“…Of course insects develop resistance against toxicants, and herbivores are more prone to developing resistance to plant defenses due to natural selection than predatory or parasitoid insects, which are natural enemies of pests [ 54 , 55 ]. The alkaloids present in the bodies of pests may negatively affect their predators [ 56 , 57 ], and this phenomenon may seriously disturb biological control and influence IPM strategies.…”

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.

“…Mixing different control tactics randomly will not necessarily produce better results than a single tactic; in some cases, the combination may trigger antagonistic effects and potentially reduce crop yields and farmer profits (Kogan, 1988(Kogan, , 1998Thomas, 1999;Ehler and Bottrell, 2000;Ehler, 2006). For example, while host-plant resistance and biological control are usually compatible, the morphological, physiological or chemical traits of insect-resistant cultivars may discourage or even cancel out the potentially beneficial effects of a natural enemy (Gould et al, 1991;Hare, 1992;Johnson and Gould, 1992;Thomas, 1999;Tandon, 2001;Kennedy and Gould, 2007). The outcome of the interaction will depend on the specific relationship between the pests and their natural enemies and how the resistant plants affect both.…”

“…In extreme cases of antagonism (i.e. disruptive relationships), plant resistance could affect natural enemies more than pests and therefore reduce the effectiveness of biological control (Tandon, 2001). Table 2 provides examples of possible outcomes when two pest control tactics, A and B, are combined.…”

Hailed as the single most important paper published on crop protection in the 20th century, Stern et al. in 1959 formed the conceptual basis for modern integrated pest management (IPM) worldwide. The ecological foundation for IPM envisioned by its authors is as valid today as in 1959. However, adoption by developing country farmers has been low and its advances short-lived. The present paper examines the concept of integration in IPM and criteria for determining whether its control tactics have been integrated harmoniously. The effects of local and regional landscape patterns on pests and on the design of IPM are reviewed, arguing that the agroecosystem must be understood and managed as a living system with the goal of enhancing and conserving agrobiodiversity and keeping ecosystem services intact. Key to IPM adoption is convincing farmers to integrate non-chemical alternatives (e.g. biological control, plant diversification) as primary management components and to apply pesticides judiciously and only after non-chemical components fail to manage pests effectively. Research, extension and policy changes are identified to increase the efficiency, adoption and sustainability of IPM on resource-limited farms. The over-arching challenge is devising communication and support systems that allow resource-limited farmers to try, adopt and sustain IPM that enhances yields and profits in light of the many uncertainties and challenges. Use of information technology, media development, crowdsourcing and rural sociology is advocated to connect farmers to the technical sources required to enhance yields and profits and reduce risks to them, the farming community and the environment.

“…Some resistance mechanisms that protect plants from herbivorous insects may harm or repel beneficial predatory insects, making HPR and biological control partially incompatible [ 7 , 8 ]. For example, plant resistance may have an adverse impact on natural enemies when toxic secondary plant compounds are passed on to natural enemies through the pest, resulting in prey-mediated indirect effects [ 9 , 10 ].…”

“…The development of P. absoluta -resistant tomato cultivars is a sustainable alternative to insecticide application [ 1 , 9 , 24 , 25 ]. It is important, however, to make sure that the employment of resistant crops is compatible with the activity of natural enemies in the system [ 26 ]; there is ample evidence for the adverse effects of resistant genotypes on natural enemies [ 8 , 27 ]. Particularly susceptible to such negative effects of resistant crops are omnivorous predators that feed on plant materials in addition to prey [ 28 ].…”

Complex interactions between host plant resistance (HPR) and biological control agents, particularly omnivorous predators, can shape the outcome of an integrated pest management (IPM) program. However, such interactions are seldom explored during plant breeding programs. Therefore, in the present study, we compared the performance of the omnivorous biological control agent Orius laevigatus on six tomato genotypes with different levels of resistance to the tomato leaf miner Phthorimaea absoluta. We found that the O. laevigatus fitness components (i.e., egg deposition, egg hatching rate, and duration of egg, early nymphal, late nymphal stages, and their survival) were inferior on the wild resistant genotypes (LA 716 and LA 1777) in comparison to the resistant domesticated genotype EC 620343 and the susceptible genotypes (EC 705464 and EC 519819). It appears that the adverse effects of tomato genotypes on O. laevigatus are determined mainly by glandular and non-glandular trichome densities on the leaves. Comparison of O. laevigatus response to the tested tomato cultivars to that of P. absoluta revealed significant positive correlations in duration of the egg stages, development time of early and late larval stages, and overall immature mortality in both species. It appears, therefore, that defensive plant traits operate in a similar way on the pest and its predator in the system. Overall, the present study of the tomato-P. absoluta-O. laevigatus system provides experimental evidence for the need to optimize pest management by employing intermediate levels of crop resistance together with biological control agents.
