In the present study some bio-ecological characteristics of Lilioceris lilii in Bosnia and Herzegovina are presented. The insect’s presence was confirmed in the majority of the researched locations in Bosnia and Herzegovina. The average body length of L. lilii was 7.64 mm (7.025 mm for the males while 8.106 mm for the females) and the average body width 3.75 mm. The average length of a fully developed larva was 6.36 mm, and the average width was 2.69 mm. In terms of the cocoon, the average length was 8.83 mm and its width was 5.82 mm. Duration of embryonic development under field conditions was 8.5 days in average. The average duration of larval development (4 instars) was 16 days and the pupal stage lasted approximately 18 days. Lilioceris lilii retreated into winter quiescence at the beginning of autumn, thereof completes one generation per year. In the area of Sarajevo in field conditions the number of the laid eggs per female was 130 in average. The insect undergoes its entire development at the Asian and Oriental species of lily, on all the above-ground parts of the plants. Lilium candidum lily species that was present in all home gardens in the observed areas was the major host of the L. lilii. Experimentation with Aloae vera proved that this species was not a host of L. lilii.

Abstract L. lilii is a Eurasian chrysomelid beetle that was first found in Quebec, Canada, in 1943, from where it has spread to several Canadian Provinces, and Vermont and Maine in the USA. It was also reported in Boston, Massachusetts, in 1992, and it is now found in several New England States. It is also alien and invasive in the UK and, probably, in Northern Europe. The beetle most probably spreads with the sale and movement of potted lilies, flowering bulbs or cut flowers. In countries where it is invasive, it is a serious pest of cultivated lilies and fritillaries. Without control methods, leaves and flowers are totally defoliated by larvae. In North America, it also represents a threat to native lilies.

Conservation Concern

Invasive species are among the leading threats to global ecosystems due to impacts on native flora and fauna through competition and predation. The lily leaf beetle, Lilioceris lilii Scopoli (Coleoptera: Chrysomelidae), is an invasive pest of lilies (Lilium spp.) and other genera of Liliaceae (Liliales). A habitat suitability model was created using Maxent, to help predict if L. lilii will be able to establish in locations were native North American Liliaceae species grow. The model was created using georeferenced occurrence records from the beetle’s native, naturalized, and invasive range. Model results indicate that precipitation in the driest quarter and annual average temperatures are most strongly correlated with L. lilii distribution, and suggest that the species will perform poorly in very dry, hot, or cold environments. The model also indicates that the beetle should be able to establish throughout the range of most North American Liliaceae genera, including species of special conservation concern. This model can be used by natural area managers to identify areas of high habitat suitability that overlap with vulnerable North American Liliaceae species, and prioritize L. lilii monitoring and control activities as the beetle continues to expand its range.

A change in growth rate of the halibut from the Portlock-Albatross grounds has occurred since the early 1930's. It is possible to measure this change in growth by studying the otoliths of fish taken by the commercial fishery in subsequent years. The calculation of body lengths from otolith measurements has provided a technique of reconstructing the growth patterns of each year-class. This method has been tested using the otoliths of recovered tagged halibut. The percentage deviations from average body length at each age demonstrate an increase in average length with time over the period 1920–1956. This increase is not exhibited among young fish of ages 1 through 4; it starts approximately with age 5 and continues throughout the older ages, where it is pronounced.

The Town

The lily leaf beetle, Lilioceris lilii (Scopoli) (Fig. 1), was first noticed in Portage la Prairie (49°58′N, 98°20′W), about 90 km west of Winnipeg, in June and July 1999. The beetles were present on Asiatic lily varieties only, especially tiger lilies (Lilium tigrinum Ker-Gawl (Liliaceae)). Larvae and adults were observed at two locations in the northeastern section of the town. The plants that were attacked were completely defoliated.

The study aimed to determine the size and physical description (location, shape, colour and texture) ovarian of Echymipera kalubu. Study was conducted in 3 months from June to September 2017. Three female E. kalubu with an average body weight 399±97.32g and average body length 21.67±5.51cm were used in this study. Sample of bandicoots were dissected using a surgical tool and then measured using measuring tester and analytic scales. Descriptive statistics was used to analyse the data. The results showed that average length of female reproductive organs of E. kalubu was 11,00±0,87 cm (right) and 11,03±0,83 cm (left); average weight of ovarian was 0,01±0,0048 g (right) and 0,02±0,0006 g (left). This study also showed that characteristics of ovarian were in common with other polytocus animals.

Fecal Shield

The lily leaf beetle, Lilioceris lilii Scopoli, was first found in North America near Montreal, Canada, in 1943 (LeSage 1992). It was recovered in Boston, Massachusetts, in 1992 (Livingston 1996), and now occurs throughout all of the New England states and in the Canadian provinces of Quebec, Ontario, Nova Scotia, and Manitoba. It is a serious pest of native and cultivated lilies (Liliaceae) (Livingston 1996). This univoltine insect overwinters as an adult and after initiating feeding in the spring, oviposits in rows on the undersides of lily leaves. Larvae, which carry a fecal shield, pass through four instars before pupating in the soil. In North America, larval feeding often results in complete plant defoliation. Lilioceris lilii apparently originated in Asia (Berti and Rapilly 1976), and now exists throughout Eurasia from Siberia to Morocco and from the United Kingdom to China (Labeyrie 1963; Lu and Casagrande 1998). Based on its Eurasian distribution, L. lilii will likely increase its distribution in North America.
