“…Epizootics caused by insect pathogens are signi cantly in uenced by environmental factors (biotic and abiotic), and in most cases, these factors such as sunlight, temperature, precipitation, and humidity are among the most in uential factors in epizootic processes [30,31]. These environmental factors (the weather parameters) are also known to in uence the colony growth of bumblebees and the incidence of various pests and diseases [32][33][34][35].…”

“…For example, Sharma et al [35] examined the seasonal incidence of various pests and diseases in B. haemorrhoidalis (Smith, 1852) (Hymenoptera: Apidae) colonies grown in the laboratory. As a result, it was determined that temperature and partial humidity directly affected the incidence of many pests and diseases during sampling and eld establishment.…”

Purpose Bumblebees are an important group of insects in the pollination of various vegetables, fruits, oilseeds, legumes, and the fodder crops. Compared to honeybees, they have a wider choice of hosts and a longer flight period. These bees are used especially for the pollination of plants in greenhouses and are commercially produced for this purpose. Recently, serious decreases have been occurring in bumblebee populations due to various reasons such as pathogens and parasites, and some of species are even threatened with extinction. In this study, the presence of various pathogens and parasites was investigated by PCR in Turkish populations. Methods A total of 172 Bombus terrestris (Linnaeus,1758) samples (21 samples from commercial enterprises, 79 samples from greenhouses and 72 samples from nature) collected from three provinces (Antalya, Mersin and İzmir) where greenhouse cultivation is intensively carried out in Turkey. 89 of these samples were collected in the spring and 83 in the fall. Results The overall prevalence of Nosema bombi, Crithidia bombi, Apicyctis bombi and Locustacarus buchneri was determined as 7.55%, 9.3%, 11.62% and 4.65%, respectively. Co-infections (5.81%) were only detected in nature samples. C. bombi and A. bombi infections were detected at higher rates in the spring samples than the autumn samples (p < 0.05). Conclusion The obtained results could be important in determining the spread rates of the bumblebee diseases in Turkey and in the control of these diseases. More studies are needed to determine the transmission pathways of these pathogens between the populations.

“…We did not find evidence for the presence of N. bombi in the South Island, although it is possible that this pathogen could be found with additional sampling. However, infection rates of bumble bees by N. bombi can also exhibit a positive correlation with temperature and humidity (Sharma et al 2021). Perhaps N. bombi is not tolerant of cooler temperatures, as we have observed in other insect pathogens in New Zealand (Lester & Bulgarella 2021), or it is possible that this pathogen has not yet dispersed to the South Island.…”

The gut microbiome is an important component of bee health. Previous research around the globe indicated that bee gut microbiome can be affected by the presence of pathogens. We surveyed for the presence of three specific pathogens in populations of the buff-tailed bumble bee, Bombus terrestris (Linnaeus, 1758), across New Zealand. The pathogen Crithidia bombi was the most prevalent and widespread pathogen across the studied sites, with prevalence ranging from 30 to 100% of the bees examined. Nosema bombi was, however, only found in North Island sites. The Deformed wing virus was detected in bumble bees at all the sites except one (Twizel in the South Island) with prevalence ranging from 0 to 60%. The B. terrestris gut microbiome and the associated pathogens from two contrasting locations were studied. Bacteria such as Snodgrassella alvi and Lactobacillales were observed. We also found that infections with C. bombi were associated with more diverse, distinct gut microbiome perhaps indicating disruptions of gut microbe communities that contribute to impair bumble bees' health.

The second largest and most well-known insect order Lepidoptera includes both butterflies and moths in the world. This study was started based on secondary information from present literature from different countries on the flora and fauna. So far, much study work was completed on this subject but those workers were not existing to the extension employees, policymakers, and the public in an efficient way to date. In this review paper, we can give the recent data on etymology, distribution and diversity, external morphology, different morphological parts of caterpillar, internal morphology, digestive system, circulatory system, reproduction and growth, respiratory system, and growth and role of the olfactive process in larval and adult lepidopteran insects. There are over one hundred and eighty thousand Lepidoptera species described, divided into one hundred and twenty-six families and forty-six superfamilies, and the total number of living beings was labeled as about ten percent. A result found is that the species of moths is about one hundred sixty thousand compared to one hundred seventy thousand five hundred species of butterflies in the world. Butterflies are an important category of insects that can function as sensors of environmental change. Butterflies are insects from the order Lepidoptera's macro-lepidopteran clade Rhopalocera. The study focused on the lepidopteran insects and the diversity of the world. It presents the review of research imperfect data on specific knowledge in diverse agroecological zones. This study acknowledged investigating breaches in different countries of the world. It also provides information on lepidopterans as alternative food and financial source of the world. It also helps in the sustainable agricultural field.
