a plot as shown here :
The longitude of ascending node , which originally was set at random between 0 to 360 evolves quickly te a value near 165 .  I don't know how this value is related to the LAN Venus ( 76) and the value of Earth ( 149) .
