Climate change has affected the geographical distributions of most species worldwide; in particular, insects of economic importance inhabiting tropical regions have been impacted. Current and future predictions of change in geographic distribution are frequently included in species distribution models (SDMs). The potential spatial distributions of the fruit fly Anastrepha striata Schiner (the main species of agricultural importance in guava crops) under current and possible future scenarios in Colombia were modeled, and the establishment risk was assessed for each guava-producing municipality in the country. The SDMs were developed using 221 geographical records in conjunctuin with nine scenopoetic variables. The model for current climate conditions indicated an extensive suitable area for the establishment of A. striata in the Andean region, smaller areas in the Caribbean and Pacific, and almost no areas in the Orinoquia and Amazonian regions. A brief discussion regarding the area suitability for the fly is offered. The expansion of the suitable area was observed in all future scenarios; moreover, this effect was more pronounced in the Amazonian region. The Colombian guava-producing municipalities were classified according to the degree of vulnerability to the fly establishment as follows: 42 were high-risk, 16 were intermediate-risk, and 17 were low-risk. The implementation of future integrated management plans must include optimal spatial data and must consider environmental aspects, such as those suggested by the models presented here. Control decisions should aim to mitigate the positive relationship between global warming and the increase in the dispersal area of the fruit fly.

“…In stage‐structured models, the duration of a stage may vary among individuals. For example, eggs laid at the same time do not hatch simultaneously (Bolzan, Nava, Smaniotto, Valgas, & Garcia, ; Moriyama & Numata, ). The same principle applies to any other life stages.…”

Census timing alters stage duration distributions in matrix population models

Matrix population models are widely used to study the dynamics of stage‐structured populations. A census in these models is an event monitoring the number of individuals in each stage and occurs at discrete time intervals. The two most common methods used in building matrix population models are the prebreeding census and postbreeding census. Models using the prebreeding and postbreeding censuses assume that breeding occurs immediately before or immediately after the censuses, respectively. In some models such as age‐structured models, the results are identical regardless of the method used, rendering the choice of method a matter of preference. However, in stage‐structured models, where the duration of the first stage of life varies among newborns, a choice between the prebreeding and postbreeding censuses may result in different conclusions. This is attributed to the different first‐stage duration distributions assumed by the two methods. This study investigated the difference emerging in the structures of these models and its consequence on conclusions of eigenvalue and elasticity analyses using two‐stage models. Considerations required in choosing a modeling method are also discussed.

Biological aspects and thermal requirements in four species of Chrysopidae (Neuroptera The Chrysopidae family is the most diverse in the order Neuroptera and lacewings are considered promising biological control agents, because they feed on a wide variety of small insect pests. The objective of this work was to compare the biological and reproductive aspects, to determine the thermal requirements and to establish the climatic zoning of four species of lacewings, Chysoperla externa (Hagen), Ceraeochrysa cubana (Hagen), Ceraeochrysa cincta (Schneider) and Ceraeochrysa paraguaria (Navás) for the state of São Paulo. The results showed that the four species of lacewings were able to complete their eggadult cycle in the thermal range of 18 to 32 °C and the best viability obtained between 22 and 28 °C. It was observed that the Ch. externa species had a faster development than the other species at each stage of development and the eggadult cycle. In the fertility life table, the population growth was favored in the thermal range of 22 and 28 °C for Ce. cincta, from 22 to 25 °C for Ce. paraguaria, from 25 to 28 °C for Ch. externa and for Ce. cubana temperature at 28 °C. The thermal requirements of the species indicated that the base temperature (Tt) were 10.5, 12.95, 11.99, and 11.77 °C and the thermal constant were 443.81, 362.7, 399.68, and 314.95 DD for Ce. cincta, Ce. cubana, Ce. paraguaria and Ch. externa, respectively. Through the thermal requirements and the use of computational tools such as the Geographic Information System (GIS), it was possible to represent spatially the development of the four species of lacewings. It was observed that the estimated number of monthly generations was influenced by temperature, and in the warmer months the life cycle was faster than in the colder months. Due to the shorter life span of Ch. externa, this species managed to complete 14 generations/year, with the remaining 10 to 11 generations/year in the warmer regions of the state of São Paulo. In colder regions, the number of estimated annual generations for each species was lower. In addition, it was observed that among the species studied, Ch. externa can be indicated for regions with mild to warm temperatures, Ce. cincta for mild climates to cold, Ce. paraguaria for regions with mild temperatures and Ce. cubana regions to warm temperatures. The data obtained in this study could be used for mass rearing the species, to help predict the occurrence of predators in the field and to choose which of the species are best adapted to certain climates in the environment aiming the use of these predators in Integrated Pest Management programs.
