Our aim was to find out whether the change in the gravitational potential of celestial bodies influences the

effectiveness of light trapping of the moths.

Of course, we do not know the number of species in each species from spec. indet. data. However, it is reasonable

to assume that more species can be found from the caught by the light-trap in the field. And even if we take into

account that the same species in the country are not in the same masses, then we can assume that the material

available to us is a realistic picture of the behavior of the majority of the moth (Microlepidoptera) species in

relation to the gravity of the Sun and the Moon.

1.1 Calculation results of the negative and positive gravitational potential of celestial bodies

The gravitational potentials of celestial bodies (Sun or Moon) is given in Figure 1. And the critical elevation

depending on the gravitational potential of the celestial bodies is given in Figure 2.

Figure 1 The gravitational potentials of celestial bodies (Sun or Moon) (μJ/kg)

Note: a = Positive signage of gravity potential (eg + 500 μj/kg) increases the gravitational potential of Earth, thus inhibiting uplift of

insect; b = The gravitational potential of Earth = h * g (µJ/kg). The Earth’s gravitational potential in Budapest is 9.808,52 cm/s

2

(Budó, 1978); c = Negative signage of gravity potential (eg -500 μj/kg) reduces the Earth’s gravitational potential and helps the

growth of insect; d = Resulting gravitational potential (e.g. if the sky’s gravity potential is -500 μJ/kg); e = Critical rise height, here

the resulting gravitational potential is zero; If h < h

0

, the suctioning effect of the celestial body dominates; if h > h

0

, then the Earth’s

inhibitory effect prevails

Figure 2 The critical elevation depending on the gravitational potential of the celestial bodies

Note: The critical elevation of h

0

means that the sucking effect of celestial bodies is equal with the Earth’s attractive effect
