In the intense male–male competition for females, males often develop alternative reproductive tactics to achieve successful reproduction through unconventional means. These tactics often arise from their own condition and surroundings.
, such as the sex ratio, as a predictor of the intensity of male–male competition. The researchers discovered that in the case of two-spotted spider mites when the sex ratio of the maternal generation is biased toward females, their sons display sneaking tactics and often show early pre-mating guarding.
When confronted with a female-biased sex ratio, mothers produce more sons than usual, resulting in more males in the next generation and increased intensity of male–male competition. The male mites mount on the back of the females in the stage just before adulthood as a pre-mating guard. There are two types of males:"fighters," who guard females by fighting, and"sneakers," who do not behave as males and secure a position advantageous for mating without fighting. However, sneakers cannot take over females that are already guarded. Therefore, in situations with more rival males, sneakers will begin pre-mating guarding at an earlier stage.
