“…In phytophagous insects, the most commonly reported biotic agent promoting parental care is arthropod predators (e.g. Wood, 1976a;Melber et ul., 1980;Tallamy & Denno, 1981b;Windsor, 1987;Nafus & Schreiner, 1988;Hardi'n & Tallamy, 1992;Kudo et al, 1992;Kudo & Nakahira, 1993). However, in many cases, whether or not the parental care has function(s) other than defence, e.g.…”

I . In the spring, females of the leaf beetle Gonioctena sibirica deposited larvae on the ventral surface of growing young leaves situated on the apical position of shoots of the willow Sulix bakko.2. The parent females remained with the larvae usually on the underside of the basal part of leaves, facing toward the base of shoots. When other arthropods approached, the females temporarily moved towards these intruders, showing aggressive behaviour such as swinging the body or stamping the legs. Many females remained with their larvae until the larvae grew into the final (fourth) instar. No female produced an additional brood in the field.3. Broods from which parent females were experimentally removed suffered higher mortality than those in which females were left intact. Arthropods such as spiders and ants were observed preying on the larvae. In contrast, the survivorship of broods from which females were removed and intruders were excluded with a sticky substance applied to the base of twigs was not different from thlat of control broods. These results demonstrate that the main mortality factor of offspring is pedestrian arthropod predators and females physically repel the predators. 4.Potentially alternative reproductive strategies, such as producing a large number of offspring by iteroparity and/or larger brood(s) with less or no care, seem to be inhibited in G.si6irica by larval dependence on growing young leaves which are temporally limited and by ovoviviparity which may have limited brood size.

“…A alta taxa de predação que pode ocorrer sem a proteção materna parece ser o fator determinante do cuidado maternal em A. sepulcralis, assim como ocorre na grande maioria das espécies subsociais (Tallamy & Denno 1981, Tallamy 1984, Kudo et al 1992, 1995, Kudo & Nakahira 1993, Mappes & Kaitala 1994, 1996, Kudo 1996. Essa alta predação pode ser explicada pelo fato de que insetos que apresentam agregação de ovos ou ninfas aumentam a probabilidade de serem atacados por predadores, uma vez que estes exercem maior atratividade em relação àqueles solitários, que representam fontes de alimento isoladas (Tallamy 1984, Mappes et al 1995.…”

Efficiency of the Maternal Care of Antiteuchus sepulcralis (Fabricius) (Hemiptera: Pentatomidae) Against Natural Enemies of the Egg Stage ABSTRACT-This study was carried out on trees of the host plant Hibiscus pernambucensis Arruda (Malvaceae), to evaluate the potencial benefits gained from maternal care in Antiteuchus sepulcralis (Fabricius). Three kinds of sleeve cages were used: with no access to natural enemies (=control); with access only to parasitoids, and with access to all natural enemies (predators and parasitoids). A fourth treatment consisted of complete exposure, with no cage. For all treatments, there was a condition in which the egg mass was protected by the mother and one in which the mother was removed. This experiment was repeated 15 times on different dates. Egg masses were also collected in the field to assess the parasitism rates under natural conditions. The predation rate in unprotected egg masses was 100% in less than 24h, whereas no egg was fed upon when the mother was present. Parasitism rates in the sleeve cage treatments, caused exclusively by Phanurospis semiflaviventris Girault (Hymenoptera: Scelionidae), were 41.6% and 69.5% in egg masses protected and not protected by the mother, respectively. Under natural conditions, parasitism rates were 66.4%, 20.1%, and 62.2% in the periods of December/96-March/97, August-October/97, and November/97-February/98, respectively. Eggs located on the outside edge of the egg mass experienced higher levels of parasitism than the internal ones. These results show that the female defense is highly effective against predators, but not so effective against the parasitoid P. semiflaviventris. The adaptive value of the maternal care in A. sepulcralis (trade-off between benefits and costs) as a strategy for offspring survival is discussed.

“…Parental care in insects is rare, possibly because in most species parents can do little to protect or nurture the offspring (Zeh & Smith 1985;Tallamy & Wood 1986). Exceptions include species in which eggs or young face particularly harsh environments or high predation pressures, because in these species parents can improve offspring survival substantially by keeping environmental conditions at an optimal level for the development of the offspring (Smith 1976;Tyndale-Biscoe 1984;Wyatt 1986;Favila 1993;Halffter et al 1996), protecting offspring against food competitors (Tyndale-Biscoe 1984;Wyatt 1986;Halffter et al 1996), or protecting them against predators (Tallamy & Denno 1981;Nafus & Schreiner 1988;Kudô et al 1989;Scott 1990;Kudô & Nakahira 1993;Kudô et al 1995;Kudô & Ishibashi 1996) or parasitoids (Ralston 1977). The distribution of parental care among arthropods is such that in most species care is provided by the female alone, followed by biparental care and, finally, paternal care is the least frequent form of care (Zeh & Smith 1985;Clutton-Brock 1991).…”
