“…It seems that the effect of larval experience on adult preferences (i.e., preimaginal conditioning) is limited in holometabolous insects (Harrison, 1987; Lu & Logan, 1994; Rojas & Watt, 1999; Barron, 2001; Hora et al., 2005). Adult fecundity, however, is to a large extent affected by host plant quality (Awmack & Leather, 2002), and the data presented here showed that S. myriacanthum is a poor host for female feeding and reproductive development (López‐Carretero et al., 2005). Females fed with S. myriacanthum ate leaves during fewer days than control females in the 40‐day feeding experiments, and remained motionless until the end of the experiment (A Eben & A López‐Carretero, unpubl.).…”

“…Solanum chrysotrichum , S. diversifolium , S. lanceolatum , S. ochraceoferrigineum , S. saponeceum , and S. torvum have been described as host plants for L. undecimlineata in Mesoamerica (Hsiao, 1986, 1988; Cañas et al., 2002; O’Neil et al., 2005). Solanum lanceolatum and S. ochraceoferrigineum are common hosts in Mexico (Jacques, 1988; López‐Carretero et al., 2005).…”

“…In the centre of the state of Veracruz, in eastern Mexico, L. undecimlineata feeds exclusively on Solanum lanceolatum L., even though Solanum myriacanthum Dunal grows often sympatrically to S. lanceolatum (López‐Carretero et al., 2005). Solanum lanceolatum is an invasive perennial shrub growing mainly in pastures.…”

The relationship between preference and performance was studied under laboratory conditions for larvae and adult females of Leptinotarsa undecimlineata (Stål) (Coleoptera: Chrysomelidae). Leptinotarsa undecimlineata feeds exclusively on Solanum lanceolatum L. (Solanaceae) in the centre of Veracruz, Mexico. A common sympatric species, Solanum myriacanthum Dunal, is not used as host. We conducted a series of laboratory experiments to detect reasons for the exclusive use of one host plant. Leptinotarsa undecimlineata larvae were reared under laboratory conditions on both plant species, Solanum lanceolatum and S. myriacanthum . Length of larval stages, pupal weight, and percent adult eclosion were compared, and larval preference for both Solanum species was tested. Upon eclosion, adult females were exposed to each of the plants, and the effect of larval diet on adult preference was determined. Oviposition on both Solanum species was observed in no-choice tests. Larvae showed no significant preferences for either plant species. Pupal weight, however, was significantly higher on S. lanceolatum . Female beetles significantly preferred S. lanceolatum leaves, and no effect of preimaginal conditioning was found. Females reproduced in lower numbers after feeding on S. myriacanthum , oviposition initiated later, and females laid fewer eggs than females fed with S. lanceolatum . No female accepted S. myriacanthum for oviposition. Results obtained suggest that the potential host breadth of L. undecimlineata is broader in larvae than in female beetles.

“…From an agroeconomic point of view, decreased reproduction (lower number of laid eggs and lower fertility and fecundity) is one the most important insecticidal effects, and malfunctions and malformations of the reproductive system can be induced by glycoalkaloids. The disruptive toxic effects of Solanaceae plants on insect reproductive systems have been shown; insects reared on non-host plant species revealed diminished production of oocytes and increased reabsorption of formed oocytes, which inhibits the maturation of eggs [ 61 ]. These authors postulate that the glycoalkaloids present in the leafs of non-host plant species may interact with the endocrine system of pests, especially altering juvenile hormone-like activity, similarly to other glycoalkaloids [ 62 ], thus disturbing insect development.…”

Only a small percentage of insect species are pests. However, pest species cause significant losses in agricultural and forest crops, and many are vectors of diseases. Currently, many scientists are focused on developing new tools to control insect populations, including secondary plant metabolites, e.g., alkaloids, glycoalkaloids, terpenoids, organic acids and alcohols, which show promise for use in plant protection. These compounds can affect insects at all levels of biological organization, but their action generally disturbs cellular and physiological processes, e.g., by altering redox balance, hormonal regulation, neuronal signalization or reproduction in exposed individuals. Secondary plant metabolites cause toxic effects that can be observed at both lethal and sublethal levels, but the most important effect is repellence. Plants from the Solanaceae family, which contains numerous economically and ecologically important species, produce various substances that affect insects belonging to most orders, particularly herbivorous insects and other pests. Many compounds possess insecticidal properties, but they are also classified as molluscides, acaricides, nematocides, fungicides and bactericides. In this paper, we present data on the sublethal and lethal toxicity caused by pure metabolites and crude extracts obtained from Solanaceae plants. Pure substances as well as water and/or alcohol extracts cause lethal and sublethal effects in insects, which is important from the economical point of view. We discuss the results of our study and their relevance to plant protection and management.

“…This process is proposed to be an adaptive mechanism to optimize fitness in hostile environments such as parasitic attack or lack of mates, food or host substrate (Bell & Bohm, 1975; Ohgushi, 1996; Rosenheim et al. , 2000; Kotaki, 2003; Wang & Horng, 2004; Lopez‐Carretero et al. , 2005; Barrett et al.…”

Diet and social conditions during sexual maturation have unpredictable influences on female life history trade‐offs

The trade‐off between gametes and soma is central to life history evolution. Oosorption has been proposed as a mechanism by which females can redirect nutrients invested in oocytes into survival when conditions for reproduction are poor. Although positive correlations between oocyte degradation and lifespan have been documented in oviparous insects, the adaptive significance of this process in species with more complex reproductive biology has not been explored. Further, environmental condition is a multivariate state, and combinations of environmental stresses may interact in unpredictable ways. Previous work on the ovoviviparous cockroach, Nauphoeta cinerea, revealed that females manipulated to mate late relative to sexual maturation experience age‐related loss in fecundity because of loss of viable oocytes via apoptosis. This loss in fecundity is correlated with a reduction in female mate choice. Food deprivation while mating is delayed further increases levels of oocyte apoptosis, but the relationship between starvation‐induced apoptosis and life history are unknown. To investigate this, virgin females were either fed or starved from eclosion until provided with a mate at a time known to be suboptimal for fertility. Following mating, females were fed for the duration of their lifespan. We measured lifetime reproductive performance. Contrary to predictions, under conditions of delayed mating opportunity, starved females had greater fecundity, gave birth to more high‐quality offspring and had increased longevity compared with that of fed females. We suggest that understanding proximal mechanisms underlying life history trade‐offs, including the function of oocyte apoptosis, and how these mechanisms respond to varied environmental conditions is critical.
