“…Females of C. maculatus and Z. subfasciatus attach their eggs to the surface of the seeds using a gelatinous glue-like material (Shazali, 1990). On the contrary, females of A. obtectus lay batches of eggs randomly under the seeds (Umeya and Kato, 1970).…”

“…This means that multiple larvae enter the bean through holes that were bored by other larvae (Labeyrie 1960). The larva boring an entrance hole is called a pioneer, and the larvae that enter a bean through the hole bored by the pioneer are called followers (Umeya and Kato 1970). The number of followers is usually higher than the number of pioneers (Labeyrie 1960;Umeya and Kato 1970).…”

Larvae of Acanthoscelides obtectus show two contrasting behaviors when entering a bean. One is pioneer behavior in which a larva enters the bean through an entrance hole made by itself; the other is follower behavior in which a larva enters the bean through an entrance hole made by a pioneer. Previous studies have shown that the number of followers is much greater than that of pioneers. If there is a cost to being a pioneer, and if larvae can choose either of the two strategies, there is a dilemma: to be a pioneer or not. This dilemma is similar to the chicken game because if all larvae avoid choosing the risky pioneer strategy in favor of the follower strategy, none of the larvae can enter a bean, and they will die. In the present study, in order to investigate whether the larvae of A. obtectus are facing a dilemma of entry order, we experimentally measured the cost to pioneers and tested the flexibility of larval entering strategies. Pioneers' costs were measured by entrance success rate, and the flexibility of larval strategies was tested by gauging the proportion of pioneers at various larval densities. The entrance success of pioneers was lower than that of followers, and the proportion of pioneers decreased as the number of competing larvae increased. These results suggest that the Pioneer-Follower interaction in A. obtectus satisfies the conditions for a dilemma game: the larvae of A. obtectus are in a dilemma of entry order.

“…This process consists of "ODP marking" by egg layers and "ODP avoidance" by ODP receivers. It has been reported that eggs of the azuki bean weevil, Callosobruchus chinensis, are uniformly distributed among host azuki beans (Utida 1941;Umeya & Kato 1970). These behavioral characters are adaptive for utilizing stored beans in 2 ways: (1) females can avoid laying eggs on the beans where other individuals have already laid eggs, and (2) females carl deter other females from laying additional eggs on the depositers' host beans.…”

“…Oviposition deterring pheromones (ODPs) are insect-produced substances that deter conspecific females from laying eggs on the site where the pheromone is deposited (Anderson 1988). ODPs are found in about 40 species of 4 different orders, including 3 bruchid species (Umeya & Kato 1970;Oshima et al 1973;Mitchell 1975;Southgate 1979;Anderson 1988). This process consists of "ODP marking" by egg layers and "ODP avoidance" by ODP receivers.…”
